Image Carrier Concentration Correction via Segmented Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies face challenges in concentration correction due to increased friction and toner waste, leading to inaccurate results and unnecessary toner consumption, primarily caused by the close spacing of patterns on the image carrier which results in premature or lagging voltage switching errors.
Innovation Solution
The method involves rotating an image carrier with distinct regions for forming images, allowing a preset distance between image forming modules to control voltage switching, thereby increasing the spacing between patterns and reducing switching control difficulty, improving concentration correction stability and avoiding toner waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If patterns are arranged with small spacing on the image carrier to fit more patterns per page, then the quantity of patterns that can be formed is improved, but the allowable switching time between adjacent voltage levels is reduced, leading to voltage switching errors
Solution Approach 1:
The image carrier is divided into multiple regions, with each region dedicated to forming patterns for a specific color or set of patterns. This segmentation allows each region to have optimized spacing for its specific patterns, preventing voltage switching errors while maximizing the total number of patterns that can be formed per page.
Solution Approach 2:
The patent utilizes the radial dimension of the rotating image carrier to arrange patterns in concentric circles rather than only linearly along the page length. This allows patterns to be distributed in multiple dimensions (radial and angular), increasing the total quantity of patterns that can be formed without reducing the spacing between adjacent patterns, thereby maintaining reliable voltage switching.
2Duration of action of stationary object
If a time interval is introduced between forming first and second toner images to reduce friction, then the toner cartridge wear is reduced, but the concentration correction accuracy is compromised due to residual toner effects
Solution Approach 1:
The patent forms patterns for different colors or different sets of patterns continuously on the rotating image carrier without introducing time intervals. The image carrier rotates continuously, and patterns are formed in successive regions as it passes through the imaging zone, eliminating interruptions that would cause residual toner issues while maintaining accurate concentration correction.
Solution Approach 2:
The patent uses different regions on the image carrier as intermediaries to separate the formation of different toner images. Each region acts as a dedicated zone for specific patterns, allowing continuous formation without toner carryover between different pattern sets, thus maintaining both efficiency and accuracy.
3Productivity
If four color toner cartridges form patterns on the same page to reduce the number of pages needed, then the productivity is improved, but the spacing between adjacent patterns becomes too small, causing sensor detection errors
Solution Approach 1:
The image carrier is segmented into multiple regions, with each region dedicated to forming patterns for a specific color or set of patterns. This segmentation allows each region to have optimized spacing for its specific patterns, preventing voltage switching errors while maximizing the total number of patterns that can be formed per page.
Solution Approach 2:
The patent utilizes the radial dimension of the rotating image carrier to arrange patterns in concentric circles rather than only linearly along the page length. This allows patterns to be distributed in multiple dimensions (radial and angular), increasing the total quantity of patterns that can be formed without reducing the spacing between adjacent patterns, thereby maintaining reliable voltage switching.
