Image Forming Apparatus Setting Interruption Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image forming apparatuses face inconvenience due to the need to reconfigure settings every time they use the device, especially when settings are interrupted by unintended causes, leading to a lack of user-friendliness.
Innovation Solution
The apparatus includes an operation unit for receiving settings, a storage unit to store these settings, and a reproduction unit that restores the interrupted settings when the interruption is removed, allowing for seamless continuation of the user's desired configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auto-clear function is used to automatically clear settings after a predetermined time period, then the next user can avoid using outdated settings, but the current user must reconfigure settings every time they use the apparatus
Solution Approach 1:
The system performs preliminary action by detecting and storing setting operations before they are completed or interrupted. When an interruption occurs, the stored setting information is preserved and automatically restored later, preventing loss of user configuration work.
Solution Approach 2:
The system implements feedback by monitoring the setting operation status, detecting interruptions, and providing automatic restoration of settings. This closed-loop feedback mechanism ensures that user settings are preserved across interruptions without requiring manual reconfiguration.
2Adaptability or versatility
If the customization function is provided to enable users to freely configure initial settings, then users can set their preferred configurations, but users unfamiliar with the apparatus cannot easily customize settings
Solution Approach 1:
The system provides self-service by automatically detecting user setting operations and restoring them after interruptions without requiring user intervention. This eliminates the need for users to manually customize complex settings, as the system handles configuration preservation and restoration autonomously.
Solution Approach 2:
The system performs preliminary detection and storage of setting operations before interruptions occur, so that when users return to the apparatus, their settings are already restored. This preliminary action makes the system adaptable to user preferences without requiring users to understand or configure complex settings manually.
3Reliability
If settings are stored only when users are in a logged-in state within a predetermined time period, then user-specific settings can be preserved, but settings interrupted outside this time period or by unintended causes are not stored
Solution Approach 1:
The system dynamically adjusts its behavior based on the type of interruption detected. For unintended interruptions (such as power failures or system errors), the system automatically stores and restores settings, whereas for intended user actions (such as logout), it follows the predetermined time period rules. This dynamic response enhances both reliability and adaptability.
Solution Approach 2:
The system changes the storage parameter from 'only during logged-in state within predetermined time' to 'also during unintended interruptions'. This parameter change allows the system to preserve settings across a broader range of scenarios, including power failures and system errors, while maintaining user-specific setting preservation through authentication-based storage.

AI summary
An image forming apparatus capable of properly reproducing, even when a setting operation is interrupted by a cause unintended by a user, settings desired by the user, and thereby improving the user-friendliness. In a case where a cause of interruption of a job setting operation is generated at a timing other than a predetermined timing, information on the displayed screen and information on the job settings are stored. When the cause of interruption has been removed, the stored screen information and information on job settings are read out, and the interrupted state of the job setting operation is reproduced.
