Printer Platen Height Control via Print Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers face challenges in adjusting the table height to meet user-specific print quality requirements, leading to potential difficulties in achieving the desired print result.
Innovation Solution
A printer system that includes a platen movable in both up-down and front-rear directions, controlled by a processor and memory, which adjusts its height based on special print data containing height information, allowing users to specify the required platen height for optimal print quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table height is adjusted based on the height of the print medium detected by the detection mechanism, then the printer can adapt to different print medium heights, but it becomes difficult to adjust the table height in accordance with the quality of the print result required by the user
Solution Approach 1:
The patent applies dynamics by making the platen height adjustable and controllable during operation. The platen is moved to different heights based on platen height information included in the print data, allowing the system to dynamically adapt to different print quality requirements rather than being fixed at a single detection-based height.
Solution Approach 2:
The patent changes the parameter of platen height based on information provided in the print data. By receiving platen height information from the print data and moving the platen to the specified height, the system can adjust the printing parameters to achieve the required print quality for different application scenarios.
2Device complexity
If the platen height is fixed at a detection-based position, then the structure remains simple, but the printer cannot create print results of the quality required by the user
Solution Approach 1:
The patent makes the platen height adjustment mechanism universal by enabling it to accommodate both automatically detected heights and user-specified heights from print data. This multi-functionality allows the same mechanism to serve different purposes: automatic adaptation when quality requirements are not specified, and precise control when quality requirements are provided in the print data.
3Manufacturing precision
If the platen is moved to user-specified heights based on print data, then the print quality can be optimized, but the control system becomes more complex
Solution Approach 1:
The patent applies self-service by having the control system automatically process the platen height information included in the print data and move the platen to the appropriate height without requiring separate user intervention. The system serves itself by extracting and acting on the height information already present in the incoming print data.

AI summary
A printer includes a head ejecting ink from a nozzle, a platen including a placement surface on which a print medium is placed, a receiver receiving print data, and a processor. The platen moves in a movement direction between a setting position where the print medium is placed on the placement surface and a printing position where the placement surface faces the nozzle surface in a facing direction. The movement direction is orthogonal to the facing direction. The platen moves in the facing direction. The processor moves the platen to a specified height when special print data is received by the receiver. The special print data is the print data including height information indicating a platen height. The platen height is a position of the platen in the facing direction. The specified height the platen height indicated by the height information included in the special print data.
