Calibration Control Logic for Image Forming Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network-connected image forming systems, frequent and thoughtless calibration by multiple users leads to unnecessary deterioration of consumables, noise generation, and unintended changes in color settings, as existing solutions either allow user-initiated calibration or prioritize user requests over system maintenance.
Innovation Solution
An image forming system with an instruction input unit for calibration execution, a restriction setting unit to limit calibration, and a determination unit that allows calibration only when necessary, ignoring instructions when restricted, thereby reducing unnecessary calibration and maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If calibration is allowed to be performed freely by users, then user convenience and image quality maintenance are improved, but calibration frequency increases causing consumable deterioration and noise
Solution Approach 1:
The determination unit acts as an intermediary between the user's calibration request and the actual calibration execution. It receives calibration execution instructions from users, evaluates them against predetermined conditions (such as operation counts or time intervals), and only permits calibration when appropriate. This mediator function resolves the contradiction by maintaining user convenience for legitimate calibration needs while preventing excessive calibration that would deteriorate consumables.
Solution Approach 2:
The system implements feedback through the determination unit that continuously monitors operation counts, time intervals, and other conditions to decide whether to permit calibration. This feedback mechanism ensures calibration occurs only when necessary based on actual usage patterns, balancing user convenience with consumable preservation by adapting to real-time system state.
2Loss of substance
If calibration is restricted to prevent frequent execution, then consumable deterioration is reduced, but user convenience and image quality maintenance are compromised
Solution Approach 1:
The restriction policy is made dynamic rather than static. The determination unit adjusts calibration permission based on real-time conditions such as operation counts, time intervals since last calibration, and detected issues. This dynamic approach allows the system to adapt to varying usage patterns, permitting calibration when necessary while restricting it when unnecessary, thus resolving the contradiction between preventing consumable deterioration and maintaining user convenience.
3Reliability
If calibration is performed automatically without user restriction, then image quality is maintained, but unintended color changes occur when multiple users access the system
Solution Approach 1:
The determination unit serves as a mediator that receives calibration instructions from any user but filters them through predetermined conditions before execution. This ensures that even when multiple users access the system, calibration is only performed when conditions are appropriate, preventing unintended color changes while maintaining image quality through controlled, condition-based calibration execution.

AI summary
An image forming system including: an instruction input unit that allows a user to input a calibration execution instruction for performing a calibration; a restriction setting unit that sets a restriction setting that restricts performing the calibration; a determination unit that determines whether or not to restrict performing the calibration based on the restriction setting; and a control unit that performs the calibration in response to the execution instruction while the determination unit determines that the calibration is allowed to be performed, and ignores the execution instruction while the determination unit determines that the calibration is restricted from being performed.
