Printing Apparatus Discharge Control for Error Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses often cancel processing for subsequent pages without user input when an error is predicted, leading to results that do not align with the user's intent and requiring cumbersome user interaction for repeated error responses.
Innovation Solution
A printing apparatus with a determination unit that assesses discharge conditions and identifies alternative processing instructions, allowing the execution of user-intended processing by switching discharge destinations and executing pre-instructed alternative actions, thereby reducing user operational input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printing apparatus automatically cancels processing for subsequent pages when an error is predicted, then the reliability of error handling is improved, but the user's intent may not be respected and operational input becomes cumbersome
Solution Approach 1:
The system performs preliminary error prediction by interpreting one page's worth of data before printing each page. When an error is predicted, the system has already prepared alternative processing options in advance, allowing it to present these options to the user before canceling the job, thus respecting user intent while maintaining reliable error handling.
Solution Approach 2:
The system implements feedback by presenting alternative processing options to the user when an error is predicted. The user's selection of alternative processing is fed back into the system, which then executes the chosen alternative rather than automatically canceling, thereby maintaining reliability while reducing operational burden.
2Adaptability or versatility
If the printing apparatus presents alternative processing options to the user for each error, then the user's intent is respected, but the operational input becomes cumbersome and time-consuming
Solution Approach 1:
The system applies partial action by presenting alternative processing options only when an error is predicted, rather than for every printing operation. This selective approach respects user intent for error scenarios while avoiding unnecessary operational input for normal operations, reducing overall time loss.
3Ease of operation
If the printing apparatus automatically executes a default alternative processing, then the operational input is reduced, but the user's specific intent may not be fulfilled
Solution Approach 1:
The system enables self-service by allowing the user to pre-designate alternative processing options in advance. When an error is predicted, the system executes the pre-designated alternative automatically without requiring real-time user input, thus reducing operational burden while fulfilling user intent through advance customization.

AI summary
A printing apparatus includes a first discharge unit to discharge a printing medium on which printing has been performed, and a second discharge unit to discharge a printing medium on which printing has been performed. A determination unit, in a case where the first discharge unit is instructed to be a discharge destination of a printing medium, determines whether to discharge the printing medium from the first discharge unit based on a predetermined condition. An identification unit, in a case where the determination unit determines not to discharge the printing medium from the first discharge unit, identifies alternative processing previously instructed by a user. An execution unit executes the alternative processing identified by the identification unit.
