Print Mechanism Fluid Ejection Rate Control via Component Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink-jet printers face challenges in maintaining print quality due to varying fluid ejection rates, as existing technologies lack efficient methods to adjust and control the fluid deposition based on replaceable printing components, leading to inconsistent image saturation and detail.
Innovation Solution
The implementation of a system where replaceable printing components, such as printheads and fluid reservoirs, are equipped with identifiers that store nominal fluid ejection rates, allowing the print mechanism to adjust the fluid ejection rate through a lookup table, enabling control over print quality modes like draft, normal, and best, by determining the appropriate fluid deposition based on the component's identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the amount of ink dropped is increased to improve image saturation and detail, then print quality is improved, but ink consumption increases and reservoir life decreases
Solution Approach 1:
The system dynamically adjusts the fluid ejection rate based on the operational state of replaceable printing components. The controller modifies ejection parameters in real-time according to component identifiers, enabling the system to transition between different print quality modes (draft, normal, best) and optimize ink consumption accordingly
Solution Approach 2:
The system changes the fluid ejection rate parameter based on component identifiers stored on replaceable printing components. By adjusting this critical parameter, the system can achieve different print quality levels and extend reservoir life by reducing ink consumption when high quality is not required
2Manufacturing precision
If the fluid ejection rate is fixed to maintain consistent print quality, then image saturation and detail are preserved, but adaptability to different replaceable components is reduced
Solution Approach 1:
The system uses feedback from identifiers on replaceable printing components to automatically adjust the fluid ejection rate. The controller reads component identifiers and uses this information to determine appropriate ejection parameters, ensuring both consistent print quality and compatibility with different component types and conditions
Solution Approach 2:
The system achieves universal compatibility with different replaceable printing components by using a standardized identifier system. The controller can interpret various component states (new, depleted, different types) through identifiers and automatically adjust operations accordingly, making the system adaptable to multiple component scenarios while maintaining consistent output
3Ease of operation
If draft and economy modes are made easily accessible, then user convenience is improved, but control over fluid deposition precision is reduced
Solution Approach 1:
The system performs self-service by automatically selecting and adjusting fluid ejection parameters based on component identifiers without requiring manual user intervention. The controller autonomously determines the appropriate print mode and ejection rate based on the state of the installed printing components, maintaining precision while simplifying operation
