200932565 九、發明說明 【發明所屬之技術領域】 本發明係有關於印表機領域且特別是頁寬噴墨印表機 【先前技術】 本案申請人已發展出廣範圍的印表機，其使用頁寬列 印頭，而非傳統的往復列印頭設計。頁寬設計增加列印速 率，因爲列印頭不須橫越頁面往復運動以沉積一列影像。 頁寬列印頭單純地沉積墨水在媒介上，因爲其高速地運動 通過媒介。此等列印頭已能夠以每分鐘約60頁的速率執 行全彩（full color ) 1 600 dpi的列印，此速率在以前用傳 統噴墨印表機是無法達到的。 高列印速率需要一大的供墨流率。不只是流率要高而 已，將墨水沿著一頁寬列印頭的整個長度配送比給墨至一 相對小的往復式列印頭要複雜許多。 爲了要延長列印頭的壽命，絕大部分的噴墨印表機都 加入某些種類的維護設施。在列印頭沒有使用的時候蓋住 列印頭是其中一種簡單的方式。將列印頭加蓋可讓噴嘴上 的墨水不會乾掉。然而，這無法將已經附著在該噴嘴面上 的紙張灰塵或其它污染物清除掉。最有效的方式爲，用一 適當的表面擦拭該噴嘴面來清除這些微粒。 典型地，用一彈性的擦拭表面將污染物從該噴嘴表面 上清除掉是最有效的。然而，已被發現的是，當該擦拭器 -5- 200932565 在一擦拭器操作期間第一次接觸該噴嘴面的時候’ 表面中的彈性物質的衝擊足以造成墨水彈離該噴嘴 當該擦拭器彈離該噴嘴面時，即無接觸壓力’因此 潔部分的噴嘴面。 【發明內容】 因此，本發明提供一種用於噴墨印表機之列印 設施，該噴墨印表機具有一列印頭其具有一界定一 列的噴嘴面，該列印頭維護設施包含： 一擦拭器構件用來擦拭該噴嘴面； 一底座用來支撐該擦拭器構件；及 一維護驅動器，用來選擇性地在不同的速率下 擦拭器構件。 藉由一變速維護驅動器，該擦拭器可在一較慢

機械構造。建構週邊構造（例如外殼、饋紙盤、紙收集盤 、、、等），使其適合印表機（例如相片印表機、網路印 表機、或蘇活印表機）的特定列印要求。申請人揭露在共 同繫屬中的申請案USSN 11/688863 (我們的案號 RRE 001 US )之相片印表機，是使用圖1之流體工學系統 之噴墨印表機的例子。該共同共同繫屬中的申請案的內容 於此倂入作爲參考。USSN 11/872719號案（我們的案號 SBF 0 09US )中詳細描述該系統的作業和其個別組件，其 內容於此倂入作爲參考。 簡言之，印表機流體工學系統具有列印頭組合體2 , 墨水罐4經由上游墨水管線8供給墨水至列印頭組合體2 。廢棄墨水經由下游墨水管線排至廢墨水罐1 8。爲了簡 化，所以只顯示單一墨水管線。實際上，列印頭具有多條 -9- 200932565 墨水管線供全彩列印。上游墨水管線8具有關閉閥 用於選將列印頭組合體2擇性地與泵12和/或墨； 隔離。泵1 2用於主動塡注或溢滿（flood )列印頭組 2。泵12也用於建立墨水罐4內的負壓。在列印期間 由氣泡點規制器6維持負壓。 列印頭組合體2是液晶聚合物模組20，其支擦 列的列印頭積體電路3 0 ;以黏性晶粒附接薄膜（未 )固定該等列印頭積體電路3 0。列印頭積體電路3 0 陣列的墨水噴射噴嘴，用於噴射墨水液滴至正在通過 介基板22。噴嘴是以真實1600 dpi (亦即1600 npi 嘴節距）或更大解析度列印的微電子機械構造。 USSN 1 1/246687 (我們的案號 MNN 001US)中詳細 述合適列印頭積體電路3 0的製造和構造，其內容倂 此作參考。液晶聚合物模組2 0具有在入口 3 6和出丨 之間延伸的主通道24。主通道24饋給一系列延伸至 聚合物模組20下側的細通道28。細通道28經由晶 接薄膜內之雷射切除孔而將墨水供給至列印頭積體 30 ° 在主通道24上方的是一系列未塡注的空氣凹穴 設計這些凹穴以在塡注列印頭期間侷限一袋的空氣。 空氣袋給予系統一些順應性，以吸收和阻尼墨水中的 高點和液壓衝擊。印表機是具有大數目噴嘴快速地發 高速頁寬印表機。此印表機快速率地消耗墨水，且突 束列印工作或甚至只是一頁的結束，意涵朝向（和經 10， 罐4 合體 ，藉 一系 示出 具有 的媒 的噴 地描 入於 1 3 8 液晶 粒附 電路 26 = 該等 壓力 射的 然結 過） -10- 200932565 列印頭組合體2運動的一行墨水必須幾乎瞬間停止。如果 沒有空氣凹穴2 6提供的順應性，則墨水的動量會溢滿列 印頭積體電路30的噴嘴。再者，後續的「反射波」會產 生足以去除噴嘴塡注的強負壓。 列印引擎 圖2A顯示使用列印匣2類型之列印引擎3。列印引 擎3是噴墨印表機的內部構造，所以其不包括任何外部殼 體、墨水罐、或媒介饋給和收集盤。使用者將閂1 26上升 或下降，以插入或移除列印頭匣2。列印引擎3和列印頭 匣2上的接點形成電性連接，且分別藉由承座120、入口 歧管48、和出口歧管50形成流體耦合。 藉由主驅動輥186和排出饋給輥178，將媒介片體饋 給經過列印引擎。主驅動輥1 8 6被主驅動皮帶輪和編碼器 碟1 8 8所驅動。排出饋給輥1 7 8被排出驅動皮帶輪1 8 0所 驅動。藉由媒介饋給皮帶182’使排出驅動皮帶輪180和 主驅動皮帶輪188同步。媒介饋給馬達190經由輸入驅動 皮帶192供給動力給主驅動皮帶輪188。 主驅動皮帶輪188具有編碼器碟，驅動皮帶輪感測器 184讀取編碼器碟。驅動軸桿186、178之迴轉數和速率 的相關資料，被送至列印引擎控制器（PEC )。列印引擎 控制器（未示出）被安裝至主印刷電路板（PCB ) 194 ’ 且是用於控制印表機作業的主要微處理器。 圖2 B顯示已移除列印頭匣後的列印引擎3 ’以顯露 -11 - 200932565 每一承座120中的孔122。每一孔122容置入口歧管 口歧管上的其中之一嘴52(見圖5)。如上所述，墨 具有任意位置和構造，但是簡單地連接至入口親合器 座120後面處的中空嵌入口 124 (見圖8)。在出口 器後面處的嵌入口 124’連通至廢墨水罐(見圖1 的廢棄墨水出口。 補強支承表面128被固定至列印引擎3的受壓金 體1 96。這些提供用於將列印頭匣設置在列印引擎內 考點。他們也被設置用於在安裝時對作用在匣2上的 負載，提供正相反的支承表面。當歧管嘴（下述）打 印引擎中的關閉閥（下述）時，流體耦合器120推抵 之入口歧管和出口歧管。匣2上之閂126的壓力，也 反於支承表面128。設置支承表面128使其直接相反 2中的壓縮負載，可降低匣內的彎曲和變形。最後， 助噴嘴相對於媒介饋給路徑的經確定位。其亦保護匣 度較弱的機構免於損壞。 列印頭匣 圖3是完整的列印頭匣2的透視圖。列印頭匣2 頂模組44和可移除的保護罩42。頂模組44具有中 板供構造性勁度，且用於提供具紋理的夾持表面58 在插入和移除期間操縱匣。在安裝於印表機內之前’ 罩42的底部保護列印頭積體電路（未示出）和整列 點。蓋體56

的列印頭匣，以包住殘留墨水的洩漏。圖5是列印頭組合 體2的局部分解透視圖。已移除頂罩以顯露入口歧管48 和出口歧管50，已移除入口圍板和出口圍板46、47以較 清楚地暴露五個入口嘴52和五個出口嘴54。入口和出口 歧管48、50形成每一個別入口及出口和液晶聚合物內主 通道（見圖6之24 )之間的流體連接。主通道延伸液晶 聚合物的長度，且主通道饋給在液晶聚合物模組下側上的 一系列細通道。一列空氣凹穴26形成在每一主通道24的 上方。如上關於圖1所述’藉由壓縮空氣凹穴26內的空 氣，而阻尼墨水中的衝擊波或壓力脈衝。 圖6是沒有入口或出口歧管或頂罩模組之列印頭組合 體的分解透視圖。每一種墨水顏料用的主通道24和其相 關的空氣凹穴26，分別形成在通道模組68和凹穴模組72 內。晶粒附接薄膜6 6黏複製通道模組6 8的底部。晶粒附 接薄膜66將列印頭積體電路3〇安裝至通道模組，使得通 道模組ό 8下側上的細通道經由貫穿薄膜的小雷射切除孔 而和列印頭積體電路30呈流體連通。 因爲液晶聚合物的勁度及熱膨脹係數的原因，所以通 道模組68和頂罩模組72兩者都是由液晶聚合物所模製成 型，且液晶聚合物的熱膨脹係數和矽的熱膨脹係數緊密地 -13- 200932565 匹配。可瞭解的是’例如頁寬列印頭的相對長構造，應該 使列印頭積體電路30的矽基板和其支撐構造之間的任何 熱膨脹差異最小化。 列印頭維護轉盤 參考圖7 ’顯示剖面透視圖。該剖面是穿過圖2A所 示的線7-7。列印頭匣2插入列印引擎3內，使得其出口 歧管50和嵌入口 124呈流體連通，該嵌入口 124引導至 印表機成品內之廢棄墨水罐（通常位於列印引擎的基座） 。液晶聚合物模組20支撐列印頭積體電路3〇緊鄰著延伸 穿過列印引擎的媒介饋給路徑22。 列印頭維護轉盤1 5 0和其相關的驅動機構，位在媒介 饋給路徑22的相反側上。安裝列印頭維護轉盤〗50用於 繞著管狀驅動軸桿156旋轉，列印頭維護轉盤丨50也被建 構用於朝向和遠離列印頭積體電路30運動。藉由升高轉 盤1 5 0朝向印頭積體電路3 0，轉盤外部上的各種列印頭 維護站呈現至列印頭。維護轉盤150可旋轉地安裝在舉升 構造170上，其安裝至舉升構造軸桿156，所以其能相對 於列印引擎3的其餘構造樞轉。舉升構造〗70包括一對舉 升臂158(只顯示一支舉升臂，另一支舉升臂設在舉升構 造軸桿156的相反端）。每一舉升臂158具有凸輪嚙合表 面168 ’例如低摩擦材料的輥或墊。凸輪（下文詳述）固 定至轉盤驅動軸桿160，用於以該軸桿160轉動。舉升臂 158被偏壓進入和轉盤舉升驅動軸桿16〇上的凸輪嚙合， -14- 200932565 使得轉盤舉升馬達（下述）能藉由旋轉軸桿160而運動轉 盤朝向和遠離列印頭。 維護轉盤150繞管狀軸桿166的旋轉，是獨立於轉盤 舉升驅動。轉盤驅動軸桿166嚙合轉盤旋轉馬達（下述） ’使得無論其從列印頭縮回或朝向列印頭前進，其皆能被 轉動。當轉盤朝向列印頭前進時，擦拭器刮片1 6 2運動經 過媒介饋給路徑22，以擦拭列印頭積體電路30。當轉盤 150從列印頭撤回時’轉盤150可重複地轉動，使得擦拭 器刮片（wiper blade) 162 嚼合刮刀（doctor blade) 154 和清潔墊152。此也在下文詳細討論。 現在參考圖8，剖面7-7顯示在平面視圖中，以較清 楚地描述維護轉盤舉升驅動。轉盤舉升驅動軸桿160顯示 呈轉動，使得舉升凸輪172藉由凸輪嚙合表面168將舉升 臂158向下推動。舉升軸桿160被轉盤舉升正齒輪174驅 動，該轉盤舉升正齒輪174依序被轉盤舉升蝸輪176驅動 ^ 。以鍵將蝸輪17固定至轉盤舉升馬達的輸出軸桿（下述 )。 隨著舉升臂158將舉升構造170向下拉，維護轉盤 150從列印頭積體電路30撤離。在此位置中，轉盤50旋 轉時，沒有維護站接觸列印頭積體電路30。但是轉盤會 帶動擦拭器刮片162接觸刮刀（doctor blade ) 154和具吸 收性的清潔墊152。 舌[j 刀(doctor blade ) -15- 200932565 刮刀154結合清潔墊152工作，以廣泛地清潔擦拭器 刮片162。清潔墊152從擦拭器刮片162的擦拭接觸面擦 拭紙塵和乾掉的墨水。但是小墨水珠和污物會形成刮片 162的尖端，該尖端不接觸清潔墊152的表面。 爲了去除此墨水和塵，將刮刀1 54安裝在列印引擎3 內’以在刮片1 62擦拭過列印頭積體電路30以後但在接 觸清潔墊1 52以前，使刮刀154接觸刮片162。當擦拭器 刮片1 62接觸刮刀1 54時，擦拭器刮片1 62撓曲成弧形以 便通過。因爲擦拭器刮片162是彈性體材料，所以當其一 脫離刮刀154時，便彈回至其靜止的直形狀。快速地彈回 至其靜止的形狀，會從擦拭器刮片162 (特別是從尖端） 投射出塵和其他污物。 普通的工作者會瞭解，當擦拭器刮片162接觸清潔墊 152時也會撓曲’且一旦擦拭器刮片162脫離墊時，也同 樣地會彈回至其靜止的形狀。但是刮刀1 5 4放射狀地安裝 成在轉盤150的中心軸桿166較接近而在清潔墊152處較 遠離。此配置使得當擦拭器刮片162通過時會更彎曲，且 當彈回至靜止的形狀時，給污物更多的動量。因爲清潔墊 152接觸前導刮片使拖在後面的刮片不當地擦過清潔墊 152，所以不可能將清潔墊152單純地運動至更靠近轉盤 軸桿166，以使擦拭器刮片162更彎曲。 清潔墊 清潔墊152是具吸收性的發泡體，其被形成爲對應於 -16- 200932565 擦拭器刮片162之圓形路徑的弧形。當以編織材料覆蓋墊 1 52，以在擦拭刮片時提供許多密集的聚集接觸點，使墊 152更有效率地清潔。因此，編織材料之線的尺寸應相對 地小，例如小於2丹尼（denier )。具有線尺寸約1丹尼 之微纖維材料的工作狀況特別佳。 清潔墊152延伸擦拭器刮片162的長度，擦拭器刮片 162也延伸頁寬列印頭的長度。頁寬清潔墊152同時清潔 擦拭器刮片的全部長度，其減少每一擦拭作業所需的時間 。再者，頁寬清潔墊的長度固有地提供大體積的吸收性材 料，用於保持相對大量的墨水。因爲有較大的吸收墨水能 力，所以較不須常常更換清潔墊152。 加蓋於列印頭 圖9顯示具有安裝至維護轉盤150之加蓋維護站198 的加蓋列印頭積體電路30的第一階段。當舉升凸輪172 向下推在舉升臂158上時，維護轉盤150從列印頭積體電 路30撤離。維護轉盤150連同維護編碼器碟204被旋轉 ，直到第一轉盤旋轉感測器2 0 0和第二轉盤旋轉感測器 202決定：列印頭加蓋器正面對列印頭積體電路3 0。 如圖10所示，舉升軸桿160轉動凸輪172，以致舉 升臂158向上運動，以使維護轉盤150向列印頭積體電路 30前進。加蓋器維護站198嚙合液晶聚合物模組20的下 側，以將列印頭積體電路3 0的噴嘴密封在相對潮濕的環 境中。普通的工作者會瞭解：此防止（至少延長）噴嘴免 -17- 200932565 於乾掉和阻塞。 去除列印頭的蓋 圖1 1顯示去除蓋以準備列印的列印頭積體電路3 0。 旋轉舉升軸桿160，以致舉升凸輪172將轉盤舉升臂158 向下推。加蓋維護站1 98運動離開液晶聚合物模組20， 以暴露列印頭積體電路3 0。 擦拭列印頭 圖12顯示正被擦拭器刮片162擦拭的列印頭積體電 路30。當加蓋站198被旋轉離開列印頭時，擦拭器構件 的刮片162接觸液晶聚合物模組20的下側。當轉盤150 繼續旋轉時，擦拭器刮片被拉經過列印頭積體電路3 0的 噴嘴面，以擦掉任何紙塵、乾掉的墨水、或其他污物。擦 拭器刮片1 62由彈性體材料形成，所以當他們擦拭通過列 印頭積體電路時，其彈性地撓曲和彎曲。當每一擦拭器刮 片的尖端被彎曲時，每一刮片的側表面和噴嘴面形成擦拭 接觸。可瞭解的是：刮片的寬廣平坦側表面和噴嘴面有較 大的接觸，且更有效率地清除掉污物。 擦拭器刮片清理（清潔） 圖13、14顯示正被清潔的擦拭器刮片162。如圖I3 所示，在擦拭器刮片1 62擦拭列印頭積體電路3 0之後’ 擦拭器刮片162立即被旋轉通過刮刀154。刮刀154的功 -18- 200932565 能在上文附標題「刮刀」中較詳細地討論。 在將擦拭器刮片162拖拉經過刮刀154以後，附著在 刮片的任何殘留塵和污物，被具吸收性的清潔墊1 52所移 除。此步驟顯示在圖14中。 在此過程期間，列印壓盤維護站206正好相對著列印 頭積體電路3 0。如果想要的話，藉由旋轉舉升凸輪172 能舉升轉盤，使得噴嘴能發射進入吸收性材料208。混合 在墨水噴嘴的任何顏料立即被淨化。鑽削進入管狀底座 166之側面的孔（未示出），提供吸收性材料208和在轉 盤軸桿166之中心凹穴內的多孔材料210之間的流體連通 。被材料208所吸收之墨水，被拉入多孔材料210內且被 多孔材料210所保持。爲了使多孔材料210流乾，轉盤 150可設有真空附接點（未示出），以排掉廢棄墨水。 轉盤150帶著乾淨的擦拭器刮片繼續旋轉（見圖15 )’直到列印壓盤2 0 6再度位在列印頭積體電路3 0的對 面。然後如圖16所示，轉盤朝向列印頭積體電路30上升 ’以預備列印。沿著媒介饋給路徑22饋給媒介基板片體 並通過列印頭積體電路30。就滿版出血（full bleed;列 印至媒介片體的極邊）列印而言，媒介基板能保持離開壓 盤206’以致其不會因墨水過度噴灑而弄髒。可瞭解的是 ’吸收性材料2 0 8設置在列印壓盤2 0 6的凹陷部份內，以 致任何過度噴灑的墨水（通常在紙兩側邊緣約1毫米）被 保持離開可接觸媒介基板的表面。 在列印工作結束時或在印表機將進入待命模式之前， -19- 200932565 轉盤1 50在旋轉中從列印頭積體電路3 0撤離，以致列印 頭加蓋維護站1 98再度呈現至列印頭。如圖1 7所示，舉 升軸桿160轉動舉升凸輪158，以致舉升凸輪158將列印 頭加蓋維護站運動進入和液晶聚合物模組20的下側密封 嚙合。 列印頭維護轉盤 圖18、19、20、和21顯示隔離的維護轉盤。圖18 是顯示擦拭器刮片1 62和列印壓盤206透視圖。圖1 9是 顯示列印頭加蓋器1 98和擦拭器刮片1 62的透視圖。圖 20是顯示維護轉盤之零組件的分解圖。圖21是顯示完全 組合後之零組件的剖視圖。 維護轉盤具有四個列印頭維護站：列印壓盤206、擦 拭器構件162、和集墨器（spittoon )/吸墨器220。每一 維護站安裝至其自己的外部底座組件。外部底座組件安裝 在轉盤管狀軸桿166的周圍，且彼此相互嚙合以鎖固至軸

也是共同模製的構造，其具有被支撐在硬塑膠基座270上 ^ 的軟彈性體擦拭刮片268。爲了擦拭列印頭積體電路30 的噴嘴面，轉盤底座23 6被升高然後旋轉，所以擦拭器刮 片268擦過噴嘴面。通常旋轉轉盤底座236，使得擦拭器 刮片268朝向囊狀小珠擦拭。如同在申請人共同共同繫屬 中之檔案編號RRE015US的申請案（倂入作交互參考）中 所討論者，可設計囊狀小珠的輪廓用於幫助塵和污物卡在 擦拭器刮片268的面上。但是如果證明在兩個方向中擦拭 更有效率，則可容易地將維護驅動（未示出）建構成用於 在兩個方向中轉動底座236。類似地，藉由改變旋轉的數 -25- 200932565 目，很容易改變擦拭經過列印頭積體電路30的次數。程 式設計維護驅動，以執行每一擦拭作業。 在圖25中顯示維護轉盤150的列印頭加蓋器272呈 現至列印頭積體電路30。圖32獨立地顯示加蓋器，以較 清楚地例示其構造。加蓋器272具有由軟彈性體材料形成 的周圍密封274。周圍密封274和其硬塑膠基座276共同 模製。在印表機閒置時，列印頭加蓋器272降低噴嘴乾掉 的速率。周圍密封2 74和液晶聚合物模組2 0下側之間的 密封不需完全地不透空氣，因爲加蓋器正被用於以吸力塡 注列印頭。事實上，硬塑膠基座276應包括空氣呼吸器孔 278，使得噴嘴不會因去除列印頭的蓋子時所造成的吸力 而溢滿氾濫。爲了蓋住列印頭，旋轉底座23 6直到列印頭 加蓋器272呈現至列印頭積體電路30。然後升高底座236 ，直到周圍密封2 7 4嚙合列印頭匣2。 圖26顯示包括擦拭器刮片清潔墊152。如同上文第 一實施例所述，清潔墊152安裝在印表機內，使得當維護 轉盤150旋轉時，擦拭器刮片268運動經過墊152的表面 。藉由設置清潔墊152的位置，使得底座23 6須從列印頭 積體電路30縮回，以允許擦拭器刮片26 8接觸清潔墊， 且以相對高速的速率轉動底盤236，用以廣泛地清潔擦拭 器刮片2 6 8，而和列印頭積體電路3 0無任何損害性接觸 。再者，可用介面活性劑濕潤清潔墊1 5 2，以更容易從擦 拭器刮片表面移除污物。 圖27獨立地顯示射出成型底座23 6。底座相對於穿 -26- 200932565 過中心縱長軸線282而延伸的二平面呈對稱。此對稱是重 要的，因爲，如果沿著頁寬列印頭之長度而延伸的射出成 型底座236不對稱，則當其冷卻時’有變形和彎曲的傾向 。因爲具有對稱的剖面，所以當底座冷卻時’其收縮也是 對稱的。 底座236具有形成在其外部表面的四個維護站安裝承 座276，該等承座276都相同，所以其能容至各種維護站 206、266、262、272其中任何一個。以此方式，各維護 站變成可互換的模組，且可改變各維護站呈現至列印頭的 順序，以適合不同的印表機。再者’如果修改各維護站本 身，則其標準承座確保維護站只須最少的設備更換便能容 易地倂入現有的生產線內。以黏劑將維護站固定在承座內 ，但是其他的方法（例如超音波點熔接或機械式相互嚙合 )也合適。 如圖28所示，模具設有四個滑塊278和一個中央芯 部288。每一滑塊278具有柱狀構造280以形成導管，該 導管將纖維芯墊連接至中心凹穴內的多孔材料219。用於 每一滑塊的拉引線是從底座236輻射狀地向外，而芯部 28 8是縱向地縮回（可瞭解的是，芯部不是精密的圓柱， 而是截頭圓錐，以提供需要的通氣）。聚合物組件的射出 成型非常適合於大量且低成本的生產。再者，底座的對稱 構造和均勻收縮維持良好的公差，以保持維護站平行於列 印頭積體電路而延伸。但是其他的製造技術也可能，例如 壓縮聚合物粉末的衝擊波或類似者。再者，增加親水性的 -27- 200932565

表機可需要一個用於將墨水溶劑或其他清潔流體噴射至噴 嘴面上的站（未示出）。然而，此能倂入或附加至集墨器 〇 擦拭器變化例 圖35至46顯示擦拭器能採用的一系列不同構造。擦 拭列印頭的噴嘴面試移除紙塵、溢出墨水、乾掉墨水、或 其他污物的有效方式。一般的工作者會瞭解，可能有無數 的不同擦拭器構造，其中多數不適合用於任何特殊的印表 機。功能性的效率（亦即清潔列印頭）必須權衡生產成本 、希望的作業壽命、尺寸及重量限制條件、和其他考量因 素。 單一接觸刮片 圖35顯示具有安裝在硬塑膠基座270內之單一彈性 體刮片2 9 0的擦拭器維護站2 6 6，使得刮片垂直於媒介饋 給方向延伸。沿著噴嘴陣列之長度延伸的單一擦拭器刮片 ’是具有低生產和組合成本的單純擦拭配置。有鑑於此， -29- 200932565 單一刮片擦拭器適合於印表機和價格範圍的底端。 生產量需要有效率的製造技術和印表機組件的簡易 此必須對單元的作業壽命、或擦拭器清潔列印頭的 效率做一些妥協折衷_。但是單一刮片設計是袖珍的 果刮片不能一次橫越中有效率地清潔噴嘴表面，則 動能簡單地重複擦拭作業，直到列印頭乾淨爲止。 多個接觸刮片 Ο 国 圖36、43A、43B、和46顯示具有多個平行刮片 拭器維護站266。在圖36中，兩個相同的平行刮片 垂直於媒介饋給方向延伸。兩個刮片292分離地安裝 塑膠基座270，以獨立地作業。在圖46中，各刮片 相同。第一和第二刮片（分別爲294和296 )具有不 度（或不同的橫截面輪廓）和硬度計値（硬度和黏彈 。可將每一刮片最佳化，以移除特殊類型的污物。但 q 刮片分離地安裝在硬塑膠基座270中，用於獨立地作 相對地，圖43 A和43B之多個刮片元件具有較小且 的刮片3

的某些區段彎曲或捲曲。在這些區段中的接觸壓力會不足 ® ，或者刮片和噴嘴面之間能沒有接觸。被分割成個別刮片 區段的擦拭器刮片，能解決此問題。每一區段能相對於其 相鄰區段而運動，所以接觸力的任何不一致性不會造成刮 片之其他區段的彎曲或捲曲。以此方式，接觸壓力被維持 在噴嘴面，且噴嘴面是乾淨的。 具有多個歪斜刮片的噴嘴面擦拭器 _ 在圖39中，擦拭器維護站266具有安裝在硬塑膠基 0 座270內的一系列獨立刮片3 08，以致該等刮片傾斜於擦 拭方向。設置各刮片3 08使得每一刮片（相對於擦拭方向 )的橫向範圍（X)和其相鄰刮片的橫向範圍（Y)有一 些重疊（Z)。藉由將擦拭器刮片安裝成歪斜於擦拭方向 ，則在擦拭器構件橫越期間的任何時間，噴嘴面只和刮片 的一個區段接觸。由於只有一個區段接觸噴嘴面，所以刮 片不會因爲沿著其整個長度的不一致接觸壓力而弄皴或捲 曲。此確保擦拭器刮片和全部的噴嘴面之間足夠的接觸壓 -32- 200932565 力，且不須對齊刮片使其精密地平行於噴嘴面。此允許寬 鬆的製造公差’以致可使用較大量的低成本生產技術。單 —歪斜刮片可達到此目的，但是會增加擦拭器構件必須行 經的距離以清潔列印頭，因此增加每一擦拭作業所需的時 間。有鑑於此’本發明使用一系列相鄰的歪斜刮片，每一 個別刮片擦拭噴嘴陣列的對應部份。在某些應用中，多個 刮片比單一刮片涉及較高的製造成本’但是袖珍設計和較 快的作業比這些潛在的缺點更重要。 〇 具有陣列墊的擦拭器 在圖40和44中，擦拭器維護站266使用陣列的接觸 墊3 1 0，而不是任何的刮片構造。個別墊3 1 2可爲個別安 裝進入硬塑膠基座270內之一組短圓柱彈性體材料、或類 似於常常使用於矽晶圓清潔用之格式的圓柱狀軟纖維刷。 如上所述，以單一長接觸表面擦拭頁寬列印頭的噴嘴表面 會無效率。擦拭表面和噴嘴面之間的不一致接觸壓力，會 〇 使接觸壓力不足或不存在某些區域內。 使用已被分割成陣列310之個別接觸墊的擦拭表面， 允許每一墊相對於相鄰墊運動，所以不一致的接觸力會改 變其量，使每一墊個別地壓縮和變形。一個墊的相對高壓 縮，不須傳輸壓縮力致其相鄰的墊。以此方式’均勻的接 觸壓力被維持在噴嘴面，且更有效率地清潔噴嘴面。 正弦刮片 -33- 200932565

使得接觸壓力更均勻，但是在每一擦拭作業中，擦拭器刮 片需要行經更長的行程。如上所述，擦拭器表面相對於噴 嘴面的不準確運動，是接觸壓力不足的來源。增加擦拭器 行程的長度，只增加此不準確的風險。 藉由使用具有角形或彎曲形的擦拭表面，使得以傾斜 於媒介饋給方向的擦拭器區段擦拭大部份的噴嘴面，同時 減少擦拭器構件相對於列印頭的行程長度。一般的工作者 會瞭解，接觸刮片可具有淺V形或U形。再者，如果刮 Q 片318的前緣是兩直線區段（或U形刮片之彎曲區段） 的交點，則申請人已發現刮片有較少的磨損，因爲對和噴 嘴面接觸的初始點提供額外的支撐。 纖維墊 圖45顯示具有安裝至硬塑膠基座270之纖維墊320 的列印頭擦拭器維護站266。纖維墊3 20用於擦拭噴嘴面 特別有效。墊呈現許多和噴嘴面接觸的點，使得纖維能機 械性嚙合固體污物，且藉由毛細作用將例如墨水溢流等流 -35- 200932565 體污物吸掉。但是，一旦纖維墊已清潔噴嘴面，則難以從 纖維墊移除污物。在很多次的擦拭作業以後，纖維墊裝滿 許多的污物，且不再有效率地清潔噴嘴面。但是就希望具 有短作業壽命的印表機或允許更換擦拭器的印表機而言， 纖維墊會提供最有效率的擦拭器。 組合式擦拭器維護站 可瞭解的是，藉由具有上述擦拭構造的組合，一些列 印頭設計會被最有效率地清潔。例如單一刮片組合一系列

INSTRUCTIONS OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to the field of printers and in particular to pagewidth inkjet printers. [Prior Art] The applicant has developed a wide range of printers for use. The page width print head is not a traditional reciprocating print head design. The page width design increases the print rate because the print head does not have to traverse the page to rewind to deposit a column of images. The page width print head simply deposits ink on the medium because it moves at high speed through the medium. These printheads have been able to perform full color 1 600 dpi printing at a rate of about 60 pages per minute, which was previously unattainable with conventional inkjet printers. A high print rate requires a large ink flow rate. Not only is the flow rate high, it is much more complicated to dispense ink along the entire length of a single wide print head than to feed a relatively small reciprocating print head. In order to extend the life of the print head, most inkjet printers are added to certain types of maintenance facilities. Covering the print head when the print head is not in use is one of the simple ways. Cap the print head so that the ink on the nozzle does not dry out. However, this does not remove paper dust or other contaminants that have adhered to the nozzle face. The most effective way is to wipe the nozzle face with a suitable surface to remove the particles. Typically, it is most effective to remove contaminants from the nozzle surface with a resilient wiping surface. However, it has been found that when the wiper-5-200932565 first contacts the nozzle face during a wiper operation, the impact of the elastomer in the surface is sufficient to cause the ink to bounce off the nozzle when the wiper When the nozzle surface is ejected, there is no contact pressure, so the nozzle surface of the portion is cleaned. SUMMARY OF THE INVENTION Accordingly, the present invention provides a printing apparatus for an ink jet printer having a print head having a nozzle face defining a row, the print head maintenance facility comprising: A wiper member is used to wipe the nozzle face; a base is used to support the wiper member; and a maintenance driver is used to selectively wipe the wiper member at different rates. With a variable speed maintenance drive, the wiper can be in contact with the nozzle face at a slower rate to avoid rebound and maintain contact. Preferably, the print head is a one-page wide print head such that the nozzle 细长 is elongated and extends over the print width of the media substrate sheet, the wiper extending over the length of the elongated nozzle array . Preferably, the maintenance drive has a first actuator for moving the wiper member toward and away from the nozzle face, and a second actuating the wiper member about an extension extending across the media feed direction, The first actuator and the second actuator are independently operable, the second actuator being configured to selectively change a rate at which the wiper is rotated about the axis extending across the media feed direction. Wipe the surface. Unable to clear the nozzle array. The rate at which the array is moved is the wiper configuration. The wiper is used to rotate the axis. Preferably the member is wound around. The -6 - 200932565 aligner and the second actuator are both electric motors having encoder discs that provide feedback to a print engine controller within the ink jet printer . Preferably, the second actuator is reversible such that the wiper member is rotatable in both directions. In a more preferred form, the first actuator is configured to apply a moving force to the base at a first support point proximate one end of the wiper member and is configured to be adjacent the wiper member A second support point at the other end applies an equal amount of moving force to the base, the first support point and the second support point being equidistant from the longitudinal intermediate point of the wiper member. Preferably, the maintenance drive has a first arm that meshes with the first support point and a second arm that engages with the second support point. The maintenance drive also has a first cam and a second cam. The first cam is engaged with the first arm and the second cam is engaged with the second arm, and the first and second cams are mounted to be rotatable on a common axis. In a more preferred form, the maintenance drive has a first actuator for rotating the base about an axis extending across the media feed direction. In a particularly preferred form, the maintenance drive has a second actuator for rotating the common shaft such that the first actuator and the second actuator are independently operable. Preferably, the wiper member has a plurality of elastic blades extending over the width of the media substrate. Preferably, the elastic blades are arranged in parallel rows, each column extending over the width of the media substrate. In a preferred form, the wipers in a column of the parallel rows are arranged such that they are not aligned with the wiper positioned in an adjacent column of the parallel rows. In a particularly preferred form, the wiper in each parallel row is spaced apart from the adjacent wiper by a gap that allows for the vertical movement of the adjacent wiper. In some embodiments, the base is a tubular base and the wiper member is mounted external to the tubular base. In some embodiments, the maintenance facility further includes an ink absorber mounted on an exterior of the tubular base. In a more preferred form, the maintenance facility further includes a capper and a printing platen mounted on the exterior of the tubular base. Preferably, the tubular base has a porous material in the central chamber and a bore for establishing fluid communication between the wiper member and the porous material. In a particularly preferred form 0, the wiper member is a molded elastic member. In a particularly preferred embodiment, the exterior of the tubular base has a plurality of mounting locations, each of which is configured to mount any of the wiper member, the ink collector and the platen. Preferably, the printhead maintenance facility further includes an absorbent pad extending over the length of the wiper member such that the maintenance drive moves the wiper member across the absorbent pad after the wiper member wipes the nozzle face 0. In some embodiments, the second actuator repeatedly moves the wiper member across the first actuator while the base is held away from the nozzle face for contact with the wiper member. Absorbing pad. Preferably, the absorbent pad has a cleaning surface that contacts the wiper member, the contact surface being covered by a woven material having a line of less than 2 denier. In a more preferred form, the woven material is a mixture of a polymer and polyamine. In a particularly preferred embodiment, the woven material is microfiber. In some embodiments, the absorbent pad has a core of foamed material. -8 - 200932565 In a more preferred form, the printhead maintenance facility further includes a doctor blade extending across the media feed direction, wherein the maintenance drive moves the wiper member to the nozzle face during use And then traversing the absorbent pad and then deflecting the elastic blade through the blade for passing the blade and when the elastic blade is disengaged from the blade, the elastic blade will spring back to its resting shape. Drop contaminants away from its surface. [Embodiment] Printer Fluid Engineering System Figure 1 is a schematic illustration of the fluid engineering used in the printing engine described in Figures 2A and 2B. As mentioned previously, the print engine has the primary mechanical construction of an inkjet printer. Construct perimeter structures (such as housings, feeder trays, paper trays, etc.) to make them suitable for printing on printers such as photo printers, network printers, or printers Claim. The applicant discloses a photo printer of USSN 11/688863 (our case number RRE 001 US) in the co-genus, which is an example of an ink jet printer using the fluid engineering system of Fig. 1. The contents of the application in the Common Commons are incorporated herein by reference. The operation of the system and its individual components are described in detail in USSN 11/872719 (our case number SBF 0 09US), the disclosure of which is incorporated herein by reference. Briefly, the printer fluid engineering system has a printhead assembly 2 that supplies ink to the printhead assembly 2 via an upstream ink line 8. The waste ink is discharged to the waste ink tank 1 via the downstream ink line. For simplicity, only a single ink line is shown. In fact, the print head has multiple -9-200932565 ink lines for full color printing. The upstream ink line 8 has a shut-off valve for selectively isolating the print head assembly 2 from the pump 12 and/or ink; Pump 1 2 is used to actively dispense or flood the printhead set 2. The pump 12 is also used to establish a negative pressure within the ink tank 4. The negative pressure is maintained by the bubble dot gauge 6 during printing. The print head assembly 2 is a liquid crystal polymer module 20 which wipes the print head integrated circuit 30 of the column; the print head integrated circuit 3 is fixed by a viscous die attach film (not) . The ink jet nozzles of the array head circuit 30 array are used to eject ink droplets to pass through the dielectric substrate 22. The nozzles are microelectromechanical constructions printed at true 1600 dpi (ie 1600 npi nozzle pitch) or greater resolution. The fabrication and construction of a suitable print head integrated circuit 30 is described in detail in US Ser. No. 1 1/246,687 (O.S. Serial No. MNN 001 US), the disclosure of which is incorporated herein by reference. The liquid crystal polymer module 20 has a main channel 24 extending between the inlet 36 and the exit pupil. The main passage 24 feeds a series of fine passages 28 that extend to the underside of the polymer module 20. The fine channel 28 supplies ink to the print head assembly 30 through the laser cut-out holes in the crystal film. Above the main channel 24 is a series of un-filled air pockets designed to be in the column A bag of air is confined during the print head. The air bag gives the system some compliance to absorb and damp high points and hydraulic shock in the ink. The printer is a high speed page wide printer with a large number of nozzles. This printer consumes ink quickly and at a glance, or even the end of a page, meaning the orientation (and the 10, can 4 fit, by a series showing the spray of the medium 1 3 8 Liquid crystal grain attached circuit 26 = These pressure shots are connected) -10- 200932565 A line of ink moving in the print head assembly 2 must be stopped almost instantaneously. If there is no compliance provided by the air pockets 26, the momentum of the ink will overflow the nozzles of the print head integrated circuit 30. Furthermore, the subsequent "reflected waves" produce a strong negative pressure sufficient to remove the nozzle. Print Engine Figure 2A shows the print engine 3 using the Print 匣2 type. The print engine 3 is the internal construction of the ink jet printer, so it does not include any outer casing, ink tank, or media feed and collection tray. The user raises or lowers the latch 1 26 to insert or remove the print head 匣2. The print engine 3 and the contacts on the print head 匣 2 form an electrical connection and are fluidly coupled by the yoke 120, the inlet manifold 48, and the outlet manifold 50, respectively. The media sheet is fed to the print engine by the main drive roller 186 and the discharge feed roller 178. The main drive roller 1 8 6 is driven by the main drive pulley and the encoder disc 1 8 8 . The discharge feed roller 177 is driven by the discharge drive pulley 180. The discharge drive pulley 180 and the main drive pulley 188 are synchronized by the medium feed belt 182'. The medium feed motor 190 supplies power to the main drive pulley 188 via the input drive belt 192. The main drive pulley 188 has an encoder disc and the drive pulley sensor 184 reads the encoder disc. Information on the number of revolutions and the speed of the drive shafts 186, 178 is sent to the print engine controller (PEC). A print engine controller (not shown) is mounted to the main printed circuit board (PCB) 194' and is the primary microprocessor for controlling printer operation. Figure 2B shows the print engine 3' after the print head has been removed to reveal the holes 122 in each of the sockets -11 - 200932565. Each aperture 122 houses one of the nozzles 52 on the inlet manifold manifold (see Figure 5). As noted above, the ink has any position and configuration, but is simply attached to the hollow insertion opening 124 at the rear of the inlet affinity holder 120 (see Figure 8). The insertion opening 124' at the rear of the outlet is connected to the waste ink tank (see the waste ink outlet of Fig. 1. The reinforcing support surface 128 is fixed to the pressurized gold body 96 of the printing engine 3. These are provided for printing The head lice are set in the print engine test points. They are also set to provide the opposite bearing surface for the load acting on 匣 2 during installation. When the manifold nozzle (described below) prints off the valve in the engine ( When the following), the fluid coupler 120 pushes against the inlet manifold and the outlet manifold. The pressure of the latch 126 on the crucible 2 is also opposite to the bearing surface 128. The bearing surface 128 is disposed such that it directly opposes the compressive load in 2, It can reduce the bending and deformation in the crucible. Finally, the aid nozzle is positioned relative to the medium feed path. It also protects the weaker mechanism from damage. Print head Figure 3 is the complete print head匣2 perspective view. Print head 匣 2 top module 44 and removable protective cover 42. Top module 44 has a middle plate for constructive stiffness and is used to provide a textured clamping surface 58 during insertion and Manipulating the 匣 during removal. Before installing in the printer 'hood The bottom of the 42 protects the print head integrated circuit (not shown) and the entire column. The cover 56 is formed at the bottom and covers the ink inlet and the inlet and outlet tanks.匣 匣 匣 帮 帮 帮 帮 帮 帮 帮 帮 帮 帮 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 , , , , , , , , Figure 4 shows the printhead assembly 2' with the protective cover 42 removed to expose the printhead integrated circuit on the bottom surface and the entire array of contacts 33 on the side surfaces. Throw the protective cover to the recycling waste or assemble the protective cover to the replaced print head to cover the leakage of residual ink. Figure 5 is a partially exploded perspective view of the print head assembly 2. The top cover has been removed to reveal the inlet manifold 48 and the outlet manifold 50, and the inlet and outlet panels 46, 47 have been removed to more clearly expose the five inlet nozzles 52 and the five outlet nozzles 54. The inlet and outlet manifolds 48, 50 form a fluid connection between each individual inlet and outlet and the main channel within the liquid crystal polymer (see Figure 24). The main channel extends the length of the liquid crystal polymer and the main channel feeds a series of fine channels on the underside of the liquid crystal polymer module. An array of air pockets 26 are formed above each of the main passages 24. The shock wave or pressure pulse in the ink is damped by compressing air in the air pocket 26 as described above with respect to Figure 1. Figure 6 is an exploded perspective view of the print head assembly without the inlet or outlet manifold or cap module. The primary channel 24 for each ink pigment and its associated air pockets 26 are formed in the channel module 68 and the pocket module 72, respectively. The die attach film 6 6 is bonded to the bottom of the channel module 68. The die attach film 66 mounts the print head integrated circuit 3〇 to the channel module such that the thin channel on the lower side of the channel module 经由 8 passes through the small laser cut-out hole through the film and the print head integrated circuit 30 is in fluid communication. Because of the stiffness and thermal expansion coefficient of the liquid crystal polymer, both the channel module 68 and the top cover module 72 are molded by a liquid crystal polymer, and the thermal expansion coefficient of the liquid crystal polymer and the thermal expansion coefficient of the liquid crystal polymer. Closely -13 - 200932565 matches. It will be appreciated that the relatively long configuration of, e.g., a pagewidth printhead, should minimize any differences in thermal expansion between the tantalum substrate of the printhead integrated circuit 30 and its support structure. Printhead Maintenance Dial Refer to Figure 7' for a cross-sectional perspective view. This profile is through line 7-7 shown in Figure 2A. The print head cartridge 2 is inserted into the print engine 3 such that its outlet manifold 50 is in fluid communication with the insertion port 124, which guides the waste ink canister into the finished product of the printer (usually located on the base of the print engine) ). The liquid crystal polymer module 20 supports the print head integrated circuit 3 〇 next to the medium feed path 22 extending through the print engine. The printhead maintenance carousel 150 and its associated drive mechanism are located on opposite sides of the media feed path 22. The printhead maintenance dial 50 is used for rotation about the tubular drive shaft 156, which is also configured to move toward and away from the printblock integrated circuit 30. By raising the dial 150 to the head integrated circuit 30, various print head maintenance stations on the exterior of the turn are presented to the print head. The maintenance carousel 150 is rotatably mounted on the lift configuration 170 that is mounted to the lift configuration shaft 156 so that it can pivot relative to the rest of the configuration of the print engine 3. The lift configuration 70 includes a pair of lift arms 158 (only one lift arm is shown and the other lift arm is disposed at the opposite end of the lift build shaft 156). Each lift arm 158 has a cam engaging surface 168' such as a low friction material roll or pad. A cam (described in detail below) is secured to the turntable drive shaft 160 for rotation with the shaft 160. The lift arm 158 is biased into engagement with a cam on the turntable lift drive shaft 16b, -14-200932565 enabling the turntable lift motor (described below) to move the turntable toward and away from the print by rotating the shaft 160 head. The rotation of the maintenance turntable 150 about the tubular shaft 166 is driven independently of the turntable lift. The turntable drive shaft 166 engages the turntable rotary motor (described below) so that it can be rotated regardless of whether it is retracted from the print head or toward the print head. When the turntable is advanced toward the print head, the wiper blade 1 6 2 moves through the medium feed path 22 to wipe the print head integrated circuit 30. When the turntable 150 is withdrawn from the print head, the turntable 150 is repeatedly rotated such that the wiper blade 162 chews the doctor blade 154 and the cleaning pad 152. This is also discussed in detail below. Referring now to Figure 8, sections 7-7 are shown in plan view to more clearly describe the maintenance dial lift drive. The turntable lift drive shaft 160 is shown rotated such that the lift cam 172 pushes the lift arm 158 downward by the cam engagement surface 168. The lift shaft 160 is driven by a turn-up spur gear 174 which is sequentially driven by the turn-up worm gear 176. The worm gear 17 is fixed by a key to the output shaft of the turntable lift motor (described below). As the lift arm 158 pulls the lift configuration 170 down, the maintenance carousel 150 is withdrawn from the printhead integrated circuit 30. In this position, when the turntable 50 is rotated, no maintenance station contacts the print head integrated circuit 30. However, the turntable will drive the wiper blade 162 into contact with the doctor blade 154 and the absorbent cleaning pad 152. Tongue [doctor blade -15- 200932565 The scraper 154 works in conjunction with the cleaning pad 152 to extensively clean the wiper blade 162. The cleaning pad 152 wipes the paper dust and the dried ink from the wiping contact surface of the wiper blade 162. However, small ink beads and dirt can form the tip of the blade 162 that does not contact the surface of the cleaning pad 152. In order to remove this ink and dust, the blade 1 54 is mounted in the printing engine 3' to contact the blade 154 after the blade 1 62 wipes the head integrated circuit 30 but before contacting the cleaning pad 152 162. When the wiper blade 1 62 contacts the blade 1 54 , the wiper blade 1 62 is flexed into an arc for passage. Because the wiper blade 162 is an elastomeric material, as soon as it is disengaged from the blade 154, it springs back to its stationary straight shape. Quickly bounces back to its still shape, projecting dust and other contaminants from the wiper blade 162 (especially from the tip). Conventional workers will appreciate that the wiper blade 162 will also flex when it contacts the cleaning pad 152 and will again bounce back to its resting shape once the wiper blade 162 is released from the pad. However, the scraper 154 is radially mounted closer to the center shaft 166 of the turntable 150 and further away from the cleaning pad 152. This configuration makes it more curved when the wiper blade 162 passes, and gives more momentum to the dirt when it bounces back to a stationary shape. Since the cleaning pad 152 contacts the leading blade so that the trailing blade is improperly wiped past the cleaning pad 152, it is not possible to simply move the cleaning pad 152 closer to the carousel shaft 166 to make the wiper blade 162 more curved. Cleaning Pad The cleaning pad 152 is an absorbent foam that is formed into an arc corresponding to the circular path of the wiper blade 162 of -16-200932565. When the pad 152 is covered with a woven material to provide a plurality of dense gathered contact points when wiping the blade, the pad 152 is more efficiently cleaned. Therefore, the size of the thread of the woven material should be relatively small, for example less than 2 denier. Microfiber materials with a wire size of about 1 denier work particularly well. The cleaning pad 152 extends the length of the wiper blade 162 and the wiper blade 162 also extends the length of the page width printhead. The page width cleaning pad 152 simultaneously cleans the entire length of the wiper blade, which reduces the time required for each wiping operation. Moreover, the length of the page wide cleaning pad inherently provides a large volume of absorbent material for holding a relatively large amount of ink. Because of the greater ink absorption capacity, it is less necessary to replace the cleaning pad 152 frequently. Capping on the Print Head Figure 9 shows the first stage of the capped print head integrated circuit 30 with the capped maintenance station 198 mounted to the maintenance carousel 150. When the lift cam 172 is pushed down on the lift arm 158, the maintenance dial 150 is withdrawn from the print head integrated circuit 30. The maintenance carousel 150 is rotated along with the maintenance encoder disk 204 until the first carousel rotation sensor 200 and the second carousel rotation sensor 202 determine that the print head capper is facing the print head integrated circuit 3 0 . As shown in Fig. 10, the lift shaft 160 rotates the cam 172 such that the lift arm 158 moves upward to advance the maintenance dial 150 toward the print head integrated circuit 30. The capper maintenance station 198 engages the underside of the liquid crystal polymer module 20 to seal the nozzles of the printhead integrated circuit 30 in a relatively humid environment. Ordinary workers will understand that this prevents (at least prolonged) nozzles from -17-200932565 to dry and block. Removing the Print Head Cover Figure 11 shows the print head integrated circuit 30 with the cover removed to prepare for printing. The lift shaft 160 is rotated such that the lift cam 172 pushes the turn arm lift arm 158 downward. The capping maintenance station 1 98 moves away from the liquid crystal polymer module 20 to expose the print head integrated circuit 30. Wiping the print head Fig. 12 shows the print head integrated circuit 30 being wiped by the wiper blade 162. When the capping station 198 is rotated away from the printhead, the wiper blade 162 of the wiper member contacts the underside of the liquid crystal polymer module 20. When the turntable 150 continues to rotate, the wiper blade is pulled through the nozzle face of the printhead integrated circuit 30 to wipe off any paper dust, dry ink, or other contaminants. The wiper blades 1 62 are formed of an elastomeric material so that they flex elastically and flex as they wipe through the printhead integrated circuit. When the tip end of each wiper blade is bent, the side surface of each blade forms a wiping contact with the nozzle face. It can be understood that the broad flat side surface of the blade has a large contact with the nozzle face and the dirt is removed more efficiently. Wiper Blade Cleaning (Cleaning) Figures 13 and 14 show the wiper blade 162 being cleaned. As shown in Fig. I3, after the wiper blade 162 wipes the print head integrated circuit 30, the wiper blade 162 is immediately rotated through the doctor blade 154. The work of the scraper 154 -18- 200932565 can be discussed in more detail in the title "Scraper" above. After the wiper blade 162 is pulled past the doctor blade 154, any residual dust and dirt adhering to the blade is removed by the absorbent cleaning pad 152. This step is shown in Figure 14. During this process, the print platen maintenance station 206 is just opposite the print head integrated circuit 30. If desired, the turntable can be lifted by rotating the lift cam 172 so that the nozzle can be launched into the absorbent material 208. Any pigment mixed in the ink nozzle is immediately purified. A hole (not shown) that is drilled into the side of the tubular base 166 provides fluid communication between the absorbent material 208 and the porous material 210 within the central pocket of the rotary shaft 166. The ink absorbed by the material 208 is drawn into the porous material 210 and held by the porous material 210. In order to allow the porous material 210 to drain, the turntable 150 may be provided with a vacuum attachment point (not shown) to drain the waste ink. The turntable 150 continues to rotate with a clean wiper blade (see Fig. 15)' until the print platen 206 is again positioned opposite the printhead integrated circuit 30. Then, as shown in Fig. 16, the turntable is raised toward the print head integrated circuit 30 to prepare for printing. The media substrate sheet is fed along the medium feed path 22 and passed through the print head integrated circuit 30. In the case of full bleed (printed to the extreme side of the media sheet), the media substrate can remain away from the platen 206' so that it does not become soiled by excessive ink spray. It can be appreciated that the 'absorbent material 208 is disposed within the recessed portion of the printing platen 206 such that any oversprayed ink (typically about 1 mm on both sides of the paper) is held away from the contactable media substrate. s surface. At the end of the printing job or before the printer will enter the standby mode, the -19-200932565 turntable 1 50 is withdrawn from the printhead integrated circuit 30 during rotation, so that the printhead capping maintenance station 1 98 is rendered again To the print head. As shown in Fig. 17, the lift shaft 160 rotates the lift cam 158 such that the lift cam 158 moves the print head capping maintenance station into sealing engagement with the lower side of the liquid crystal polymer module 20. Printhead Maintenance Dial Figure 18, 19, 20, and 21 show the isolated maintenance dial. Figure 18 is a perspective view showing the wiper blade 162 and the print platen 206. Figure 19 is a perspective view showing the print head capper 1 98 and the wiper blade 1 62. Figure 20 is an exploded view showing the components of the maintenance carousel. Figure 21 is a cross-sectional view showing the components after the complete combination. The maintenance carousel has four printhead maintenance stations: a print platen 206, a wiper member 162, and a spreader/ink absorber 220. Each maintenance station is mounted to its own external base assembly. The outer base assembly is mounted about the turntable tubular shaft 166 and engages one another to lock onto the shaft. At one end of the tubular shaft 166 is a turntable encoder disc 204 and a turntable spur gear 212'. The turntable spur gear 212 is driven by a turntable rotary motor (not shown) as described below. The tubular shaft is fixed to or rotates with the spur gear. Each of the printhead maintenance stations rotates with the tubular shaft by virtue of its firm compression and clamping on the outside of the shaft. The wiper blade outer base assembly 2 1 4 is an aluminum extruded product (or other suitable alloy) 'constructing the wiper blade outer base assembly 2 1 4 to securely hold the wiper blade 1 6 2 . Similarly, other external base assemblies are gold -20-200932565 extrudates' softer elastomers and/or absorbent porous materials for securely mounting individual maintenance stations. The outer base assembly for printing platen 2 16 and printhead capper 198 has a series of identical locking ears 22 6 along each longitudinal edge. The wiper member outer base assembly 214 and the ink collector/ink extractor outer base assembly 218 have complementary latch-type slots for receiving the locking ears 226. Each of the card slot has an ear access opening 228 that abuts the ear lock slot 230. The locking ears 226 are inserted into the ear access holes 228 adjacent the outer base assembly and then longitudinally slid relative to each other to lock them to the base tubular shaft 166. In order to improve the friction and locking engagement between each of the maintenance stations and the base plate shaft 166, each of the printhead maintenance stations is provided with an element having an arcuate shaft engagement surface 234 formed on one side thereof. The ink collector/ink extractor outer base assembly 2 1 8 has a relatively large absorbent ink collector/ink extractor member 220 that also has an arcuate shaft engaging surface 23 4 formed on its inner face. Similarly, the common base assembly for the print head capper 1 98 and the common base of each wiper wiper blade 162 have a curved shaft engagement surface 234. The average worker will understand that using an interlocking configuration to clamp the outer base to the inner base minimizes machining and assembly time and maintains small tolerances for precise installation of the maintenance station configuration. In this case, the external base components can be combined into different configurations. Can change the wiper blade outer base assembly 2 1 4 and the ink collector/ink extractor base assembly 2 1 8 position. Similarly, the print head capper 198 and the print platen 206 can be exchanged. In this way, the maintenance stations can be combined in the best way they are installed in a special printer. -21 - 200932565 Injection Molding Polymer Carousel Base Figures 22 through 28 show a printhead maintenance carousel of another embodiment. These figures are schematic sections showing only the portion of the turntable and the print head. The 7H' maintenance drive system that should be understood requires a simple and straightforward modification to accommodate the turntable of this embodiment. Figure 2 2 shows the liquid crystal polymer module of the print head 匣2 of the print head maintenance switch i 5 ' 2 'The turntable 1 50 is presented to the print head integrated circuit by the print platen 2 0 6 30. For the sake of clarity, Figure 29 shows the printing platen 2 6 6 in isolation. In use, a sheet-like medium substrate is fed along the medium feed path 2 2 . Between the nozzle of the print head integration circuit 30 and the medium feed path 2 2 is a printing gap 2 4 4 . In order to maintain print quality, the gap 244 between the nozzle face of the print head IC circuit and the media surface should be as close as possible to the nominal 値 defined during design. In a commercially available printer, this gap is approximately 2 mm. However, because of the advancement of printing technology, some printers have a printing gap of about 1 mm. With the popularity of digital photography, the need for full-page bleeding printing of color images is growing. "Full Version Bleed Print" is the extreme edge printed to the media surface. This often results in some "over-spraying", in which the ejected ink is not sprayed on the edge of the media substrate and deposited on the support printing platen. Then, the ink that has been sprayed across the boundary will stain on the subsequent sheet medium. The configuration shown in Figure 22 handles these two issues. A paper guide 23 8 on the liquid crystal polymer module 20 defines a printing gap 244 during printing. However, the print platen 206 has a guide -22-200932565 surface 246 formed on its rigid plastic base module. The leading surface 246 directs the leading edge of the sheet toward the discharge drive roller or other drive mechanism. Because of the minimal contact between the sheet media and the print platen 206, the likelihood of soiling by the ink that has been sprayed across the boundary during full-scale bleeding printing is greatly reduced. Further, the paper guiding member 23 8 on the liquid crystal polymer module 20 is disposed in close proximity to the print head integrated circuit 30 to accurately maintain the gap 244 between the nozzle and the medium surface. Some printers within the applicant's scope use this technique to provide a 0.7 mm print gap 244. However, by making the beads of the capsular material 240 adjacent to the print head integrated circuit 30 flat, the gap can be reduced. Power and data are transferred to the printhead integrated circuit 30 by a flexible printed circuit board 242 mounted to the outside of the liquid crystal polymer module 20. The contacts of the flexible printed circuit board 2 42 are electrically connected to the contacts of the print head integrated circuit 30 by a row of lead frames (not shown). To protect the leadframe, the leadframe is wrapped in an epoxy material called a bladder. Applicants have developed a variety of techniques for flattening the outline of the leadframe and the beaded bladder 240 that covers the leadframe. This allows the printing gap to be further reduced 2 4 4 〇 The printing platen 206 has a recess or central recess 248 that faces the nozzle of the printhead integrated circuit 30. Any ink that is sprayed across the boundary will be in this area of the platen 206. The depression is formed in this area away from the rest of the platen' to ensure that the media substrate is not soiled by the wet, cross-over ink. The surface of the central pocket 248 is in fluid communication with the absorbent fibrous element 250. The fibrous element 250 and the porous material 254 in the center of the base 236 are also in fluid communication by the capillary 252. The ink that has been sprayed across the boundary is drawn into the fiber -23-200932565 element 250 and is drawn by capillary action through tube 252. Figure 23 shows the rotation of the turntable 150 for printing: now to the print head integrated circuit 30. Figure 30 shows the isolation 272 and its structural features. The print head station has an elastomeric skirt 256 having a circumference 258 that is formed from a porous material shape and a contact pad to be rigidly mounted to the rigid polymer-based polymer base 260 to the exit shape when the column is replaced When the print head 匣 2, it needs to be noted that the injection process is wasteful because the ink is usually forced to bleed any bubbles around the entire print head construction. A number of conduits of the printhead have been wasted during the removal of air. To solve this problem, the maintenance dial 150 258 is raised to cover the nozzles of the printhead integrated circuit 30. When the nozzle array is in place, the contact pad 25 8 is held against the nozzle, which is greater than the ink level of the nozzle. The porous material partially blocks the jet. However, the restriction of the air flow from the nozzle is not due to the porous material. The elastomeric skirt 256 sealingly abuts the liquid crystal polymer to draw the flow holes 264 in the excess ink polymer susceptor 260 flowing from the underside of the contact pad 258, allowing the water and any excess ink to flow to the absorption The fiber element platen 206 is the same as used. Just like printing the platen into the porous material 254, the print head station of the head station 262 is wound around the contact pad. Elastomeric skirt seat 260 from the base, 236 IJ base. ink. It is well known to pass through the nozzle until the flow is reduced by a very large amount of ink extending from the column, so that the injection contact pad reduces the flow of the discharge nozzle under pressure to limit the amount of ink, so that the entire flow is hindered and the module 22 is retarded. Side water. The ink formed in the rigid 塾 258 absorbing ink 25 0 (and the print 206, the fiber element - 24 - 200932565 250 is drawn into the porous material 254 in the shaped base 236 by the capillary 252. By using the print Head 塡 2 2 2, greatly reducing the amount of wasted ink. If there is no injection station, when the page is wide, the amount of ink wasted by each pigment is usually about 2 ml; At the station 262, the amount of ink wasted by each pigment was reduced to about 0.1 ml. The contact pad 258 need not be formed of a porous material, but instead may be formed of the same elastic material as the skirt 256. In this case, contact The pad 258 〇 needs to have a special surface roughness. The surface of the nozzle face of the mating print head integrated circuit 3 should be 2 to 4 micrometers of roughness, but smooth and smooth on the 20 micron scale. This type of surface The roughness allows air to escape from between the nozzle face and the contact pad, but only a small amount of ink escapes. Figure 24 shows the wipe station 266 of the maintenance carousel 150 presented to the printhead integrated circuit 30. The wipe station is shown independently In Fig. 31, the wiping station 266 is also a co-molded construction having a soft elastomer wiping blade 268 supported on a hard plastic base 270. To wipe the nozzle face of the printhead integrated circuit 30, the turntable base 23 6 is raised and then rotated, so wiper blade 268 is wiped over the nozzle face. Typically, turntable base 236 is rotated such that wiper blade 268 is wiped toward the capsular bead. As in the applicant's common genus file number RRE015US The discussion of the application (into the cross-reference) can be designed to help the dust and dirt get stuck on the face of the wiper blade 268. But if it proves to wipe in both directions More efficiently, the maintenance drive (not shown) can be easily constructed to rotate the base 236 in both directions. Similarly, it is easy to change the wipe through the column by changing the number of rotations -25 - 200932565 The number of times of the integrated circuit 30. The program maintains the drive to perform each wiping operation. The print head capper 272 showing the maintenance dial 150 is presented to the print head integrated circuit 30 in Fig. 25. Ground The applicator is shown to more clearly illustrate its construction. The capper 272 has a peripheral seal 274 formed of a soft elastomeric material. The surrounding seal 274 is co-molded with its hard plastic base 276. When the printer is idle, The print head capper 272 reduces the rate at which the nozzles are dried. The seal between the peripheral seal 2 74 and the underside of the liquid crystal polymer module 20 does not need to be completely airtight because the capper is being used for suction. Note the print head. In fact, the hard plastic base 276 should include an air respirator hole 278 so that the nozzle does not overflow due to the suction caused by removing the cover of the print head. To cover the print head, rotate The base 23 6 is presented to the printhead integrated circuit 30 until the printhead capper 272. The base 236 is then raised until the surrounding seal 274 engages the print head 匣2. Figure 26 shows a wiper blade cleaning pad 152 included. As described in the first embodiment above, the cleaning pad 152 is mounted within the printer such that as the maintenance dial 150 rotates, the wiper blade 268 moves past the surface of the pad 152. By providing the position of the cleaning pad 152, the base 23 must be retracted from the printhead integrated circuit 30 to allow the wiper blade 26 8 to contact the cleaning pad and to rotate the chassis 236 at a relatively high speed for a wide range. The wiper blade 2 6 8 is cleaned without any damaging contact with the print head integrated circuit 30. Further, the cleaning pad 15 2 can be wetted with an surfactant to more easily remove dirt from the surface of the wiper blade. Figure 27 shows the injection molding base 23 6 independently. The base is symmetrical with respect to the two planes extending through the central longitudinal axis 282 through -26-200932565. This symmetry is important because if the injection molding base 236 extending along the length of the page width print head is asymmetrical, it tends to be deformed and bent as it cools. Because of the symmetrical profile, the contraction is also symmetrical when the base is cooled. The base 236 has four maintenance station mounting brackets 276 formed on its outer surface, all of which are identical so that they can accommodate any of the various maintenance stations 206, 266, 262, 272. In this way, each maintenance station becomes an interchangeable module and the order in which each maintenance station is presented to the print head can be changed to suit different printers. Furthermore, if the maintenance stations themselves are modified, their standard seats ensure that the maintenance station can easily enter the existing production line with minimal equipment replacement. The maintenance station is fixed in the socket with an adhesive, but other methods (such as ultrasonic point welding or mechanical mutual engagement) are also suitable. As shown in Figure 28, the mold is provided with four sliders 278 and a central core 288. Each slider 278 has a cylindrical configuration 280 to form a conduit that connects the fiber core pad to the porous material 219 within the central pocket. The pull lead for each slider is radially outward from the base 236, while the core 28 8 is longitudinally retracted (it is understood that the core is not a precision cylinder, but a truncated cone to provide Required ventilation). Injection molding of polymer components is well suited for large and low cost production. Furthermore, the symmetrical construction and uniform shrinkage of the base maintains good tolerances to maintain the maintenance station extending parallel to the printhead integrated circuit. However, other manufacturing techniques are also possible, such as shock waves of compressed polymer powder or the like. Furthermore, the increased hydrophilicity of -27-200932565 surface treatment' can help the ink flow to the capillary 252 and ultimately to the porous material 210 within the base 236. In some printer designs, a base is constructed for connecting a vacuum source to periodically discharge ink from the porous material 210. Five Maintenance Station Embodiments FIG. 34 shows an embodiment of a printhead maintenance carousel 150 having five A different maintenance station: print platen 2 06, print head wiper 2 6 6 , print head capper 272, picking station 262, and ink collector 284. The ink collector 284 (shown separately in Figure 33) has a relatively simple construction ___The ink collector face 2 84 presents a flat to print head ' and has holes (not shown) for retention and retention in its plastic base The fiber elements 250 are in fluid communication. A five-station maintenance carousel 150 is attached to an ink collector 284 to allow the printer to use the primary ink purge as part of the maintenance system. The four-station turntable of Figure 22-25 uses the print platen 2 0 6 and/or the capper 2 7 2 to provide a secondary ink purge or "spitting cycle". During the printing operation, a secondary discharge cycle is used after the nozzle face is wiped or when inter-page spit is used to keep the nozzle moist. However, if the print head needs to be recovered from removal of the sputum, severe pigment mixing, large size nozzles, etc., a major discharge cycle may be required - because the condition has exceeded the capacity of the platen or capper. The ink collector 284 has a large aperture or series of retaining ribs in its face 286 to retain the fibrous core material 250 within the plastic base. This keeps the fiber element 250 very open to potential ink intensive spraying. One face of fiber element -28-200932565 250 is pressed against capillary 252 to increase the flow of porous material 254 into the central pocket of base 236. The five-seat base 236 is injection-molded using five sliders that are 72 degrees from each other or six sliders that are 60 degrees from each other. Similarly, a maintenance carousel with more than five stations is also possible. If the nozzle face has a tendency to gather away from the ink, it is still difficult to remove using the wiper alone. In these cases, the printer may require a station (not shown) for ejecting ink solvent or other cleaning fluid onto the nozzle face. However, this can be incorporated or attached to the ink collector. 擦拭 Wiper variants Figures 35 through 46 show a range of different configurations that the wiper can take. Wipe the nozzle of the print head to interview an effective way to remove paper dust, spill ink, dry ink, or other contaminants. The average worker will understand that there may be countless different wiper configurations, many of which are not suitable for any particular printer. Functional efficiency (ie, cleaning the print head) must weigh production costs, desired operating life, size and weight constraints, and other considerations. Single Contact Blade Figure 35 shows a wiper maintenance station 266 with a single elastomer blade 290 mounted within a hard plastic base 270 such that the blade extends perpendicular to the media feed direction. A single wiper blade' that extends along the length of the nozzle array is a simple wiping configuration with low production and assembly costs. With this in mind, the -29- 200932565 single wiper wiper is suitable for the bottom of the printer and price range. Production requires efficient manufacturing techniques and the simplicity of the printer components. This must compromise some of the unit's operational life, or the efficiency of the wiper cleaning the printheads. However, the single blade design is a small-sized fruit blade that cannot effectively clean the nozzle surface in one traverse, and the kinetic energy simply repeats the wiping operation until the print head is clean. Multiple Contact Blades Figures 36, 43A, 43B, and 46 show a plurality of parallel wiper maintenance stations 266. In Figure 36, two identical parallel blades extend perpendicular to the media feed direction. Two blades 292 are separately mounted to the plastic base 270 to operate independently. In Fig. 46, each blade is the same. The first and second wipers (294 and 296, respectively) have inferior (or different cross-sectional profiles) and hardness gauges (hardness and viscoelastics. Each wiper can be optimized to remove special types) But the wiper blades are separately mounted in the hard plastic base 270 for independent relative orientation, and the plurality of wiper elements of Figures 43A and 43B have smaller and smaller wipers 3 00, all of which A common elastomeric base 29 8 is mounted, and the body base 298 is fixed to the hard plastic base 270. This is a substantially more sturdy construction. It has a relatively large surface area in the wiper. The nozzle face is thin and soft. The blade is relatively large and the sturdy blade wears out quickly. As a plurality of parallel blades wipe the nozzle surface, the wiper member converges more dust and dirt at a time. Although the design of the multiple blades is high. The rate and the 292 to hard and different widths of the escort are all kinds of industries. Shorter the bomb should be. However, the rate is more than single -30- 200932565. A scraper is less pocket-sized, but each wipe is faster and more. Before the print job, the print head print can be wiped between pages. Initial maintenance performed, a single skew blade in a short time Figure 37 shows a wiper maintenance station 270 having a 302 mounted on a hard plastic base 270 such that the wiper 302 is skewed relative to it. It can be understood that the wiping direction extends perpendicularly to the plastic base. A single wiper blade is a configuration with low production and assembly costs. Further, the nozzle face is only in contact with the blade segment by mounting the blade to be skewed at any time during which the wiper member is traversed. Since only one section contacts the nozzle face, the scraping is an inconsistent contact pressure along its entire length to smear or enclose a sufficient contact pressure between the wiper blade and all of the nozzle faces to precisely align the wiper to Fully parallel to the nozzle face. This allows manufacturing tolerances so that a larger amount of low cost production techniques can be used to increase the distance that the wiper member must travel to clean the print head compromise. Increasing this distance therefore reduces the manufacturing cost required for each wiping operation than these potential drawbacks. Separate Contact Blade Figure 38 shows a wiper maintenance station 266 having a wiper blade 304 mounted within a hard plastic base 270. Every individual efficiency. Because; and in the column is completed. Single wiper Wipe the direction of the 270. Simple wipe, the area of the wipe will not be affected. This is true and not allowed to be loose. This must be done properly. However, the two segmented blade segments -31 - 200932565 3 06 constitute a complete blade 304 mounted in the hard plastic base 270 for independent movement relative to each other. The individual wiper segments 306 in each wiper 310 are placed out of alignment with respect to the wiping direction. In this manner, the nozzles that are not wiped by the first wiper 3 0 4 in the gap between the two wiper segments 306 are wiped by the wiper segments 306 in the second wiper 34. It is inefficient to wipe the nozzle face of the page wide print head with a single long wiper. Inconsistent contact pressure between the wiper blade and the nozzle face can cause the blade to bend or curl along certain sections of its length. The contact pressure in these sections will be less than ® or there will be no contact between the wiper and the nozzle face. A wiper blade that is divided into individual wiper segments can solve this problem. Each segment can move relative to its adjacent segment so that any inconsistency in contact forces does not cause bending or curling of other segments of the blade. In this way, the contact pressure is maintained on the nozzle face and the nozzle face is clean. Nozzle Face Wiper with Multiple Skew Blades - In Figure 39, the wiper maintenance station 266 has a series of individual wipers 308 mounted within a hard plastic base 0 270 such that the wipers are inclined to the wiping direction . Each of the blades 308 is disposed such that the lateral extent (X) of each blade (relative to the wiping direction) and the lateral extent (Y) of its adjacent blade overlap (Z). By mounting the wiper blade to be skewed in the wiping direction, the nozzle face is only in contact with a section of the blade at any time during the traversal of the wiper member. Since only one section contacts the nozzle face, the wiper does not smash or curl due to inconsistent contact pressure along its entire length. This ensures a sufficient contact pressure between the wiper blade and the entire nozzle face -32-200932565 force without the need to align the wiper so that it is precisely parallel to the nozzle face. This allows for loose manufacturing tolerances so that larger quantities of low cost production techniques can be used. A single-slanted blade can do this, but it increases the distance that the wiper member must travel to clean the printhead, thus increasing the time required for each wipe. In view of the present invention, a series of adjacent skew blades are used, each of which wipes a corresponding portion of the nozzle array. In some applications, multiple wipers involve higher manufacturing costs than a single wiper's but pocket design and faster work are more important than these potential drawbacks.擦拭 Wiper with Array Pad In Figures 40 and 44, the wiper maintenance station 266 uses the array of contact pads 310, rather than any blade configuration. The individual pads 3 1 2 can be individually mounted into a set of short cylindrical elastomeric materials in the hard plastic base 270, or a cylindrical soft fiber brush similar to that commonly used in the cleaning of wafers. As described above, it is inefficient to wipe the nozzle surface of the page wide print head with a single long contact surface. Inconsistent contact pressure between the wiping surface and the nozzle face may result in insufficient or no contact pressure in certain areas. The use of a wiping surface that has been divided into individual contact pads of array 310 allows each pad to move relative to the adjacent pad, so that inconsistent contact forces can change its amount, causing each pad to compress and deform individually. The relative high pressure of a pad does not require the transmission of compressive forces to cause adjacent pads. In this way, the uniform contact pressure is maintained on the nozzle face, and the nozzle face is more efficiently cleaned. Sinusoidal Blade -33- 200932565 In the wiping maintenance station 266 shown in Fig. 41, the hard plastic base 270 is simply inserted so that the blade follows the sinusoidal path, and the nozzle of the page wide print head is wiped with a single long contact surface. Inconsistent contact pressure between the wiping surface and the nozzle face is insufficient or does not exist in certain areas. The contact pressure may change. The reason is that the wiper surface is inaccurate with respect to the nozzle face. In the entire stroke length during the wiping operation, the area for low contact pressure is cleaned locally for wiping the surface not completely parallel to the nozzle face. The above problem can be avoided as if the position of the associated wiper blade of the skewed mounting blade is set to be inclined with respect to the feeding wiping direction. In this way, at any time, only a portion of the wiper blade contacts a small angle between the spray blade and the wiping direction, improving the wiping. When the wiper moves obliquely over the nozzle face, the wiper points more points of contact for better dirt removal. This changes any problems caused by contact pressure, but the wiper blade travels a longer stroke for each wipe. As described above, the inaccurate movement of the nozzle face is insufficient for the length of the contact presser wiper stroke, which is disadvantageous for the pocket design. Wipe the nozzle face using a wiper blade with a zigzag or sinusoidal shape to feed the plurality of wiper segments in the direction. The stroke length of the wiper member relative to the print head is small and compact. A blade 3 1 4 is safe. As mentioned earlier, there will be no efficiency, which will make one of the movements of contact compression. If the support area on the surface may not be adequate, use the wipe and print head to spray the surface of the job. In addition, the cleaning and efficiency are inconsistent with the nozzle face. The source of the surface force of the wiper is required during the wiping operation. Increasingly, the configuration is also sufficient to maintain accuracy. -34-200932565 Single wiper blade having a non-linear contact surface. Figure 42 shows a wiper maintenance station 266 having two linear segments at an angle to each other and skewed in the wiping direction. Mounted on a hard plastic base 270. Wiping the nozzle face of the page wide print head with a single long contact surface as described in U can cause insufficient or no contact pressure in certain areas. Having the blade angled relative to the wiping direction and the printhead nozzle face means that only a portion of the wiper blade contacts the nozzle face at any time during the wiping operation. This makes the contact pressure more uniform, but in each wiping operation, the wiper blade needs to travel longer. As noted above, the inaccurate movement of the wiper surface relative to the nozzle face is a source of insufficient contact pressure. Increasing the length of the wiper stroke only increases the risk of this inaccuracy. By using a wiping surface having an angular or curved shape, the wiper section inclined in the direction of the medium feed is wiped over most of the nozzle face while reducing the stroke length of the wiper member relative to the printhead. A general worker will appreciate that the contact blade can have a shallow V or U shape. Furthermore, if the leading edge of the wiper Q piece 318 is the intersection of two straight sections (or curved sections of a U-shaped wiper), the Applicant has found that the wiper has less wear because of contact with the nozzle face. The initial point provides additional support. Fiber Mat Figure 45 shows a printhead wiper maintenance station 266 having a fiber mat 320 mounted to a hard plastic base 270. The fiber mat 3 20 is particularly effective for wiping the nozzle face. The mat presents a plurality of points in contact with the nozzle face such that the fibers mechanically engage the solid soil and absorbs, for example, ink overflows, such as ink overflow, by capillary action. However, once the fiber mat has cleaned the nozzle face, it is difficult to remove dirt from the fiber mat. After many wiping operations, the fiber mat is filled with a lot of dirt and the nozzle face is no longer effectively cleaned. However, in the case of a printer with a short working life or a printer that allows the replacement of the wiper, the fiber mat provides the most efficient wiper. Combined wiper maintenance station It will be appreciated that some print head designs are most efficiently cleaned by the combination of the wipe configurations described above. For example, a single blade combines a series of skewed blades or a series of parallel blades with fiber mats therebetween. The combined wiper maintenance station can be derived by selecting a particular wiper structure based on individual strengths and strengths. Printhead Maintenance Facility Drive System Figures 47 through 50 show the media feed drive and printhead maintenance drive in more detail. Figure 4 8 shows the printhead maintenance carousel 150 and the drive system independently. The maintenance dial 1 5 显示 shown is presented to the print head (not shown) by the wiper blade 162. The perspective view shown in Fig. 48 reveals that the paper discharge guide 322 is guided to the discharge driving roller 178. On the other side of the wiper blade 162, the main drive roller shaft 186 is shown extending from the main drive roller pulley 330. This pulley is driven by a main drive roller belt 92 which engages the medium feed motor 190. The medium feed drive belt 182 synchronizes the rotation of the main drive roller 186 and the discharge roller 178. The exploded perspective view of Figure 49 shows the individual components in more detail. In particular -36- 200932565 This perspective map best illustrates the balanced turntable lift mechanism. The turntable lift drive shaft 160 extends between two identical turntable lift cams. One end of the turntable lift shaft 160 is keyed to the turntable lift spur gear 174. The spur gear 174 engages the worm gear 176 and the turntable lift motor 324 drives the worm gear 176. The turntable lift rotary sensor 3 3 4 provides feedback to a print engine controller (not shown) that can determine the displacement of the turntable from the print head by the angular displacement of the cam 1 72. The turntable lift cam 172 contacts the individual turntable lift arms 158 by camming rollers 168 (it is understood that the cam engaging rolls can be surfaces of low friction material, such as high density polyethylene (HDPE)). Since the cams 172 are identical and are also mounted to the turntable lift shaft 160, the displacement of the turntable lift arms 158 is also the same. Figure 47 is a cross-sectional view taken on line 7-7 of Figure 2A with the print head 匣 2 and the print head maintenance carousel 1 50 removed. This figure provides a clear view of the turntable spur gear 174, its adjacent lift cam 172, and the corresponding turntable lift arm 158. Because each lift arm 158 is equidistant from the midpoint of the turntable 150, the turntable lift drive is fully balanced and symmetrical when the turntable is raised and lowered. This is used to maintain the longitudinal direction of the various print head maintenance stations parallel to the print head integrated circuit. The best map solution for the rotary drive of the turntable is shown in the enlarged partial decomposition view of Fig. 50. A turntable rotary motor 326 is mounted to the side of the turntable lift configuration 170. Stepper motor sensor 3 28 provides feedback on the rate and rotation of motor 326 to the print engine controller (pEC).

Because the turntable rotation and turntable lift are separated by separate drives and each drive is powered by a stepper motor that provides an engine controller for motor speed and rotation, the maintenance procedure for the printer is optional. The turntable rotation motor 326 can be driven at any of two directions, so that the nozzle face can be wiped in both directions, and the wiper blade can be cleaned against the pad 152 in both directions. This can be particularly useful if the paper dust and its wiping to the nozzle face are mechanically opposite to the surface irregularities on the nozzle face, and such mechanically deformable wiper blades 62 and nozzle faces are often removed. It is useful to reduce the wiper scraping rate when making contact, and then increase the rate when the wiper leaves the nozzle face. The rate is true when the wiper blade and the nozzle face are initially in contact, and then the rate is increased when wiping. Similarly, the wiper blade 162 is moved through the blade 154 in a direction that is more than the rate at which the wiper blade moves past the cleaning pad 152 and wipes the blade 1 62 in any direction in any number of revolutions. Moreover, the order in which each maintenance station presents to the print head is programmed into the print engine controller' and/or left to the user. The invention is described herein by way of example only. General skill recognition does not deviate from the modifications of the spirit and scope of the broad invention. [Simple description of the diagram] Controlled to print a wide range of variable absorption of any absorbing dirt. In. When the 162 is wiped, the speed is also slowed down. It can be easily scraped in the wiper.
