Image Forming Apparatus Mismatch Correction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses perform frequent image corrections due to overestimation of mismatch, leading to unnecessary corrections and increased ink or toner consumption, as they rely on predefined conditions based on estimated mismatch ranges rather than actual variations.
Innovation Solution
An image forming apparatus with a processing unit and memory that measures and corrects image mismatch by acquiring variations in factors causing mismatch, estimating mismatch amounts, and altering calculation factors and reference values based on measured data to determine necessary corrections.

Engineering Contradiction Analysis
1Reliability
If image correction is performed frequently to maintain image quality, then image quality is improved, but ink or toner consumption increases and user convenience deteriorates
Solution Approach 1:
The system measures the actual amount of mismatch and uses this feedback to determine whether correction is necessary. The control section compares the measured mismatch amount against the reference value and only initiates correction when the mismatch exceeds the threshold, avoiding unnecessary corrections and associated resource consumption while maintaining image quality.
Solution Approach 2:
The system dynamically adjusts the reference value for mismatch based on acquired data about variation factors. By modifying the reference value parameter according to actual operating conditions and measured mismatch patterns, the system optimizes the balance between maintaining image quality and avoiding unnecessary corrections.
2Ease of operation
If predefined conditions based on estimated mismatch ranges are used to determine correction requirements, then correction decisions are simplified, but unnecessary corrections occur when estimated mismatch significantly differs from actual mismatch
Solution Approach 1:
The system replaces static predefined conditions with a dynamic feedback mechanism that measures actual mismatch amounts. The control section uses measured mismatch data to determine whether correction is necessary, which simplifies the decision-making process while improving accuracy and eliminating unnecessary corrections.
Solution Approach 2:
The system performs preliminary measurement of the mismatch amount before initiating correction. By measuring the actual mismatch and comparing it against the reference value in advance, the system avoids unnecessary corrections and optimizes productivity while maintaining simple operation.

AI summary
An image forming device includes an image forming section, a CPU and memory storing executable instructions that, when executed by the CPU, cause the image forming device to provide functions including a data acquisition section, a mismatch correction section and a control section. The data acquisition section is configured to acquire a variation in factor that causes a mismatch of a parameter. The control section is configured to estimate an amount of mismatch of the parameter based on the variation and to send a request for measuring the amount of mismatch to the mismatch correction section when the estimated amount is equal to or larger than a reference value. The control section is also configured to alter at least one of calculation factors used for estimating the amount of mismatch and the reference value according to the measured amount.
