Image Quality Adjustment Control Skipping in Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses often execute unnecessary image quality adjustment controls due to conditions like elapsed time, number of printed sheets, or temperature changes, leading to time loss, consumable wastage, and component deterioration.
Innovation Solution
The apparatus selectively executes a first control mode for initial image quality adjustment and a second control mode that includes both adjustments, skipping the first mode if certain execution conditions are met, such as elapsed time or temperature changes being minimal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image quality adjustment control is executed based on elapsed time, number of printed sheets, or temperature change conditions, then image quality can be maintained under varying conditions, but unnecessary adjustments are performed causing time loss, consumable wastage, and component deterioration
Solution Approach 1:
The system continuously monitors multiple parameters (elapsed time, number of printed sheets, temperature change) and uses this feedback to dynamically determine whether image quality adjustment should be executed. By comparing current parameter values against threshold values, the system intelligently decides on adjustment execution, avoiding unnecessary operations while ensuring quality maintenance when needed.
Solution Approach 2:
The adjustment execution determination is made dynamically based on real-time parameter values rather than following a fixed schedule. The system adapts its behavior by evaluating current conditions (time elapsed since last adjustment, sheets printed since last adjustment, temperature change since last adjustment) and adjusts its operation accordingly, executing adjustments only when conditions warrant them.
2Reliability
If image quality adjustment control is executed frequently to maintain image quality, then image quality stability is improved, but consumable waste and component deterioration increase
Solution Approach 1:
The system uses feedback from multiple monitored parameters to determine adjustment necessity. By continuously tracking elapsed time, number of printed sheets, and temperature change, the system only executes adjustments when parameter thresholds indicate actual quality degradation risk, thereby avoiding unnecessary consumable consumption while maintaining quality stability.
Solution Approach 2:
The system monitors changes in multiple parameters (time, sheet count, temperature) and uses these parameter changes as triggers for adjustment execution. By setting appropriate threshold values for each parameter, the system optimizes the balance between maintaining image quality stability and reducing consumable waste, executing adjustments only when parameter changes indicate genuine quality issues.
3Ease of operation
If image quality adjustment control is executed based on fixed conditions, then execution simplicity is maintained, but adaptability to varying operating conditions deteriorates
Solution Approach 1:
The system dynamically evaluates multiple operating parameters (elapsed time, number of printed sheets, temperature change) to determine adjustment execution, rather than following a fixed schedule. This dynamic approach allows the system to adapt to varying operating conditions while maintaining relatively simple control logic based on threshold comparisons.
Solution Approach 2:
The adjustment execution determination mechanism serves multiple functions by simultaneously considering time-based, volume-based, and temperature-based conditions. This multi-functional approach enables the system to adapt to various operating scenarios (different printing volumes, environmental conditions, usage patterns) while using a unified control framework, achieving both simplicity and adaptability.

AI summary
An image forming apparatus includes an image forming device and circuitry. The image forming device forms an image on a recording material. The circuitry executes image quality adjustment control for adjusting image quality of the image formed by the image forming device. The circuitry is configured to selectively execute a first control mode for executing first image quality adjustment control and a second control mode including both the first image quality adjustment control and second image quality adjustment control. The circuitry executes only the second image quality adjustment control without executing the first image quality adjustment control in a case in which an execution skip condition for skipping the first image quality adjustment control is satisfied even when an execution condition for executing the second control mode is satisfied.
