Abstract
An image forming apparatus is configured to communicate with an external controller configured to generate a job, and includes one or more controllers having one or more processors and one or more memories, the one or more controllers being configured to acquire an image from a first job upon receiving the first job from the external controller and register a reference image generated from the image, to execute inspection processing upon receiving a second job from the external controller, and to perform control to delete the reference image registered upon receiving a cancellation instruction to cancel the second job from the external controller.
Claims19
An image forming apparatus configured to communicate with an external controller configured to generate a job, the image forming apparatus comprising:
- one or more controllers having one or more processors and one or more memories, the one or more controllers configured to:
- acquire an image from a first job upon receiving the first job from the external controller and register a reference image generated from the image;
- execute inspection processing for inspecting a printed image acquired from a second job based on the printed image and the reference image registered, upon receiving the second job from the external controller;
- and
- suspend the inspection processing and delete the reference image registered upon receiving a cancellation instruction to cancel the second job from the external controller.
A method for controlling an image forming apparatus configured to communicate with an external controller configured to generate a job, the method comprising:
- acquiring an image from a first job upon receiving the first job from the external controller and registering a reference image generated from the image;
- executing inspection processing for inspecting a printed image acquired from a second job based on the printed image and the reference image registered, upon receiving the second job from the external controller;
- and
- suspending the inspection processing and deleting the reference image registered upon receiving a cancellation instruction to cancel the second job from the external controller.
An external controller configured to communicate with an image forming apparatus having an inspection function, the external controller comprising:
- one or more controllers having one or more processors and one or more memories, the one or more controllers configured to:
- transmit a first job for causing the image forming apparatus to register a reference image to the image forming apparatus;
- receive identification information with respect to the reference image from the image forming apparatus;
- transmit a second job for causing the image forming apparatus to execute inspection processing to inspect a printed image acquired from the second job based on the printed image and the reference image registered, and to which the identification information received is added to the image forming apparatus;
- and
- transmit a cancellation instruction to suspend the inspection processing and delete the reference image registered in the image forming apparatus to the image forming apparatus in a case where the second job is cancelled.
A method for controlling an external controller configured to communicate with an image forming apparatus having an inspection function, the method comprising:
- transmitting a first job for causing the image forming apparatus to register a reference image;
- receiving identification information with respect to the reference image from the image forming apparatus;
- transmitting a second job for causing the image forming apparatus to execute inspection processing to inspect a printed image acquired from the second job based on the printed image and the reference image registered, and to which the identification information received is added;
- and
- transmitting a cancellation instruction to suspend the inspection processing and delete the reference image registered in the image forming apparatus to the image forming apparatus in a case where a cancellation instruction to cancel the second job is issued.
A method for controlling a system including an image forming apparatus configured to communicate with an external controller configured to process a job, the method comprising:
- acquiring an image from a first job upon receiving the first job and registering a reference image generated from the image;
- controlling execution of inspection processing for inspecting a printed image acquired from a second job based on the printed image and the reference image registered, upon receiving the second job;
- and
- causing a computer to execute processing for suspending the inspection processing and deleting the registered reference image in a case where a cancellation instruction to cancel the second job is received.
