Roll Sheet Printer Control for Cutting Failure Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional printers, cutting failures of roll sheets during image formation result in wasteful consumption of sheet media and image forming agents, as the process is interrupted and the partially formed sheets are manually handled, leading to inefficiency and resource waste.
Innovation Solution
An image forming apparatus with a conveyor, image forming part, cutting part, signal outputting part, and controller that continues image formation without interruption and reports cutting failures, allowing for manual intervention when necessary, thereby reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image forming process is interrupted when a cutting failure is detected, then the user can manually handle the sheet medium, but the sheet medium and image forming agent are consumed wastefully
Solution Approach 1:
The image forming process continues without interruption even when a cutting failure is detected. The controller maintains the conveying and image forming operations, allowing the sheet medium to be fully utilized despite the cutting issue, thereby eliminating wasteful consumption of both sheet medium and image forming agent.
2Ease of operation
If the image forming process is interrupted when a cutting failure is detected, then the user can manually handle the sheet medium, but the image forming agent is consumed wastefully
Solution Approach 1:
The image forming process continues without interruption even when a cutting failure is detected. The controller maintains the conveying and image forming operations, allowing the image forming agent to be utilized effectively on the sheet medium, thereby eliminating wasteful consumption of the image forming agent.
3Loss of substance
If the image forming process is continued without interruption after a cutting failure, then resource waste is reduced, but the user may not be aware of the cutting issue
Solution Approach 1:
The controller detects when a sheet medium has not been cut properly and provides feedback by notifying the user through the reporting part. This allows the image forming process to continue without interruption while keeping the user informed of the cutting issue, enabling them to address it appropriately without causing resource waste.
4Loss of substance
If the image forming process is continued without interruption after a cutting failure, then resource waste is reduced, but the user may not be aware of the cutting issue
Solution Approach 1:
The controller detects when a sheet medium has not been cut properly and provides feedback by notifying the user through the reporting part. This allows the image forming process to continue without interruption, preventing wasteful consumption of image forming agent, while keeping the user informed of the cutting issue.

AI summary
An image forming apparatus includes: a conveyor conveying a sheet medium; an image forming part forming an image on the sheet medium; a cutting part; a signal outputting part outputting a state signal; a reporting part; and a controller. The controller executes: an image forming process of conveying the sheet medium by the conveyor and forming the image on the sheet medium by the image forming part, and a cutting process of moving the cutting part. In a case where the sheet medium has not been cut even though the cutting process was executed during image formation on the sheet medium in the image forming process, the controller continues the image formation without interruption and causes the reporting part to report information regarding a failure of cutting of the sheet medium.
