Print System Supply Interface Group Identifier Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Print systems face challenges in adapting operations and ensuring compatibility when a new print fluid supply is inserted, as they lack efficient methods to recognize and coordinate with the installed supply, leading to potential mismatches in color calibration and operational settings.
Innovation Solution
The implementation of a print system that utilizes a supply interface and controller to read and compare a group identifier from a machine-readable medium on the supply to a group reference, enabling operations such as color calibration and adjusting settings based on compatibility, with features like group flags and usage flags to manage supply usage and authorization levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the print system uses a simple supply interface without group identifier recognition, then the device complexity is reduced, but the adaptability to different supply types and the accuracy of color calibration deteriorate
Solution Approach 1:
The system performs preliminary recognition of the supply's group identifier upon insertion, before any printing operations begin. This preliminary action enables the controller to pre-configure appropriate operational settings and color calibration parameters specific to that supply group, ensuring optimal performance from the start without requiring complex real-time adjustments during operation.
Solution Approach 2:
The supply interface provides feedback to the controller about the inserted supply's group identifier through machine-readable identification. This feedback mechanism allows the controller to automatically adapt its operations and color calibration settings based on the specific supply type detected, enabling versatility without manual configuration while keeping the interface itself relatively simple.
2Manufacturing precision
If the print system performs color calibration for every new supply insertion, then the print quality is maintained, but the productivity is reduced due to time-consuming calibration operations
Solution Approach 1:
Instead of performing full color calibration for every supply insertion, the system applies local quality by performing calibration only when necessary - specifically when a new group identifier is detected or when the supply is first used. For subsequent insertions of supplies from the same group, the system reuses existing calibration settings, maintaining print quality while avoiding redundant calibration operations that would reduce productivity.
Solution Approach 2:
The system performs color calibration in advance when a new supply group is first inserted, storing the calibration results for future use. This preliminary calibration action ensures that when supplies from the same group are later inserted, the pre-established calibration settings can be applied immediately without time-consuming recalibration, thus maintaining both print quality and productivity.
3Reliability
If the print system tracks detailed supply usage and authorization levels, then the reliability of supply management is improved, but the device complexity increases
Solution Approach 1:
The supply interface and controller work together to automatically track supply usage and authorization levels without requiring external management systems. The machine-readable medium on each supply provides self-identifying information that the controller uses to automatically manage supply tracking, ensuring reliable supply management through automated processes rather than complex external systems.
Solution Approach 2:
The supply interface serves multiple functions: it physically connects the supply, reads the group identifier, tracks usage, and manages authorization levels. By consolidating these functions into a single multi-functional interface rather than separate dedicated systems for each function, the achieve reliable supply management while minimizing the increase in overall device complexity.
Data Source
AI summary
In an example, a print system is described and includes a supply interface to form electrical communication with a container of print fluid and a controller to retrieve data from a machine-readable medium coupled to the container, identify a container group identifier based on the retrieved data, and set a group flag based on a comparison of the container group identifier with data representing a group reference.
