Adaptive Calibration Suspension for Image Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image-forming apparatuses suspend calibration processes to improve user convenience, but this can lead to significant printing without calibration, resulting in deterioration of image quality.
Innovation Solution
The image-forming apparatus suspends the calibration process during printing and forces it when a predetermined condition is met, such as a higher page threshold, to minimize image quality deterioration while allowing user control over when to prioritize image quality or processing speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the calibration process is suspended to improve user convenience, then user convenience is improved, but image quality deteriorates due to excessive printing without calibration
Solution Approach 1:
The patent applies dynamics by making the calibration suspension policy adjustable and adaptive. The control unit can dynamically change the suspension policy based on printing conditions, allowing the system to flex between strict calibration scheduling and user convenience based on real-time needs, rather than following a fixed rigid schedule
Solution Approach 2:
The patent changes the parameter of calibration suspension policy from a fixed state to a variable state. By allowing the suspension policy to be changed based on printing conditions and user preferences, the system can adjust the balance between calibration frequency and user convenience, transforming a static parameter into a dynamic control mechanism
2Manufacturing precision
If the calibration process is executed frequently to maintain image quality, then image quality is maintained, but processing time increases and user convenience deteriorates
Solution Approach 1:
The patent applies partial action by implementing selective calibration suspension. Instead of always executing calibration or never executing it, the system applies calibration only when necessary based on printing conditions, suspending it partially during periods when strict scheduling is not critical, thus reducing unnecessary processing time while maintaining quality when needed
3Productivity
If the calibration process is suspended without user control to improve processing speed, then processing speed is improved, but the user cannot control when image quality is prioritized
Solution Approach 1:
The patent implements feedback by allowing users to provide input that influences the calibration suspension policy. The control unit receives user input and adjusts the suspension policy accordingly, creating a closed-loop system where user preferences directly affect calibration timing, enabling users to control when image quality is prioritized over processing speed

AI summary
An image forming apparatus is capable of minimizing the deterioration of image quality by suspending a calibrating process in a predetermined case while improving user convenience. While in the suspended state, when a predetermined condition is satisfied, the multifunction machine can force the calibrating process in the print job, and when the predetermined condition is not satisfied, the calibrating process is not forced in the print job.
