Density Classifiers for Plane Regions in Print Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices face operational issues such as skew and paper jams due to media distortion caused by varying print fluid densities, which affect the movement and speed of media along the print path, particularly in sensitive areas like corners.
Innovation Solution
A system that adjusts print device components based on print fluid density using a density engine and component engine, which classify regions on the printing plane and adjust attributes like print speed and fluid flow to compensate for distortion, ensuring proper media movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If media is printed with varying print fluid densities, then print quality and content coverage are improved, but media distortion occurs causing skew and paper jams
Solution Approach 1:
The printing plane is divided into multiple regions, with at least one sensitive region identified where distortion is more likely to occur. The system segments the media into different zones and applies region-specific adjustments to print fluid density, allowing high print quality in non-sensitive areas while reducing or avoiding printing in sensitive regions to prevent distortion and operational failures.
Solution Approach 2:
The system applies different print fluid densities to different regions of the media based on their sensitivity characteristics. Sensitive regions receive reduced or zero print fluid application, while non-sensitive regions receive normal or enhanced printing. This local differentiation resolves the contradiction by maintaining overall print quality while preventing distortion in critical areas.
2Productivity
If print speed is increased to improve productivity, then output efficiency is improved, but media distortion causes skew and paper jams reducing reliability
Solution Approach 1:
The system dynamically adjusts print speed based on the detected sensitivity of different media regions. When sensitive regions are identified, the print speed is automatically reduced for those specific areas to prevent distortion, while maintaining higher speeds in non-sensitive regions. This dynamic adaptation allows the system to achieve high overall productivity while ensuring reliability in critical zones.
3Device complexity
If uniform print fluid density is applied across the entire plane, then printing process simplicity is maintained, but distortion in sensitive areas like corners causes operational issues
Solution Approach 1:
The system automatically segments the printing plane into sensitive and non-sensitive regions based on media characteristics and print job requirements. This segmentation enables region-specific print fluid density control without requiring manual intervention or complex user configuration, thus maintaining process simplicity while improving reliability through targeted adjustments in sensitive areas.
Data Source
AI summary
In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.
