Selective Auto Color Registration Controller for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses unnecessarily perform auto color registration, leading to wastage of developing material and power consumption, as they always execute the process when auto color registration conditions are met, regardless of the printing mode.
Innovation Solution
An image forming apparatus with a controller that selectively performs auto color registration based on the printing mode, only executing the operation when the printing data is not in monochromatic mode and specific auto color registration conditions are satisfied, such as temperature discrepancies, high print volume, consumable replacement, or casing opening, adjusting image positions if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image forming apparatus always performs auto color registration when auto color registration conditions are satisfied, then color alignment accuracy is improved, but developing material is wasted and power is unnecessarily consumed
Solution Approach 1:
The patent changes the operational parameters of the auto color registration function by introducing printing mode as a control variable. The controller selectively enables or disables auto color registration based on whether the printing mode is color or monochromatic, thereby optimizing the balance between color alignment accuracy and developing material consumption.
2Manufacturing precision
If the image forming apparatus always performs auto color registration when auto color registration conditions are satisfied, then color alignment accuracy is improved, but power consumption increases unnecessarily
Solution Approach 1:
The patent modifies the operational parameters by making auto color registration conditional on the printing mode. The controller adjusts the execution state of auto color registration based on whether color printing is required, thereby reducing unnecessary power consumption while maintaining color alignment accuracy when needed.
3Extent of automation
If the image forming apparatus performs auto color registration in monochromatic printing mode, then processing completeness is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent applies local quality by making the auto color registration function applicable only to specific contexts (color printing mode) rather than universally. The controller locally activates this automated processing feature only where it provides value, thereby improving resource efficiency while maintaining processing completeness for color images.
Data Source
AI summary
An image forming apparatus to selectively perform an auto color registration operation, the apparatus including: a printing unit, which forms single-color images, based on printing data, and transfers the images to a printing medium to form a printed image; and a controller which prevents the printing unit from performing the auto color registration operation on the printing data, if the printing data relates a monochromatic printing mode.
