Abstract
A printing system is provided. The system comprises a printing unit for forming an image on a sheet transported along a transport path; an inspection unit for inspecting an image formed on the sheet transported along the transport path by comparing the image with a reference image, and for recording order information of sheets that have been inspected and order information of sheets that have been correctly discharged; and a control unit for, when a jam occurs in the transport path of the sheet, controlling the inspection unit to resume inspection, after printing resumes, from a first sheet recorded as not yet having been inspected or not correctly discharged.
Claims15
A printing system comprising a printing apparatus and an inspection apparatus, the inspection apparatus comprising:
- at least one processor;
- and
- at least one memory,
- wherein when a program stored in the at least one memory is executed by the at least one processor, the program causes the at least one processor to function as:
- a receiving unit that receives a scanned image obtained by reading along a conveying path a sheet on which an image has been formed;
- an inspection unit that performs inspection of the sheet on which the image has been formed by comparing the scanned image with a reference image;
- and
- a recording unit that records information identifying the discharged sheet and information identifying the inspected sheet in the memory, and
- the printing apparatus comprising:
- at least one processor;
- and
- at least one memory,
- wherein when a program stored in the at least one memory is executed by the at least one processor, the program causes the at least one processor to function as:
- a printing unit that forms an image on a sheet transported along the conveying path;
- a sheet discharging unit that discharges the inspected sheet from the conveying path;
- and
- a notification unit that notifies the inspection apparatus of information identifying the discharged sheet,
- wherein the inspection apparatus determines a page for which the inspection is resumed using the information identifying the inspected sheet and the information identifying the discharged sheet recorded by the recording unit in a case where a jam occurred in the conveying path of the sheet and printing is resumed.
A method of inspecting an image formed on a sheet transported along a transport path performed by a printing apparatus and an inspection apparatus, the method comprising:
- receiving, by the inspection apparatus, a scanned image obtained by reading along a conveying path a sheet on which an image has been formed;
- performing, by the inspection apparatus, inspection of the sheet on which the image has been formed by comparing the scanned image with a reference image;
- recording, by the inspection apparatus, information identifying the discharged sheet and information identifying the inspected sheet in a memory;
- forming, by the printing apparatus, an image on a sheet transported along the conveying path;
- discharging, by the printing apparatus, the inspected sheet from the conveying path;
- and
- notifying, by the printing apparatus, the inspection apparatus of information identifying the discharged sheets,
- wherein the inspection apparatus determines a page for which the inspection is resumed using the information identifying the inspected sheet and the information identifying the discharged sheet recorded in the recording in a case where a jam occurred in the conveying path of the sheet and printing is resumed.
A non-transitory computer-readable medium that stores a program that, when executed by a computer, causes the computer to carry out a method of inspecting an image formed on a sheet transported along a transport path, the method comprising:
- receiving a scanned image obtained by reading along a conveying path a sheet on which an image has been formed;
- performing inspection of the sheet on which the image has been formed by comparing the scanned image with a reference image;
- recording information identifying the discharged sheet and information identifying the inspected sheet in a memory;
- forming an image on a sheet transported along the conveying path;
- discharging the inspected sheet from the conveying path;
- and
- notifying an inspection apparatus of information identifying the discharged sheets,
- wherein a page for which the inspection is resumed is determined using the information identifying the inspected sheet and the information identifying the discharged sheet recorded in the recording in a case where a jam occurred in the conveying path of the sheet and printing is resumed.
