Print Apparatus Conditional Data Deletion for Post-Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems delete print data after printing, even if post-processing like stapling is not completed, leading to the inability to reprint without re-saving the data, which is inefficient and requires additional effort from users.
Innovation Solution
An image processing apparatus with a control unit that allows for automatic deletion of print data after printing, ensuring that print data is not deleted if post-processing is not completed, enabling reprinting without re-saving the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If print data is automatically deleted after printing completion, then security is improved and memory resources are effectively used, but if post-processing is not completed, the print data cannot be reprinted without re-saving
Solution Approach 1:
The patent applies dynamics by making the data deletion behavior adaptive rather than fixed. The control unit dynamically determines whether to delete print data based on the completion status of post-processing operations. If post-processing completes successfully, the print data is deleted automatically; if post-processing fails or is not completed, the print data is retained. This dynamic adjustment resolves the contradiction between security (through automatic deletion) and reprinting capability (through conditional retention).
2Quantity of substance
If print data is deleted after printing, then memory resources are effectively used, but user effort increases due to need to re-save data for reprinting
Solution Approach 1:
The patent implements feedback by having the control unit monitor the completion status of post-processing operations and use this information to determine the deletion behavior. The system receives feedback about whether stapling or other post-processing was successfully completed, and adjusts its data retention policy accordingly. This feedback mechanism ensures that print data is only deleted when post-processing succeeds, preventing the need for users to re-save data and reducing time loss while still effectively managing memory resources.
3Adaptability or versatility
If post-processing is not completed for exceeding sheet limits, then printing flexibility is maintained, but print data deletion cannot occur
Solution Approach 1:
The patent applies preliminary action by checking the completion status of post-processing operations before executing the data deletion action. The control unit ensures that post-processing has been successfully completed as a prerequisite for deleting the print data. This preliminary verification maintains printing flexibility (allowing prints to proceed even when sheet limits are exceeded) while ensuring data deletion reliability (only deleting data when post-processing is confirmed complete).
Data Source
AI summary
A print apparatus is provided that executes a print using print data that is stored in the apparatus, and in addition to executing post-processing on output materials after the printing, deletes the corresponding print data when processing of the print job ends. Here, the print apparatus according to the embodiment deletes the corresponding print data only in a case when the post-processing to all the sheets or the like set in one print job successfully ends.
