Description

  The present invention relates to an image forming apparatus.

  When a user intends to print using an MFP (Multifunctional Printer) including a paper feed unit, the user issues a print instruction after setting paper in the paper feed unit. Then, the MFP instructed to print prints on the paper conveyed from the paper feeding unit.

  Here, in a printing apparatus such as a printer equipped with a paper feeding unit, a technique for avoiding a trouble that causes a paper feeding failure or a conveyance failure by detecting a user's paper setting error and issuing a warning is disclosed. This is disclosed in Japanese Patent No. 55710 (Patent Document 1).

  According to the technique disclosed in Patent Document 1, if the time from when the paper feed roller is started until the paper feed sensor provided on the paper transport path detects the paper is within a predetermined time, the paper is fed. It is determined that the paper loaded in the section is not correctly stacked and that the paper is skewed on the conveyance path, and a warning is issued to the user to correctly stack the paper.

  In addition, when printing data is sent to the printing device, printing results that are not intended by the user due to a mismatch between the size of the paper loaded in the printing device and the size of the paper in the sent printing data. A technique for avoiding this is disclosed in Japanese Patent Laid-Open No. 2007-34957 (Patent Document 2).

  According to the technology disclosed in Patent Document 2, in a printing apparatus having a function of detecting the paper width, the size width of the loaded paper is compared with the paper size width stored in the print job data. Is done. If both size widths are different, the size width of the loaded paper is compared with the size length of the paper stored in the print job data. In response to the user's request, the image data in the print job data is rotated by 90 ° and printed.

  Also, in printers that do not have a dedicated paper size detection mechanism in the cassette, if the user makes a mistake in entering the paper size, a message will be displayed on the operation panel and an error will occur to the user. Is disclosed in Japanese Patent Application Laid-Open No. 9-240086 (Patent Document 3).

  According to the technique disclosed in Patent Document 3, when paper size information is input from the operation panel, the printer stores the input paper size information in the size memory. Then, the passage time at a predetermined position on the paper conveyance path is measured, and it is determined whether or not the measurement value of the passage time is within a range based on an upper limit value and a lower limit value preset for each paper size. . As a result, when it does not fall within the range, a warning that the paper size is abnormal is issued to the user.

  Next, a process flow of the digital multi-function peripheral 11 when the direction of the paper 50 set in the paper feed cassette 40 is erroneously input in printing a plurality of papers 50 will be described. FIG. 5 is a flowchart showing a processing flow of the digital multi-function peripheral 11 when printing a plurality of sheets 50. In the present embodiment, although the paper 50 is set in the A4 direction, that is, the vertical direction in the paper feed cassette 40, the display screen 21 inputs that the paper 50 is in the A4R direction, that is, the horizontal direction. The case will be described.

  First, the paper 50 is set in the paper feed cassette 40 (in FIG. 5, step S11, hereinafter “step” is omitted). Specifically, with reference to FIG. 3 and FIG. 4, the paper 50 is set in the vertical direction by the user. The control unit 12 detects that the paper 50 is set by detecting that the paper feed cassette 40 is closed.

  Next, the operation unit 13 receives the input of the setting direction of the paper 50 set in the paper feed cassette 40 along with the input of the number of copies to be printed (S12). Specifically, after the document is placed on a platen (not shown) by the user in the A4 direction, that is, in the vertical direction, the copy mode or the numeric keypad 31 or the like is used by using the touch panel function of the display screen 21 of the operation unit 13 or the like. The number of copies to be printed is input, and the direction of the paper 50 is input as “A4R”. FIG. 6 is a diagram illustrating an example of the display screen 21 that receives input in the setting direction of the paper 50. Referring to FIG. 6, in S <b> 12, on display screen 21 having a touch panel function, message 71 for prompting the user to input “Please input the paper setting direction”, “A4” selection key 72, A selection key 73 of “A4R” is displayed. In the present embodiment, the user presses the “A4R” selection key 72.

  Next, when the control unit 12 detects that the user presses the copy start key 32 (S13), the control unit 12 conveys the first sheet 50 from the sheet feeding cassette 40 to the image forming unit 15 (S14). Then, image formation is performed on the first sheet 50 (S15).

  FIG. 7 is a diagram illustrating an example in which an image is formed on the first sheet 50. Although the paper 50 is set in the paper feed cassette 40 in the vertical direction, an example of a printing error is shown because the paper 50 is input in the horizontal direction from the display screen 21. Referring to FIG. 7, an area 53 of an image formed when the paper 50 is set as A4R is indicated by a dotted line. A hatched area 51 indicates a portion where no image is formed on the paper 50. The user can notice an input error in the setting direction of the paper 50 from the image formed on the first paper 50.

  Thereafter, the digital multifunction peripheral 11 interrupts the conveyance of the second and subsequent sheets 50 (S16). Next, a screen prompting confirmation of the setting direction of the paper 50 is displayed (S17). FIG. 8 is a diagram illustrating an example of the display screen 21 that prompts confirmation of the setting direction of the paper 50. Referring to FIG. 8, in S <b> 17, a confirmation message 81 of “Please confirm the paper direction. Do you want to change the paper direction?” Is displayed on the display screen 21 having the touch panel function, and “Yes”. A selection key 82 and a “NO” selection key 83 are displayed.

  The user who confirms the area shown in FIG. 7 and notices that the paper 50 is set in the wrong direction in S12 presses the “Yes” selection key 82 (YES in S18). Thereafter, the display screen 21 that accepts the input in the paper setting direction displayed in S12 is displayed again (S20). Then, the user re-inputs the paper setting direction. In this case, of course, the user presses the “A4” selection key 73 shown in FIG. When the pressing of the selection key 73 is detected and the pressing of the copy start key 32 is detected again, the digital multi-function peripheral 11 resumes the conveyance of the second and subsequent sheets 50 and the image formation, and ends the processing. (S19).

  If the user does not need to change the setting direction of the sheet 50 after confirming the result of the first sheet on which image formation has been performed, the user presses the “No” selection key 83 (NO in S18). . Next, the digital multi-function peripheral 11 resumes conveyance of the second and subsequent sheets 50 and image formation (S19). Thereafter, the process ends.

  According to such a digital multi-function peripheral 11, the direction in which the paper 50 is set is input by the operation unit 13. Next, after the first image is formed, the control unit 12 interrupts the conveyance of the second and subsequent sheets 50, and sets the direction of the sheet set in the sheet setting unit and the sheet input in the input unit. Control is performed to display on the display screen 21 a screen that prompts the user to input a confirmation result as to whether or not the directions match. For this reason, the user can obtain an opportunity to confirm whether or not the paper setting direction is correctly input to the input unit. Therefore, when the setting direction of the paper 50 is erroneously input, it is possible to avoid a printing mistake for the second and subsequent sheets.

  Next, another embodiment of the present invention will be described. In the present embodiment, a processing flow of the digital multi-function peripheral 11 when the direction of the paper 50 set in the paper feed cassette 40 is erroneously input in printing one sheet will be described. FIG. 9 is a flowchart showing a processing flow of the digital multi-function peripheral 11 when printing one sheet of paper 50. Also in the present embodiment, even though the paper 50 is set in the A4 direction, that is, the vertical direction in the paper feed cassette 40, the display screen 21 inputs that the paper 50 is in the A4R direction, that is, the horizontal direction. The case will be described.

  First, the paper 50 is set in the paper feed cassette 40 (in FIG. 9, step T11, hereinafter “step” is omitted). Next, the operation unit 13 receives the input of the direction of the paper 50 set in the paper feed cassette 40 together with the input of the number of copies to be printed (T12). Referring to FIG. 6, also in the present embodiment, “A4R” selection key 72 is pressed by the user.

  Next, a confirmation screen for the set direction of the input paper 50 is displayed (T13). FIG. 10 is a diagram illustrating an example of the display screen 21 that receives an input in the setting direction of the paper 50 confirmed by the user. Referring to FIG. 10, on the display screen 21, a message 92 prompting the user to confirm the input direction of the paper 50 confirmed by the user “please check and input the direction of the paper to be set” and “A4R”. A selection key 93 and a selection key 94 “A4” are displayed. In FIG. 10, at T12, the user first pressed the “A4R” selection key 72 as the paper 50 setting direction, but after confirming the paper 50 setting direction, the “A4” selection key 94 was pressed. An example is shown.

  Next, when the control unit 12 detects that the user presses the copy start key 32 (T14), the control unit 12 conveys the first sheet 50 from the sheet feeding cassette 40 to the image forming unit 15 (T15). Then, image formation is performed on the first sheet 50 (T16), and the process is terminated.

  As described above, in the present embodiment, a confirmation screen for setting the paper 50 is displayed before image formation. For this reason, the user can have an opportunity to confirm whether or not the direction in which the paper 50 is set is correctly input before image formation is performed on the paper.

  In addition, when an input error is made contrary to the above-described embodiment, specifically, the paper 50 is set in the A4R direction, that is, in the horizontal direction in the paper feeding cassette 40. It is also possible to avoid a conveyance failure that may occur when A is input in the A4 direction, that is, the vertical direction. Here, the conveyance failure refers to a paper jam phenomenon based on a stay in the sheet conveyance path 54 where the leading end of the sheet 50 is detected at a predetermined position of the sheet conveyance path 54 and the trailing end is not detected.

  Here, a conveyance failure that occurs when the paper 50 is input in the vertical direction even though the paper 50 is set in the horizontal direction will be described. The detection time of the conveyance failure of the paper 50 set in the vertical direction is set shorter than the passing time of the paper 50 set in the horizontal direction. Accordingly, since the paper 50 is set in the horizontal direction, the trailing edge of the paper 50 is not detected even when the detection time for the conveyance failure of the paper 50 set in the vertical direction is reached. Then, the control unit 12 determines that the conveyance is defective. When the control unit 12 determines that the conveyance is defective, the operation of the digital multi-function peripheral 11 is interrupted, and the sheet 50 remains on the sheet conveyance path 54. That is, when an input mistake in the setting direction of the paper 50 is made, it takes time to remove the paper 50 from the time of forming the first image. However, according to the configuration described above, it is not necessary to remove the paper remaining on the paper transport path 54, and the burden on the user can be reduced.

As described above, according to the image forming apparatus according to the present invention, the user can obtain an opportunity to confirm whether or not the paper setting direction is correctly input to the input unit. In this case, it is possible to avoid a printing error due to an erroneous input of the paper 50 setting direction. Therefore, it is possible to reduce the possibility of printing errors.
