Fixer Identification for Gamma Correction Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image formation devices require time-consuming and labor-intensive processes to generate new gamma correction data every time a fixer is replaced, as the stored data is specific to each type of fixer, leading to increased workload and downtime.
Innovation Solution
An image formation device with a fixer identification system, a color sensor for reading gamma correction charts, and a memory to store associated gamma correction data, allowing for automatic generation and retrieval of gamma correction data based on the fixer and paper type, eliminating the need for manual data regeneration during fixer replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gamma correction data is stored specific to each fixer type, then printer gamma correction accuracy is improved, but the workload and time required for fixer replacement increases
Solution Approach 1:
The system performs preliminary actions by pre-storing gamma correction data for multiple fixer types in the memory medium before replacement occurs. When a fixer is replaced, the fixer identification portion automatically detects the new fixer type and retrieves the corresponding pre-stored gamma correction data, eliminating the need for time-consuming data regeneration and enabling immediate resumption of accurate printing operations
Solution Approach 2:
The system dynamically adapts to different fixer types through the fixer identification portion that automatically detects which fixer is mounted. The gamma correction data generating portion then dynamically selects and applies the appropriate gamma correction data corresponding to the detected fixer type, allowing the system to flexibly adjust to various fixer configurations without manual intervention
2Manufacturing precision
If gamma correction data is stored specific to each fixer type, then output image quality is improved, but device complexity increases
Solution Approach 1:
The memory medium serves multiple functions by storing both the fixer identification information and the corresponding gamma correction data for multiple fixer types within a single storage component. This universal storage approach consolidates what could be separate systems, maintaining high output image quality across different fixer types while avoiding the complexity of multiple independent data management systems
Solution Approach 2:
The fixer identification portion acts as an intermediary between the physical fixer and the gamma correction data. It automatically detects the fixer type and retrieves the corresponding pre-stored gamma correction data from memory, serving as a mediator that simplifies the interaction between the variable fixer component and the fixed gamma correction requirements, thereby reducing system complexity while maintaining precision
