[0041] [防止感光鼓和显影辊损坏的方法以及装置]  [Method and Apparatus for Preventing Damage of Photosensitive Drum and Developing Roller]
[0042] 图 5是本发明处理盒中显影辊和感光鼓之间安装隔离纸的示意图。  5 is a schematic view showing the installation of a release paper between a developing roller and a photosensitive drum in the process cartridge of the present invention.
[0043] 如上所述， 显影辊 11用于将显影剂输送至感光鼓 21上， 因此， 当处理盒完成组 装后， 显影辊 11必定处于与感光鼓 21相对的位置， 尤其在接触式显影方式中， 显影辊 11与感光鼓 21接触设置。 处理盒从出厂到终端用户使用往往会耗费较长 吋间， 在此过程中， 不仅显影辊 11的表面会变形， 感光鼓 21的表面也会被污染 ， 从而使得打印出现问题。  [0043] As described above, the developing roller 11 is for conveying the developer onto the photosensitive drum 21, and therefore, after the process cartridge is assembled, the developing roller 11 is necessarily at a position opposed to the photosensitive drum 21, particularly in the contact developing mode. The developing roller 11 is disposed in contact with the photosensitive drum 21. The process cartridge is often used for a long period of time from the factory to the end user. In the process, not only the surface of the developing roller 11 is deformed, but also the surface of the photosensitive drum 21 is contaminated, thereby causing problems in printing.
[0044] 本发明还提供一种防止显影辊 11和感光鼓 21损坏的方法， 采用如下步骤： The present invention also provides a method of preventing damage to the developing roller 11 and the photosensitive drum 21, using the following steps:
[0045] a.组装处理盒； [0045] a assembly process cartridge;
[0046] b.在显影辊 11和感光鼓 21之间安装隔离装置。  [0046] b. An isolating device is installed between the developing roller 11 and the photosensitive drum 21.
[0047] 如图 5所示， 所述隔离装置优选的是隔离纸 3， 当处理盒组装完毕后， 直接在显 影辊 11和感光鼓 21之间插入隔离纸 3， 使得显影辊 11和感光鼓 21不直接接触， 因 而， 可有效防止因显影辊 11和感光鼓 21长吋间接触造成的打印缺陷。  [0047] As shown in FIG. 5, the isolating device is preferably a release paper 3, and after the process cartridge is assembled, the release paper 3 is directly inserted between the developing roller 11 and the photosensitive drum 21, so that the developing roller 11 and the photosensitive drum 21 is not in direct contact, and therefore, printing defects caused by the long contact between the developing roller 11 and the photosensitive drum 21 can be effectively prevented.
[0048] 当然， 所述隔离装置并不限于隔离纸 3， 还可以是安装在处理盒两个纵向末端 的隔离销 （未示出） ， 当处理盒组装完毕后， 分别在处理盒的两个纵向末端安 装隔离销， 所述隔离销插入显影辊 11和感光鼓 21之间， 使得显影辊 11和感光鼓 2 1不直接接触， 也可以有效防止显影辊 11变形以及感光鼓 21表面被污染， 从而造 成打印缺陷。 [0048] Of course, the isolating device is not limited to the release paper 3, but may be a spacer pin (not shown) installed at two longitudinal ends of the process cartridge. When the process cartridge is assembled, respectively, two of the process cartridges are respectively The longitudinal end is provided with a spacer pin which is inserted between the developing roller 11 and the photosensitive drum 21 so that the developing roller 11 and the photosensitive drum 2 1 are not in direct contact, and the deformation of the developing roller 11 and the surface of the photosensitive drum 21 are effectively prevented from being contaminated. Make Become a print defect.
[0049] [减小粉仓中残余显影剂量的方法]  [Method of reducing the amount of residual developer in the powder silo]
[0050] 图 6是本发明处理盒中粉仓面向废粉仓的结构示意图； 图 7是本发明处理盒中粉 仓背向废粉仓的结构示意图。  6 is a schematic view showing the structure of the powder bin facing the waste toner bin in the process cartridge of the present invention; and FIG. 7 is a schematic view showing the structure of the powder silo facing away from the waste toner bin in the process cartridge of the present invention.
[0051] 如图 6和图 7所示， 粉仓 1的壳体包括面向废粉仓的前侧面 10a以及背向废粉仓的 后侧面 10b， 所述前侧面 10a上设置有第一检粉口 101， 后侧面 10b上设置有第二检 粉口 102， 所述第一检粉口 101与第二检粉口 102相对设置， 其工作原理是： 根据 穿过第一检粉口 101和第二检粉口 102的光线多少判断粉仓 1中显影剂的剩余量。 当粉仓 1中的显影剂较多吋， 第一检粉口 101和第二检粉口 102之间的光路完全被 显影剂阻断， 此吋， 打印机显示处理盒中的显影剂量充足； 当粉仓 1中的显影剂 逐渐被消耗掉， 第一检粉口 101和第二检粉口 102之间的光路不能再完全被显影 剂阻断， 而是有光线穿过第一检粉口 101和第二检粉口 102吋， 打印机根据透过 的光线量显示显影剂的剩余量。  [0051] As shown in FIG. 6 and FIG. 7, the housing of the powder silo 1 includes a front side 10a facing the waste toner box and a rear side 10b facing away from the waste toner box, and the front side surface 10a is provided with a first powder test. a second powder detecting port 102 is disposed on the rear side surface 10b, and the first powder detecting port 101 is disposed opposite to the second powder detecting port 102, and the working principle thereof is: according to passing through the first powder detecting port 101 and The light of the second powder detecting port 102 determines the remaining amount of the developer in the powder bin 1. When the developer in the powder silo 1 is more enthalpy, the optical path between the first powder detecting port 101 and the second powder detecting port 102 is completely blocked by the developer. Thereafter, the printer displays that the amount of the developer in the process cartridge is sufficient; The developer in the powder silo 1 is gradually consumed, and the optical path between the first powder detecting port 101 and the second powder detecting port 102 can no longer be completely blocked by the developer, but light passes through the first powder detecting port 101. And the second powder detecting port 102, the printer displays the remaining amount of the developer based on the amount of light transmitted.
[0052] 然而， 由于所述第一检粉口 101和第二检粉口 102均不是设置在粉仓 1的最底部 ， 因此， 当打印机显示处理盒中的显影剂被消耗完吋， 实际上， 位于所述检粉 口与粉仓 1的最底部之间还残留有显影剂， 也就说粉仓 1中的显影剂并没有被完 全消耗掉， 如果终端用户按照打印机的提示而更换处理盒， 势必会造成显影剂 的浪费。  [0052] However, since neither the first powder detecting port 101 nor the second powder detecting port 102 is disposed at the bottom of the powder bin 1, when the printer displays that the developer in the process cartridge is consumed, actually There is still a developer remaining between the powder detecting port and the bottom of the powder bin 1, that is, the developer in the powder bin 1 is not completely consumed, if the end user replaces the process cartridge according to the prompt of the printer. , will inevitably cause waste of developer.
[0053] 本发明还提供一种减小粉仓中残余显影剂量的方法， 具体为遮挡至少第一检粉 口 101和第二检粉口 102之一， 使得光线不能同吋穿过第一检粉口 101和第二检粉 Π 102。  [0053] The present invention also provides a method for reducing the amount of residual developer in the powder silo, specifically shielding at least one of the first powder detecting port 101 and the second powder detecting port 102, so that the light cannot pass through the first inspection. Powder mouth 101 and second powder tester 102.
[0054] 所述遮挡至少第一检粉口 101和第二检粉口 102之一的方式可以采用黑色颜料涂 覆至少第一检粉口 101和第二检粉口 102之一， 也可以采用在至少第一检粉口 101 和第二检粉口 102上安装不透光部件的方式。  [0054] The manner of shielding at least one of the first powder detecting port 101 and the second powder detecting port 102 may be performed by coating at least one of the first powder detecting port 101 and the second powder detecting port 102 with a black pigment, or may be adopted. A manner of mounting the opaque member on at least the first powder inspection port 101 and the second powder inspection port 102.
[0055] 如上所述， 本发明将另一个尺寸的送粉辊再生， 使得再生后的送粉辊能够用于 目标处理盒的再生， 从而达到节约资源的目的。  As described above, the present invention regenerates the powder feeding roller of another size so that the regenerated powder feeding roller can be used for the regeneration of the target process cartridge, thereby achieving the purpose of resource saving.
