Image Diagnosis Sheet-Width Guidance for Undiagnosed Regions
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 support users in setting a suitable sheet width for diagnosis by comparing the selected sheet width with a predetermined width and notifying users of undiagnosed regions, ensuring comprehensive image analysis.
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 handled and stored, but an undiagnosed region is produced on the outer part of the sheet width
Solution Approach 1:
The system provides feedback to the user by displaying information about undiagnosed regions when a sheet with smaller width is selected. This allows users to understand the consequences of their sheet selection and make informed decisions about whether to use a smaller sheet for ease of handling or a larger sheet for complete diagnosis coverage.
2Reliability
If a sheet with larger sheet width is used for image diagnosis, then complete image diagnosis can be performed, but the sheet may not fit in the determined region and a remainder region may be produced
Solution Approach 1:
The system performs preliminary control to determine the appropriate sheet width before the actual diagnosis process. By calculating and displaying information about undiagnosed regions in advance, the system prevents users from selecting sheets that would result in incomplete diagnosis or fit problems, thereby simplifying the overall process.
3Device complexity
If the diagnosis region is limited to the sheet width, then the diagnosis process is simple, but undiagnosed regions are produced when sheet width is smaller than maximum printable width
Solution Approach 1:
The system provides feedback information to users about the relationship between sheet width and diagnosis region. By displaying information about undiagnosed regions when smaller sheets are selected, the system maintains simple diagnosis processing while alerting users to potential information loss.

AI summary
An image diagnosis apparatus comprises one or more memory devices that store a set of instructions; and one or more processors that execute the set of instructions to: read, by a reading unit, a sheet having an image formed thereon by an image forming unit and diagnose an abnormality of the image forming unit by detecting an abnormality in a read image of the sheet, perform setting relating to a sheet width setting for a sheet to be used in image diagnosis according to a user operation, and support a user in setting a sheet width more suitable as a sheet to be used in image diagnosis when performing setting relating to a sheet width setting for a sheet to be used in image diagnosis.
