Cover Closing Screen Control for Image Processing Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses do not effectively control the display of a cover closing screen when a user opens the cover during a maintenance method demonstration, leading to interruptions in print jobs if a job is in the execution queue, and fail to provide an optional reproduction mode for maintenance operations when no jam occurs.
Innovation Solution
An image processing apparatus with a first detection unit for maintenance events, a receiving unit for display instructions, a display control unit to manage screens based on detected events, and a sensing unit for cover states, which displays a cover closing screen only if a job exists when the cover is opened during a maintenance method demonstration, and allows optional reproduction of maintenance operations even without a detected jam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover closing screen is displayed when the cover is opened during a maintenance method demonstration, then the user is prompted to close the cover, but the demonstration is interrupted and user experience deteriorates
Solution Approach 1:
The system dynamically adjusts the display control based on the detected state (maintenance event occurrence). When a maintenance event is detected, the cover closing screen is suppressed during maintenance method display. When no maintenance event occurs, the screen is displayed normally. This dynamic adaptation resolves the contradiction by making the system behavior context-dependent.
Solution Approach 2:
The display control unit changes the display parameter (cover closing screen visibility) based on the maintenance event detection state. The parameter transitions between two states: displayed when no maintenance event occurs, and suppressed when a maintenance event is detected, thereby maintaining demonstration continuity while preserving normal operational warnings.
2Ease of operation
If the cover closing screen is suppressed during maintenance method display, then the demonstration continues smoothly, but print jobs in execution queue may be interrupted
Solution Approach 1:
The system dynamically determines whether to suppress the cover closing screen based on the detection of maintenance events. When a maintenance event is detected, suppression is applied to ensure demonstration continuity. When no maintenance event is detected, the screen is displayed to prevent job interruption. This dynamic decision-making resolves the contradiction by adapting system behavior to the actual operational context.
Solution Approach 2:
The image processing apparatus uses feedback from the maintenance event detection unit to control screen display behavior. The detection result feeds back to the display control unit, which adjusts the cover closing screen visibility accordingly. This feedback mechanism ensures that the system responds appropriately to maintenance needs while protecting print job execution.
3Productivity
If the cover closing screen is always displayed when the cover is opened, then print jobs are protected from interruption, but maintenance demonstrations are interrupted
Solution Approach 1:
The display control unit implements dynamic behavior by adjusting the cover closing screen visibility based on the maintenance event detection state. In normal operation mode, the screen is always displayed to protect print jobs. During maintenance method display (when maintenance event is detected), the screen is suppressed to maintain demonstration flow. This dynamic adaptation resolves the contradiction.
Solution Approach 2:
The system performs preliminary detection of maintenance events before displaying the maintenance method. This preliminary action allows the system to prepare the appropriate display behavior in advance, ensuring that the cover closing screen is suppressed only when necessary for maintenance demonstrations, while normally remaining visible to protect print job execution.
4Adaptability or versatility
If the system detects maintenance events and displays maintenance methods, then users can learn proper procedures, but the system complexity increases
Solution Approach 1:
The image processing apparatus integrates multiple functions into a unified system: maintenance event detection, maintenance method display, and cover closing screen control. The display control unit serves multiple purposes by adapting its behavior based on the detection state, providing both maintenance guidance and print job protection without requiring separate dedicated systems.
Solution Approach 2:
The system provides self-service maintenance guidance by automatically detecting maintenance events and displaying appropriate maintenance methods. The detection unit and display control unit work together to enable users to perform maintenance operations independently without external assistance, while the system manages the complexity internally through integrated control logic.

AI summary
An image processing apparatus includes a first detection unit that detects occurrence of a maintenance event, a receiving unit that receives a display instruction of a maintenance method corresponding to the maintenance event from a user, a display control unit that displays a first maintenance screen including an image illustrating the maintenance method and an instruction of opening a cover and exposing a portion where the maintenance event occurred and displays a second maintenance screen including an image illustrating the maintenance method and an instruction of opening the cover when occurrence of the maintenance event is not detected.
