Paper Tray Switching for Delayed Image Processing in Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face image formation failures due to delayed image processing operations, leading to incomplete images on paper sheets, especially when the processing time exceeds a predetermined duration.
Innovation Solution
The system switches paper sheet transportation from a first tray to a second tray that takes longer to transport sheets if the image processing operation is not completed within a predetermined time, allowing the image formation to continue without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the system uses a first tray with short transport time, then fast copy time is improved, but image formation failure occurs when image processing operation is delayed
Solution Approach 1:
The system changes the transport time parameter by switching between different trays (first tray with short transport time, second tray with long transport time) based on the completion status of the image processing operation. This parameter change allows the system to adapt to varying processing speeds and prevent image formation failures.
Solution Approach 2:
The system dynamically switches the paper sheet transport source between the first tray and second tray based on real-time monitoring of the image processing operation completion. This dynamic adjustment ensures that the transport time matches the actual processing time, preventing mismatches that cause image formation failures.
2Reliability
If the system waits for image processing operation to complete before transporting paper sheet, then image formation reliability is improved, but fast copy time increases
Solution Approach 1:
The system performs preliminary actions by starting paper sheet transport from the first tray before the image processing operation completes, based on a predetermined time estimation. If the processing completes in time, the image is formed successfully. If not, the system switches to the second tray as a backup, ensuring reliability without always waiting for completion.
Solution Approach 2:
The system takes a calculated risk by initiating transport before complete processing assurance, using the first tray for potential time savings. The excessive action is compensated by having the second tray ready as a backup, allowing the system to attempt faster operation while maintaining reliability through the fallback mechanism.
3Reliability
If the system switches to a second tray with longer transport time, then image formation reliability is improved, but fast copy time deteriorates
Solution Approach 1:
The system dynamically selects the appropriate tray based on the actual image processing operation duration. The first tray is used when processing is fast (maintaining high productivity), while the second tray is activated when processing is delayed (ensuring reliability). This dynamic selection optimizes the balance between productivity and reliability based on real-time conditions.

AI summary
An information processing apparatus includes a processor configured to: if an image processing operation generating an image to be formed on a paper sheet is not completed until a predetermined period of time elapses, switch transporting a paper sheet to an image former from a first tray to transporting a paper sheet to the image former from a second tray that takes a longer time to transport the paper sheet than the first tray.
