Image Diagnosis Sheet-Width Control for Complete Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image diagnosis methods are limited by the size of the sheet used, leading to undiagnosed regions when the sheet width is smaller than the maximum printable width, potentially causing printing abnormalities.
Innovation Solution
An image diagnosis apparatus and method that supports users in setting appropriate sheet sizes by comparing the selected sheet width with the maximum printable width and notifying users of undiagnosed regions, ensuring comprehensive image diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sheet with smaller sheet width is used for image diagnosis, then the sheet can be easily accommodated in the feeder and handled conveniently, but an undiagnosed region is produced on the outer part of the sheet width
Solution Approach 1:
The control unit provides feedback to the user by displaying information about undiagnosed regions on the sheet. When a sheet with smaller width is selected, the system notifies the user that outer regions cannot be diagnosed, allowing informed decision-making about whether to proceed with diagnosis or choose a different sheet size.
Solution Approach 2:
Before the image diagnosis is executed, the control unit performs preliminary checking of the sheet width and determines in advance whether undiagnosed regions will be produced. This preliminary action allows the user to understand the limitations before the actual diagnosis occurs.
2Reliability
If a sheet with larger sheet width is used for image diagnosis, then the entire region can be diagnosed, but the sheet may not fit properly in the feeder or cause handling issues
Solution Approach 1:
The system provides feedback information to the user about the relationship between sheet width and diagnosis coverage. By displaying whether the selected sheet width is suitable for complete diagnosis or if it will cause feeding issues, the system enables users to make informed choices about sheet selection.
3Productivity
If the test pattern image is efficiently disposed on the diagnosis chart, then the diagnosis region is maximized, but an undiagnosed region is still produced on the outer part of the sheet when sheet width is smaller than maximum printable width
Solution Approach 1:
Even when the test pattern is efficiently disposed to maximize the diagnosis region, the system provides feedback to inform users that outer regions remain undiagnosed when using sheets with smaller width. This ensures users understand the limitation despite optimal pattern placement.

AI summary
An image diagnosis apparatus comprises diagnosis means for reading, by reading means, a sheet with an image formed conveyed from image forming means and diagnosing an abnormality of an apparatus by detecting an abnormality in a read image; setting means for performing setting relating to image diagnosis according to a user operation, and controlling means for supporting a user in setting a sheet more suitable as a sheet to be used in image diagnosis when performing setting for a sheet to be used in image diagnosis.
