It goes without saying that the function of the jam backup process is a very convenient function for the user using the printing apparatus. Also recently,
There are many printing apparatuses having a double-sided printing mechanism for performing double-sided printing, and printing apparatuses having a punching mechanism for making a punched hole in printed paper.

[0005] Normally, if the jammed paper is removed, the printing process is continued by the jam backup process. However, even if the jammed paper is removed, the cause of the paper jam in the double-sided printing mechanism may not be completely eliminated because it is in a place different from what the user thinks. For example, there is a case where a paper jam always or frequently occurs in the duplex printing mechanism due to a mechanical failure. In this case, if the function of the jam backup process is started, the paper is jammed again by the duplex printing mechanism because the duplex printing is still performed.

Further, there is a case where a paper jam always or frequently occurs due to a mechanical failure due to a punch mechanism. In this case, if the function of the jam backup process is started, the sheet is jammed again by the punch mechanism because the punch execution mode is maintained.

When a large-capacity readable / writable storage device such as a hard disk is mounted on the printing apparatus, these large-capacity readable / writable storage devices can also be used.

Conventionally, when a paper jam occurs during printing, the printer engine 7 notifies the status of the paper jam to a system program for controlling the entire printing apparatus and stops the paper feeding / discharging operation. . At this time,
A display for notifying the user that a paper jam has occurred is displayed on the operation panel 6, and a display for urging the user to clear the paper jam is displayed. When the paper is removed by the user and the paper jam is released, the printer engine 7 notifies the system program that controls the entire printing apparatus of the status of the paper jam release or the status of the ready state for printing. The notified system program re-forms the image data from the backup information of the page in which the paper jam has occurred, held in the RAM 3, and performs the printing process.

The operation of the present invention will be described below. FIG. 3 is a flowchart illustrating a first operation example of the printing apparatus according to the first embodiment of the present invention. When a paper jam occurs in the duplex printing mechanism, after the paper jam of the duplex printing mechanism is cleared (step S100 / YES), before starting the jam backup process, the user determines whether or not to release the duplex printing on the operation panel 6. Is displayed (step S101).

When the user selects release of double-sided printing on the operation panel 6 (step S102 / YE)
S), the double-sided printing mode in the backup information necessary to re-create the image data at the time of the jam backup processing is canceled (step S103). In addition, the duplex printing mode of the remaining pages until the end of the print job after the jam backup processing is also released (step S104).

Then, a jam backup process is performed using the backup information in which the double-sided printing mode has been released, and
Cancel double-sided printing and perform single-sided printing. After the jam backup processing, the remaining pages are also released from the double-sided printing until the end of the print job and are printed by the single-sided printing (step S105). If the user does not cancel the duplex printing on the operation panel 6 (step S102 / NO), the jam backup process is performed in the duplex printing mode as it is (step S105).

FIG. 4 is a flowchart showing a second operation example of the printing apparatus according to the first embodiment of the present invention. When a paper jam occurs in the duplex printing mechanism, the double-sided continuous paper jam occurrence count value of the double-sided continuous paper jam count recording unit 9 is incremented (1 is added) (step S).
200). After the paper jam of the two-sided printing machine is released (step S201 / YES), the value of the number of occurrences of the two-sided continuous paper jam and the value of the two-sided continuous paper jam limit number of the two-sided continuous paper jam limit number holding unit 11 are compared (step S20).
2).

If the double-sided continuous paper jam occurrence count value is smaller than the double-sided continuous paper jam limit count value (step S
202 / NO), a jam backup process is performed, and a printing process is started (step S203). If the paper printed by the jam backup processing ends normally without causing a paper jam (step S204 / NO), the value of the occurrence count of double-sided continuous paper jam is cleared (set to 0).
Then, the next page is printed (step S20).
5).

If the paper printed by the jam backup process causes paper jam again by the double-sided printing mechanism (step S204 / YES), step S200 is performed.
Then, the value of the double-sided continuous paper jam occurrence count value is incremented (1 is added) (step S200). As described above, when a paper jam occurs continuously from the same page in the double-sided printing mechanism, the double-sided continuous paper jam occurrence count value is incremented (1 is added).

In the comparison between the double-sided continuous paper jam occurrence count value and the double-sided continuous paper jam limit count value after the paper jam of the double-sided printing mechanism is released, the double-sided continuous paper jam occurrence count value is the same as the double-sided continuous paper jam limit count value. If it is larger (step S202 / YES), whether the double-sided printing is released on the operation panel 6 after the paper jam of the double-sided printing mechanism is released and before the jam backup process is started, similarly to the first operation example. Is displayed to allow the user to select cancellation of double-sided printing (step S206).

Thereafter, as in the first operation example, when the user selects cancellation of double-sided printing on the operation panel 6 (step S207 / YES), a backup necessary for re-forming image data at the time of jam backup processing is performed. Release the duplex printing mode in the information (step S20)
8). In addition, the duplex printing mode of the remaining pages until the end of the print job after the jam backup processing is also released (step S209). Then, a jam backup process is performed using the backup information for which double-sided printing has been released,
Cancel double-sided printing and perform single-sided printing. After the jam backup process, the remaining pages are also released from the double-sided printing until the end of the print job and are printed by the single-sided printing (step S210). Then, the value of the occurrence number of double-sided continuous paper jams is cleared (set to 0) (step S20).
5), end.

If the user does not cancel the double-sided printing on the operation panel 6 (step S207 / NO), the jam backup process is performed in the double-sided printing mode (step S203). In this way, when the same page continuously causes the paper jam more than the specified number of times in the double-sided printing mechanism, the double-sided printing is released and the printing can be performed by the single-sided printing.
The remaining pages up to the end of the print job can also be printed by single-sided printing by releasing double-sided printing.

FIG. 5 is a flowchart showing a third operation example of the printing apparatus according to the first embodiment of the present invention. In the second operation example, the number of double-sided continuous paper jam occurrences when the paper jam occurs continuously in the double-sided printing mechanism on the same page is counted. However, in the third operation example, the occurrence of paper jam in one print job is performed. The number of paper jam occurrences in the double-sided printing mechanism is counted.

After the start of the print job, the page printing process starts (step S300). If a paper jam has occurred in the duplex printing mechanism (step S301 / YES),
The double-sided paper jam occurrence count value of the double-sided paper jam count recording unit 10 is incremented (step S302). After the paper jam in the duplex printing mechanism is released (step S3
03 / YES), the double-sided paper jam occurrence count value is compared with the double-sided paper jam limit count value of the double-sided paper jam limit count holding unit 12 (step S304).

If the double-sided paper jam occurrence count value is smaller than the double-sided paper jam limit count value (step S304 /
NO), a jam backup process is performed, and a printing process is started (step S305). When the paper printed by the jam backup processing ends normally without causing paper jam in the duplex printing mechanism (step S306 /
No), the page printing process ends (step S30).
7). When the print job is completed (step S308 / Y
ES), the double-sided paper jam occurrence count value is cleared (step S309), and the process ends. Unless the print job is completed (step S308 / NO), the process returns to step S300 to continue the page printing process (step S300).

If the paper printed by the jam backup process causes a paper jam again by the double-sided printing mechanism (step S306 / YES), step S302.
Then, the value of the double-sided paper jam occurrence count value is incremented (1 is added) (step S302).

In the comparison between the double-sided paper jam occurrence count value and the double-sided paper jam limit count value after clearing the paper jam in the double-sided printing mechanism, the double-sided paper jam occurrence count value is equal to or larger than the double-sided paper jam limit count value. (Step S
304 / YES), similarly to the first operation example, after clearing the paper jam of the duplex printing mechanism and before starting the jam backup process, a message as to whether or not the duplex printing is to be released is displayed on the operation panel 6, and the user is prompted. The user can select to cancel double-sided printing (step S310).

When the user selects cancellation of double-sided printing on the operation panel 6 (step S311 / YES), backup information necessary for re-creating image data at the time of jam backup processing is performed, similarly to the first operation example. The middle duplex printing mode is released (step S312). In addition, the duplex printing mode of the remaining pages until the end of the print job after the jam backup processing is also released (Step S).
313). Then, a jam backup process is performed using the backup information for which double-sided printing has been canceled, and printing is performed by single-sided printing by canceling double-sided printing (step S31).
4). After the jam backup process, until the end of the print job (NO in step S308), the remaining pages are also printed by single-sided printing by canceling double-sided printing. When the print job is completed (YES in step S308), the value of the double-sided paper jam occurrence count is cleared (step S309), and the process ends.

If the user does not cancel the double-sided printing on the operation panel 6 (step S311 / NO), the jam backup process is performed in the double-sided printing mode (step S305). In this way, when paper jam occurs more than the number of times specified in one job in the double-sided printing mechanism, double-sided printing is released and printing can be performed by single-sided printing. The remaining pages can also be printed by single-sided printing by canceling double-sided printing.

Next, a fourth operation example of the printing apparatus according to the first embodiment of the present invention will be described. In the fourth operation example, when a paper jam occurs in the double-sided printing mechanism, the setting of whether to enable or disable the functions of the first, second, and third operation examples is performed by the NV-RAM4 (other than the NV-RAM4). Any memory or storage device that can be read and written even when the power is turned off may be used.) The functions of the first, second, and third operation examples are executed according to the settings. If a value indicating validity is set, the function is executed, and if a value indicating invalidity is set, the function is not executed. The setting of whether to enable or disable the functions of the first, second, and third operation examples is set by an input instruction from the operation panel 6 of the printing apparatus or an instruction from a higher-level device.

Next, a second embodiment of the present invention will be described. FIG. 6 is a flowchart illustrating a first operation example of the printing apparatus according to the second embodiment. When a paper jam occurs in the punch mechanism, after the paper jam of the punch mechanism is cleared (step S400 / YES), before starting the jam backup process, the user is asked on the operation panel 6 whether or not to release the punch execution mode. Display for selection is performed (step S401).

When the user selects release of the punch execution mode on the operation panel 6 (step S402 /
YES), the double-sided printing mode in the backup information necessary for re-forming the image data at the time of the jam backup processing is canceled (step S103). In addition, the punch execution mode of the remaining pages until the end of the print job after the jam backup processing is also released (step S40).
4).

Then, a jam backup process is performed using the backup information for which the punch execution mode has been released, and printing is performed with the punch execution mode released. After the jam backup processing, the remaining pages are also released from the punch execution mode and printed until the end of the print job (step S
405). If the user does not cancel the punch execution mode on the operation panel 6 (step S402 / NO), the jam backup process is performed in the punch execution mode as it is (step S405).

FIG. 7 is a flowchart showing a second operation example of the printing apparatus according to the second embodiment of the present invention. If a paper jam has occurred in the punch mechanism, the punch mode continuous paper jam occurrence count value of the punch mode continuous paper jam count recording unit 13 is incremented (step S500). After the paper jam of the punch mechanism is released (step S501 / YES), the value of the number of times of continuous paper jam occurrence in the punch mode and the maximum number of times of continuous paper jam in the punch mode continuous paper jam limit holding unit 15 are compared (step S501). Step S502).

If the value of the number of continuous paper jam occurrences in the punch mode is smaller than the maximum number of continuous paper jams in the punch mode (step S502 / NO), a jam backup process is performed and the printing process is started (step S50).
3). If the paper printed by the jam backup process ends normally without causing paper jam (step S
504 / NO), the punch mode continuous paper jam occurrence count value is cleared, and the next page is printed (step S505).

If the paper printed by the jam backup process causes a paper jam again by the punch mechanism (step S504 / YES), the flow returns to step S500, and the value of the number of times of continuous paper jam occurrence in the punch mode is incremented (step S504). S500). As described above, when a paper jam occurs continuously from the same page in the punch mechanism, the value of the number of continuous paper jam occurrences in the punch mode is incremented.

In the comparison between the number of occurrences of continuous paper jam in the punch mode after the paper jam of the punch mechanism is released and the maximum number of continuous paper jams in the punch mode, the value of the number of continuous paper jams in the punch mode is limited to the maximum number of continuous paper jams in the punch mode. If it is equal to or larger than the numerical value (step S502
/ YES), similarly to the first operation example, after clearing the paper jam of the punch mechanism and before starting the jam backup process, a message is displayed on the operation panel 6 as to whether or not to cancel the punch execution mode. The release of the punch execution mode can be selected (step S506).

Thereafter, similarly to the first operation example, when the user selects the release of the punch execution mode on the operation panel 6 (step S507 / YES), it is necessary to re-create the image data during the jam backup processing. The punch execution mode in the backup information is released (step S508). Further, the punch execution mode of the remaining pages until the end of the print job after the jam backup processing is also released (step S509). Then, a jam backup process is performed using the backup information for which the punch execution mode has been released, and printing is performed with the punch execution mode released. After the jam backup process, the remaining pages are also released from the punch execution mode and printed until the end of the print job (step S510). Then, the punch mode continuous paper jam occurrence count value is cleared (step S50).
5), end.

If the user does not release the punch execution mode on the operation panel 6 (step S507 / N
O), the jam backup process is performed in the punch execution mode (step S503). in this way,
When a paper jam occurs more than the specified number of times for the same page in the punch mechanism, the punch execution mode is released so that printing can be performed, and the remaining pages after the jam backup process until the end of the print job are also punched. The execution mode can be canceled and printing can be performed.

FIG. 8 is a flowchart showing a third operation example of the printing apparatus according to the second embodiment of the present invention. In the second operation example, the number of continuous paper jam occurrences in the punch mode when the paper jam occurs continuously in the punch mechanism on the same page is counted. In the third operation example, the occurrence of the paper jam occurs in one print job. The number of paper jam occurrences in the punch mechanism is counted.

After the start of the print job, the page printing process starts (step S600). If a paper jam occurs in the punch mechanism (step S601 / YE
S), the punch mode sheet jam occurrence count value of the punch mode sheet jam count recording unit 14 is incremented (step S602). After the paper jam in the punch mechanism is released (step S603 / YES), the punch mode paper jam occurrence count value is compared with the punch mode paper jam limit count value of the punch mode paper jam limit count holding unit 16 (step S604). ).

If the value of the number of occurrences of the paper jam in the punch mode is smaller than the maximum value of the number of paper jams in the punch mode (step S604 / NO), a jam backup process is performed and the printing process is started (step S605). If the paper printed by the jam backup process ends normally without causing a paper jam in the punch mechanism (step S606 / NO), the page printing process ends (step S607). When the print job is completed (Step S608 / YES), the punch mode paper jam occurrence count value is cleared (Step S609), and the process ends. While the print job is not completed (step S608 / NO),
