Abstract
A diagnostic system may comprise an image forming apparatus that forms a diagnostic image on a sheet and an image capturing apparatus that captures an image of the sheet on which the diagnostic image is formed and which has been discharged from the image forming apparatus, and outputs the image captured as a sheet image. The image capturing apparatus may make a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image, and output a diagnosis result for the component of the image forming apparatus.
Claims24
A diagnostic system comprising:
- an image forming apparatus configured to form a diagnostic image on a sheet;
- and
- an image capturing apparatus configured to capture an image of the sheet on which the diagnostic image is formed and which has been discharged from the image forming apparatus, and outputs the captured image as a sheet image,
- wherein the image capturing apparatus comprises one or more processor configured to:
- make a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image;
- output a diagnosis result for the component of the image forming apparatus,
- obtain direction information pertaining to a direction in which the image forming apparatus forms the diagnostic image with respect to the sheet;
- and
- make the diagnosis for the component of the image forming apparatus using the direction information and the position of the image deficiency in the sheet image.
An image capturing apparatus comprising:
- an imaging sensor configured to capture an image of a sheet on which a diagnostic image has been formed by an image forming apparatus to be diagnosed, and outputs the captured image as a sheet image;
- and
- one or more processor configured to:
- make a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image;
- output a diagnosis result for the component of the image forming apparatus;
- obtain direction information pertaining to a direction in which the image forming apparatus forms the diagnostic image with respect to the sheet;
- and
- make the diagnosis for the component of the image forming apparatus using the direction information and the position of the image deficiency in the sheet image.
A non-transitory computer-readable storage medium storing a program for causing an image capturing apparatus to execute processing comprising:
- capturing an image of a sheet on which a diagnostic image has been formed by an image forming apparatus to be diagnosed, and outputting the captured image as a sheet image;
- making a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image;
- outputting a diagnosis result for the component of the image forming apparatus;
- obtaining direction information pertaining to a direction in which the image forming apparatus forms the diagnostic image with respect to the sheet;
- and
- making the diagnosis for the component of the image forming apparatus using the direction information and the position of the image deficiency in the sheet image.
A diagnostic system comprising:
- an image forming apparatus configured to form a diagnostic image on a sheet;
- an image capturing apparatus configured to capture an image of the sheet on which the diagnostic image is formed and which has been discharged from the image forming apparatus, and outputs the captured image as a sheet image;
- and
- a diagnostic apparatus configured to make a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image obtained by the image capturing apparatus, and outputs a diagnosis result for the component of the image forming apparatus,
- wherein the diagnostic apparatus is further configured to:
- obtain direction information pertaining to a direction in which the image forming apparatus forms the diagnostic image with respect to the sheet;
- and
- make the diagnosis for the component of the image forming apparatus using the direction information and the position of the image deficiency in the sheet image.
