Image Forming Apparatus Setting Value Confirmation Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses overwrite user-configured settings when a registered job program is called, potentially leading to unintentional overwriting of user settings.
Innovation Solution
An image forming apparatus that displays a confirmation screen asking the user if they want to discard changed setting values and update them with batch setting values from a job program, allowing the user to choose whether to update or maintain their settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batch setting values are automatically updated without confirmation, then productivity is improved by simplifying the job program calling process, but reliability deteriorates due to potential unintentional overwriting of user settings
Solution Approach 1:
The system applies preliminary anti-action by detecting changes in setting values before the batch setting is called and proactively preventing potential overwriting through a confirmation prompt. This anticipates the harmful effect (unintentional overwriting) and counteracts it before it occurs, allowing automatic updating when no changes are detected while protecting user settings when changes are present.
Solution Approach 2:
The system implements feedback by monitoring and comparing setting values between the execution screen and batch setting, then providing information feedback to the user through a confirmation prompt when differences are detected. This feedback mechanism enables the system to adapt its behavior based on the user's response, balancing automatic efficiency with user control.
2Reliability
If a confirmation screen is displayed before updating settings, then reliability is improved by preventing unintentional overwriting, but ease of operation deteriorates due to additional user interaction steps
Solution Approach 1:
The system applies partial action by displaying the confirmation prompt only when necessary - specifically when setting values have been changed since the batch setting was registered. When no changes are detected, the system proceeds with automatic updating without requiring user interaction. This selective application of confirmation reduces unnecessary steps while maintaining protection when needed.
3Productivity
If setting values are automatically overwritten with batch settings, then productivity is improved by streamlining the job execution process, but loss of information occurs when user-modified settings are discarded
Solution Approach 1:
The system performs preliminary action by detecting and preserving user-modified setting values before the batch setting is applied. By checking for changes in advance and maintaining a record of user modifications, the system can restore this information if the user chooses to cancel the batch setting update, thereby preventing information loss while still enabling efficient batch processing.

AI summary
An image forming apparatus includes a display, one or more storages, and one or more controllers. The display displays an execution screen on which first setting values related to execution of a job have been reflected. The one or more storages store therein second setting values related to execution of the job as a batch setting. The one or more controllers execute the job based on the batch setting. If any of the first setting values have been changed to third setting values before a calling instruction to call the batch setting is given, the one or more controllers display a confirmation screen presenting an inquiry to a user regarding whether or not to discard the third setting values and update the first setting values with the second setting values, and update the first setting values with the second setting values or the third setting values based on a result of the inquiry confirmed by the user.
