Abstract

Printing is performed based on a print job received from an information processing apparatus, the information processing apparatus is notified of a jam based on occurrence of the jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus. A scanned image obtained by scanning a printed print product is transmitted to an inspection apparatus, and information indicating that an inspection result obtained by the inspection apparatus inspecting a quality of the print product is “fail” is received. Based on the reception of the information indicating the inspection result “fail”, the information processing apparatus is notified of a jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus.

First claim

What is claimed is:

1. An inspection system including a printing apparatus, an inspection apparatus that inspects a quality of a print product printed by the printing apparatus, and an information processing apparatus that transmits a print job to the printing apparatus,
wherein the inspection apparatus comprises:
a reception unit configured to receive, from the printing apparatus, a scanned image obtained by scanning a print product printed by the printing apparatus;
an inspection unit configured to inspect a quality of the print product based on comparison between the received scanned image and a reference image; and
a transmission unit configured to transmit, based on an inspection result obtained by the inspection unit inspecting the quality of the print product, information indicating that an inspection result is failure to the printing apparatus,
wherein the printing apparatus comprises:
a printing unit configured to perform printing based on a print job received from the information processing apparatus;
a notification unit configured to notify the information processing apparatus of a first jam based on occurrence of the jam; and
the reception unit configured to receive the information indicating that the inspection result is failure from the inspection apparatus,
wherein, based on the reception of the information indicating that the inspection result is failure, the notification unit further notifies the information processing apparatus of a second jam, and
wherein the information processing apparatus comprises a transmission unit configured to, based on reception of the notification of the first jam or the second jam, transmit to the printing apparatus a reprint job for performing reprinting from an image corresponding to a sheet which has jammed.

2. The inspection system according to claim 1 , wherein the printing apparatus further comprises a control unit configured to control a sheet discharge destination of the print product based on the inspection result obtained by the inspection unit inspecting the quality of the print product.

3. The inspection system according to claim 1 ,
wherein the reception unit of the printing apparatus further receives inspection resumption information from the inspection apparatus, and
wherein the printing apparatus further comprises a clearing unit configured to clear a jam based on the received inspection resumption information.

4. The inspection system according to claim 3 ,
wherein the reception unit of the inspection apparatus further receives printing stop information from the printing apparatus, and
wherein, after the reception unit of the inspection apparatus receives the printing stop information, and in a case where the inspection apparatus enters a state where the inspection apparatus can perform an inspection, the transmission unit of the inspection apparatus transmits the inspection resumption information to the printing apparatus.

5. The inspection system according to claim 1 , wherein, in a case where the inspection unit detects the inspection result fail a predetermined number of times in succession, the transmission unit of the inspection apparatus transmits inspection stop information to the printing apparatus.

6. A printing apparatus comprising:
a printing unit configured to perform printing based on a print job received from an information processing apparatus;
a notification unit configured to notify the information processing apparatus of a first jam based on occurrence of the jam;
a transmission unit configured to transmit to an inspection apparatus a scanned image obtained by scanning a print product printed by the printing unit; and
a reception unit configured to receive, from the inspection apparatus, information indicating that the inspection result is failure,
wherein, based on the reception of the information indicating that the inspection result is failure, the notification unit further notifies the information processing apparatus of a second jam, and
wherein the reception unit further receives, from the information processing apparatus, a reprint job for performing reprinting that is generated based on the notification of the first jam or the second jam given by the notification unit.

7. The printing apparatus according to claim 6 , further comprising a control unit configured to control a sheet discharge destination of the print product based on the inspection result obtained by the inspection apparatus inspecting the quality of the print product.

8. The printing apparatus according to claim 6 ,
wherein the reception unit further receives inspection resumption information from the inspection apparatus, and
wherein the printing apparatus further comprises a clearing unit configured to clear a jam based on the received inspection resumption information.

9. A control method for controlling a printing apparatus, the control method comprising:
performing printing based on a print job received from an information processing apparatus;
notifying the information processing apparatus of a first jam based on occurrence of the jam;
transmitting to an inspection apparatus a scanned image obtained by scanning a printed print product;
receiving, from the inspection apparatus, information indicating that the inspection result is failure;
notifying the information processing apparatus of a second jam based on the reception of the information indicating that the inspection result is failure; and
receiving, from the information processing apparatus, a reprint job for performing reprinting that is generated based on the notification of the first jam or the second jam.

10. The control method for controlling the printing apparatus according to claim 9 , the control method further comprising controlling a sheet discharge destination of the print product based on the inspection result obtained by inspecting the quality of the print product.

11. The control method for controlling a printing apparatus according to claim 9 , the control method further comprising:
receiving inspection resumption information from the inspection apparatus, and
clearing a jam based on the received inspection resumption information.
