Description

  The present invention relates to an image forming apparatus such as a copying machine, a printer, and a facsimile, and relates to measures against misprints that occur during image formation.

  When a user prints a document with a copying machine, the user sets the document on a platen glass or ADF (Auto Document Feeder), and presses a start button to execute printing. In particular, when the number of originals is large, a user can set a large number of originals without setting the originals one by one on the platen glass by automatically acquiring image data of a plurality of originals by setting the originals on the ADF. Can print automatically.

  Further, as described above, not only the image data of the original is directly acquired from the copying machine, but also the printing data is received from a personal computer connected to the copying machine, another copying machine, a facsimile, etc., and the printing data is rasterized. Printing is performed based on the processed image data.

  As described above, in recent years, many image forming apparatuses that can automatically perform a series of operations from acquisition of image data of a document to printing while taking into consideration a network environment have been provided.

  However, since the image data of the document is automatically acquired and printed as described above, if there is a typographical error in a part or the whole of the document, or if there is an error in the document arrangement order, the document is further inclined on the platen glass. If the start button is pressed once and a print execution instruction is issued, a printed matter that is different from the user's request, that is, a so-called printing failure occurs.

  In such a case, since a part of or a whole printed matter includes a page where a printing failure has occurred (hereinafter referred to as a printing failure page), the user reprints with a correct document after printing and prints from the printed matter. It is necessary to remove the defective page and replace it with a reprinted one.

  In addition, when the user confirms the printed matter discharged to the discharge tray during printing and notices that there is a defective print page, the user can forcibly stop printing by pressing a stop button or the like. As in the case described above, the printed matter contains a print defect page.

  For this reason, in Patent Document 1, the image forming apparatus determines whether or not the page is a defective print by comparing the image data of the document with the image data of the printed matter that is the output result, and a defective print page is generated. In such a case, measures are taken to prevent mixing of defective print pages into the printed matter by separating and discharging the corresponding paper.

  In Patent Document 2, when it is determined that there is a certain difference between the image data of the document and the image data of the printed matter that is the output result, the image data of the document and the image data of the printed matter that is the output result are displayed side by side, By selecting the paper discharge port after the visual confirmation by the user, the printing failure page is prevented from being mixed into the printed matter.

JP 2000-10443 A JP 2009-65480 A

  However, in Patent Documents 1 and 2, a sensor for reading the image data of the printed matter output based on the original is required, so that the manufacturing cost is greatly increased. Furthermore, since it is necessary to compare the image data with the image data of the printed matter that is the output result, the printing speed is reduced due to a significant increase in the image processing time. This is extremely fatal especially in fields such as recent production printing that require high-speed printing.

  Further, in Patent Documents 1 and 2, the acquired original document may be misplaced in a part or the whole of the original document, when there is an error in the document arrangement order, or when the original document is set obliquely on the platen glass. Since there is an error in the image data itself, defective print pages are inevitably mixed in the printed matter. In such a case, the user needs to reprint the defective print page and replace the defective print page with the reprinted printed matter.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus capable of easily outputting a correct printed material when a printed defective page is mixed with the printed material. is there.

  The CPU 21 comprehensively controls each unit of the image forming apparatus main body 10. In addition, the CPU 21 expands a program designated from various programs stored in the ROM 22 in the RAM 23 and executes various processes in cooperation with the program expanded in the RAM 23. That is, in the embodiment of the present invention, the CPU 21 corresponds to the “control unit” in the present invention.

  The ROM 22 stores various programs and various data as described above. For example, a program for realizing a page replacement function and various screen data displayed on the touch panel 161 are stored.

  The RAM 23 temporarily stores program data as a work area. For example, the RAM 23 can serve as a page memory that stores printing data stored in the HDD 24 for printing by the printer unit 13 as decompressed data for one page.

  The HDD 24 stores print data and print setting data input from the operation unit 16. In the embodiment of the present invention, the print data is stored in the HDD 24, but an image memory for storing only the print data may be provided instead of the HDD 24.

  The image processing unit 25 processes the print data based on the print setting data so that the printer unit 13 forms an image on a sheet. Specifically, the print data is processed based on gradation correction and density and magnification designated by print setting data. When the page replacement function is included in the print setting data, image processing is executed only for the print data acquired again from the original of the defective print page to be replaced set by the function.

  The connection unit 26 is a communication interface that performs parallel communication or serial communication via the communication lines L1 and L2. As a result, the image forming apparatus main body 10 can be connected to the post-processing apparatus 30 and the large-capacity paper feeding apparatus 40. The communication means may be not only wired communication using a connection line but also wireless communication such as infrared communication.

  The printer controller unit 27 includes various interfaces such as a NIC (Network Interface Card), a MODEM (Modulator-DEModulator), and a USB (Universal Serial Bus), and connects to an external device via a communication line L3. For example, the printer controller unit 27 is connected to a personal computer 50 that is an external device, and receives print data from the personal computer 50. Note that there may be a plurality of external devices to be connected, and the external device may be a multifunction device or a printer other than the personal computer 50.

  Further, when the print data transmitted from the personal computer 50 is made up of PDL (Page Description Language) which is a page description language, the printer controller unit 27 prints the print data in the bitmap format rasterized by the image processing unit 25. Converted to data.

  The communication unit 28 receives print data from the printer controller unit 27. The received print data is stored in the HDD 24 as described above.

  FIG. 3 shows an operation flow of the image forming apparatus 1 in the embodiment of the present invention. This operation flow is executed by the CPU 21.

  The CPU 21 displays the print setting screen 60 on the touch panel 161 (S101). An example of the print setting screen 60 displayed at this time is shown in FIG.

  For example, the user can instruct the CPU 21 to perform a conventional process, a page replacement function setting process, or a print process via the print setting screen 60.

  The CPU 21 determines which of these processes has been selected by the user (S102).

  When the CPU 21 determines that the user has selected the conventional process (S102 conventional process), the CPU 21 executes the conventional process (S103).

  The conventional processing here refers to processing other than page replacement function setting processing and printing processing. In the embodiment of the present invention, for example, the conventional processing indicates setting processing related to printing other than the page replacement function setting processing, and processing related to fax, scan, box, and the like.

  When the CPU 21 determines that the user has selected the page replacement function setting process (S102 page replacement), the CPU 21 executes the page replacement function setting process (S104). Specifically, the CPU 21 depresses the application setting 61 area in the print setting screen 60 shown in FIG. 4A by the user, and subsequently displays the application setting screen 70 shown in FIG. 4B. It is determined whether the area of the page replacement function 71 is pressed.

  Here, the page replacement function setting process is a process in which the user sets a specific operation of the page replacement function. In addition, the page replacement function is to reprint only the defective print page from the printed material and reprint it as the defective print page in the printed material when the printed material contains the defective printed page. This is a function for executing an operation of replacing the printed material. A specific operation flow of the page replacement function setting process will be described later.

  In the embodiment of the present invention, a program for realizing the page replacement function is stored in the ROM 22. Further, the page replacement function is executed by the CPU 21.

  When the CPU 21 determines that the user has selected the printing process (S102 printing process), the CPU 21 executes the printing process (S105).

  Here, the printing process indicates a printing process using the above-described page replacement function or a normal printing process as usual. A specific operation flow of the printing process will be described later.

  FIG. 5 shows an operation flow of the page replacement function setting process in the embodiment of the present invention.

  The CPU 21 displays the page replacement function setting screen 80 on the touch panel 161 (S201). An example of the page replacement function setting screen 80 displayed at this time is shown in FIG.

  The page replacement function setting screen 80 includes an instruction area 81 for displaying an operation instruction to the user, a replacement page setting area 82 for the user to set a page to be replaced, and a printed matter that has been output in which printing failure pages are mixed.

  Below, detailed description of each area | region is described.

  The instruction area 81 is an area for displaying an operation instruction to the user. For example, the instruction area 81 displays information “Please select replacement page, output paper tray, and reprint paper tray.” Further, the information displayed in the instruction area 81 is not limited to this, and may be an explanation of various setting areas such as the replacement page setting area 82, for example.

  The replacement page setting area 82 is an area for setting a defective print page. That is, the replacement page setting area 82 corresponds to the “printing defective page setting portion” of the present invention.

  In the embodiment of the present invention, it is assumed that a printing failure page is generated on the fifth page of the printed material printed on one side in a 10-page document printed on both sides. It is assumed that a defective print page is generated when a document is accidentally fed obliquely when a document is fed from the ADF paper feed tray 111. FIG. 10 shows an example of a part of a printed matter that has already been printed and contains a print defect page. FIG. 10 is an external view of a first page 1001 of a printed material that is a defective print page, a second page 1002 of the printed material, a fifth page 1005 of the printed material, and a 10th page 1010 of the printed material.

  In this case, the user can designate a defective print page by depressing each page designation button 87 in the replacement page setting area 82 and depressing the numeric key “5” of the operation unit 16.

  In the embodiment of the present invention, 18 page designation buttons 87 are prepared, but further settings can be performed by pressing the next item button 88 or the previous item button 89. The number of page designation buttons 87 is not limited to this.

  Further, the form of the page designation button 87 is not limited to this. For example, a page designation button that can designate continuous pages may be used. In this case, for example, a defective print page can be designated as “P.5 to P.8”. As a result, a large number of defective print pages can be designated with a single setting, which improves the convenience for the user.

  As described above, the output paper tray area 83 is an area for setting a paper tray for storing output printed matter in which defective print pages are mixed. That is, the output paper tray area 83 corresponds to the “storage setting unit” of the present invention. For example, when an output printed matter in which printed defective pages are mixed is discharged to the paper discharge tray 31, the user takes out the printed material from the paper discharge tray 31 and is a paper tray set by the user, that is, an embodiment of the present invention. Is stored in the paper tray 143.

  It should be noted that the printed matter that has been output and contains defective printing pages may be stored in any of the other paper trays 141, 142, and 144 of the paper feeding unit 14 and the paper tray of the large-capacity paper feeding device 40.

  The reprinting paper tray area 84 is an area for setting a paper tray in which paper used for reprinting is stored by the user when reprinting a defective print page. That is, the reprint paper tray area 84 corresponds to the “storage setting unit” of the present invention.

  In the embodiment of the present invention, the paper tray 141 of the paper feeding unit 14 is set. Although not shown, the paper used for reprinting may be stored in any of the other paper trays 142, 143, 144 of the paper feeding unit 14 and the paper tray of the large capacity paper feeding device 40.

  The user sets the replacement page setting area 82, the output paper tray area 83, and the reprinted paper tray area 84 with reference to the instruction area 81 on the page replacement function setting screen 80 (S202). When the CPU 21 determines that each area has been set by the user (S202 setting), the CPU 21 sets the input setting value as print setting data for reprinting (S203).

  When the user ends without setting the page replacement function, the user presses the cancel button 85 (S202 cancel). In the embodiment of the present invention, when the cancel button 85 is pressed, the screen displayed on the touch panel 161 is switched from the page replacement function setting screen 80 to the print setting screen 60.

  When completing the setting, the user presses an OK button (S202 OK).

  When the CPU 21 determines that the OK button 86 has been pressed, the CPU 21 turns on the page replacement function setting of the print setting data, stores the reprint print setting data in the HDD 24 (S204), and confirms the replacement target job selection on the touch panel 161. The screen 90 is displayed in POPUP (S205). An example of the replacement target JOB selection confirmation screen 90 displayed at this time is shown in FIG.

  The replacement target JOB selection confirmation screen 90 is a screen for allowing the user to select whether or not to use print setting data stored in the HDD 24 as print setting data when reprinting a defective print page. is there. Thereby, for example, it is possible to easily reset the print setting data of a printed matter in which defective print pages stored in the HDD 24 are mixed.

  The user sets whether or not to use the print setting data stored in the HDD 24 with reference to the instruction area 91 on the replacement target JOB selection confirmation screen 90 (S206).

  When the CPU 21 determines that the No button 92 has been pressed (No at S206), the page replacement function setting process is terminated.

  On the other hand, when the CPU 21 determines that the YES button 93 has been pressed (YES in S206), the CPU 21 displays the replacement target JOB selection screen 100 on the touch panel 161 (S207). An example of the replacement target JOB selection screen 100 displayed at this time is shown in FIG.

  Here, the replacement target JOB selection screen 100 is a screen for allowing the user to select print setting data stored in the HDD 24 as print setting data when reprinting a defective print page. Note that the print setting data of the latest print process used immediately before is preferably displayed with priority. That is, in the embodiment of the present invention, the replacement target JOB selection screen 100 corresponds to the “reprint setting unit” of the present invention, and the touch panel 161 that displays the screen corresponds to the “display unit” of the present invention.

  The replacement target JOB selection screen 100 includes an instruction area 101 for displaying an operation instruction to the user, a plurality of job designation buttons 102 for displaying print setting data stored in the HDD 24 one by one, a next item button 103, a previous item button 104, and a cancel. A button 105 and a confirm button 106 are provided.

  The user designates print setting data for reprinting a defective print page by selecting the job designation button 102 from the displayed job list with reference to the instruction area 101 of the replacement target job selection screen 100. (S208). When the CPU 21 determines that the job has been designated by the user (S208 job designation), the CPU 21 sets the designated job as print setting data for reprinting (S209).

  However, when a print failure page occurs in a printed material created by stapling or folding processing, the page cannot be replaced by reprinting because the appearance of the printed material is arranged. For this reason, in the embodiment of the present invention, it is assumed that JOBs in which stapling processing and folding processing are included in the print setting data are not displayed on the replacement target JOB selection screen 100.

  When the user ends without setting print setting data for reprinting a defective print page, the user presses the cancel button 105 (S208 cancel). In the embodiment of the present invention, when the cancel button 105 is pressed, the screen displayed on the touch panel 161 is switched from the replacement target JOB selection screen 100 to the print setting screen 60.

  When completing the setting, the user presses the confirmation button 106 (S208 confirmation).

  If the CPU 21 determines that the confirm button 106 has been pressed, it reflects the JOB stamp setting print data set in S209 in the reprint print setting data (S210), and replaces the screen displayed on the touch panel 161. Switch from the JOB selection screen 100 to the print setting screen 60.

  In the embodiment of the present invention, eight JOB designation buttons 102 are displayed on one screen in the JOB list of the replacement target JOB selection screen 100. However, when the next item button 102 or the previous item button 103 is pressed, The above print setting data can be displayed. Further, the number of JOB designation buttons 102 is not limited to this.

  Next, the printing process will be described with reference to FIG. The printing process is controlled by the CPU 21. In the reprinting, it is assumed that an output printed matter in which defective printing pages are mixed is stored in the paper tray 143 in advance. Further, it is assumed that the printed material is punched by a punching machine that is the post-processing device 30.

  When a start button (not shown) is pressed, the CPU 21 refers to reprint print setting data stored in the HDD 24 and determines whether the page replacement function is valid (S301).

  When the CPU 21 determines that the page replacement function is not valid (S301 OFF), the CPU 21 performs a normal printing process (S302) and ends the process.

  On the other hand, when the CPU 21 determines that the page replacement function is valid (S301 ON), the CPU 21 reads the original of the defective print page to be replaced set on the platen glass 122 or the automatic document feeder 11 by the user (S303). ). In the embodiment of the present invention, it is assumed that one document of the fifth page is set in the automatic document feeder 11 at the time of reprinting.

  The CPU 21 confirms the number of read originals and determines whether or not the number of originals coincides with the number of defective printing pages set in the replacement page setting area 82 (S304).

  If the CPU 21 determines that there is a mismatch (S304 does not match), the touch panel 161 displays a message “The number of originals does not match the number of replacement pages. Check the originals and reread them” (S305). The displayed message is not limited to this. Further, a warning sound may be used instead of the message display, and these may be combined.

  When the start button is pressed again after displaying the message (S306), the CPU 21 determines that the user has set the original again, and reads the original of the defective print page again (S303). If the start button has not been pressed, although not shown, the CPU 21 suspends the printing process and displays the print setting screen 60 or the application setting screen 70 on the touch panel 161.

  In S304, when the CPU 21 determines that they match (S304 matches), it sets 1 to the counter X and performs initialization (S307). Here, the counter X is for counting the pages of printed matter stored in the paper tray 143 of the paper feeding unit 14 at the time of reprinting. The counter X is stored in the RAM 23.

  Subsequently, the CPU 21 determines whether the Xth page of the printed material is a defective print page (S308). For example, in the embodiment of the present invention, a defective print page is generated on the fifth page of a 10-page document that is printed on both sides. Therefore, it is determined that the first page of the printed material printed on one side is not a defective print page.

  When the CPU 21 determines that the page is not a defective printing page (NO in S308), the printed matter stored in the paper tray 143 is discharged to the discharge tray 31 as it is (S309). At this time, since the printed material has already been punched, the CPU 21 does not perform the punching process on the printed material. In other words, since the punching process is not performed on the printed material that has already been punched, it is possible to avoid the situation where the punching is performed again at a position slightly deviated from the first punching position, and unnecessary punching processing is performed. It can be omitted.

  On the other hand, if the CPU 21 determines that the page is a defective print page (S308: YES), it executes reprinting (S310). For example, in the embodiment of the present invention, the fifth page of the printed material printed on one side is determined to be a defective print page, and the CPU 21 executes reprinting. Specifically, the CPU 21 forms an image based on the printing data of the original read again by the scanner unit 12 on the paper in the paper tray 141, forms the image after punching it, and uses this as a printed matter as the paper discharge tray 31. Eject the paper.

  The defective print page stored in the paper tray 143 is discharged to a discharge tray 32 different from the discharge tray 31 (S311). That is, the paper discharge tray 32 corresponds to a “printing defective page paper discharge unit” of the present invention. The defective print page may be discharged to the discharge tray 33.

  In the embodiment of the present invention, at the time of reprinting, the paper discharge tray 31 is used for discharging printed matter other than the defective print page and the reprinted printed matter, and the paper discharge tray 32 discharges the defective print page. Used to make paper. That is, the printed matter that does not include the printing failure page and the printing failure page is discharged to separate discharge trays. This eliminates the need for the user to replace the defective print page in the printed material with the reprinted printed material.

  The CPU 21 determines whether or not the counter X is the last page of the printed material (S312).

  If the CPU 21 determines that it is not the last page (NO in S312), it adds 1 to the counter X (S313) and returns to S308.

  On the other hand, if the CPU 21 determines that it is the last page (YES in S312), it determines whether or not reprinting for the required number of copies has been completed (not shown), and if it is completed, the printing process is terminated.

  The embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiments, and changes and additions within the scope of the present invention may be made. It is included in the present invention.

  For example, in the embodiment of the present invention, the output form as a printed matter is single-sided printing, but the present invention is not limited to this, and the output form as a printed matter is double-sided printing or Nin1 printing for outputting a plurality of originals as one page of the printed matter. It is good. And CPU21 performs a printing process in consideration of these.

  With reference to FIG. 11, a case will be described where a printing failure page is generated on the first page of a printed material in which a 10-page original is printed on both sides in 2in1. FIG. 11 shows the first page 1101 of the printed matter that is a defective print page, the second page 1102 of the printed matter, the third page 1103 of the printed matter, the fourth page 1104 of the printed matter, the fifth page 1105 of the printed matter, and the six pages of the printed matter. An external view of the eye 1106 is shown.

  In this case, as shown in FIG. 11, on the first sheet of the printed matter on which the printing failure page has occurred, the first and second pages of the document are printed on the front surface, and the third and fourth pages of the document are printed on the back surface. Therefore, the user needs to set the first to fourth pages of the document on the automatic document feeder 11 at the time of reprinting. Then, the CPU 21 executes the printing process by determining from the print setting data that the output form of the printed matter is 2 in 1 and duplex printing, so that the defective printing page corresponds to four pages of originals.

  Further, in the embodiment of the present invention, description has been made using a document that has been printed on both sides as a document, but the present invention is not limited to this, and the document may be printed on one side.

  In the embodiment of the present invention, only the original of the defective print page to be replaced is set in the automatic document feeder 11 at the time of reprinting. However, the present invention is not limited to this. It is also possible to set all the originals to be included in the automatic original feeder 11 and acquire only the printing data for the original of the defective print page to be replaced.

  In the embodiment of the present invention, the print data of the defective print page to be replaced is acquired from the automatic document feeder 11. However, the present invention is not limited to this. It may be converted based on print data received from the device.

  Further, in the embodiment of the present invention, an example is given in which a job whose stapling process or folding process is included in the print setting data is not displayed on the replacement target job selection screen 100, but these are displayed in a format that cannot be selected. For example, the JOB designation button 102 may be shaded.

  In the embodiment of the present invention, “JOBNo” indicating a job number and “copy No.”, “copy”, “fax”, “scan”, “box”, etc. are displayed as the print setting data items displayed on the job designation button 102 of the replacement target job selection screen 100. “Processing mode” indicating the processing of the document, “Number of pages”, “Number of copies”, and “Output form” indicating single-sided / double-sided printing are displayed. “Post processing” indicating “printing form” indicating Nin1 printing, “date and time” indicating printing date and time, “user name” indicating the user who executed the job, “JOB name” indicating the job executed, etc. Various information may be displayed.

  Further, in the embodiment of the present invention, the replacement target JOB selection confirmation screen 90 is displayed in POPUP. However, the present invention is not limited to this, and may be displayed on the touch panel 161 as a normal screen that is not POPUP display.

  In the embodiment of the present invention, the image forming apparatus main body 10 is provided with one paper discharge port 15, but a paper discharge tray that includes two or more paper discharge ports and is connected to the paper discharge ports. The printed matter may be loaded on the printer. As a result, the reprinted printed matter and the defective print page can be discharged to different discharge outlets without using the post-processing device 30. In this case, the paper discharge tray connected to one of the two paper discharge openings corresponds to the “print defective page discharge portion” of the present invention.

  Further, the paper stored in the paper trays 141 to 144 and the paper tray of the large capacity paper feeding device 40 is not limited to the embodiment of the present invention. For example, various papers such as B4 and B5 paper sizes, thick paper or thin paper, and colored paper may be used.

  Further, the print setting data or the print data may be stored in various storage media such as a hard disk, an EEPROM (Electronically Erasable and Programmable Read Only Memory), and a USB (Universal Serial Bus) memory as necessary.

  The means and method for performing various processes in the image forming apparatus 1 according to the embodiment of the present invention can be realized by either a dedicated hardware circuit or a programmed computer. The program may be provided by a computer-readable recording medium such as a flexible disk or a CD-ROM, or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is usually transferred to and stored in a storage unit such as a hard disk. The program may be provided as a single application software, or may be incorporated into the software of the device as one function of the device.
