Printer Scanner Aligns Print Area to Frame Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers struggle to accurately print data within a designated range on materials with pre-existing frame lines, leading to potential misalignment and incomplete printing.
Innovation Solution
A printer equipped with a processor and scanner that detects frame lines on the material and sets a print area, allowing the print head to align and print within this area, ensuring accurate placement and completion of printing tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printer moves manually in the main scanning direction, then the ease of operation is improved, but the manufacturing precision deteriorates due to difficulty in accurately printing within the designated range
Solution Approach 1:
The scanner performs preliminary scanning of the material surface to detect frame lines and calculate the print area before the actual printing operation begins. This preliminary detection and calculation enables the system to adapt the print parameters to the actual material layout, ensuring accurate printing even when the printer is moved manually by the user.
2Productivity
If the print area is set without detecting frame lines, then the productivity is improved, but the manufacturing precision deteriorates due to potential misalignment with the designated range
Solution Approach 1:
The printing process is segmented into distinct phases: first, the scanner rapidly scans the material surface to detect frame lines and calculate the print area; second, the processor processes the scanned image data to determine precise print boundaries; third, the print head executes printing within the calculated area. This segmentation allows the system to maintain high productivity through efficient scanning while ensuring precision through dedicated image processing and adaptive print area calculation.
Data Source
AI summary
A printer includes: a processor; a print head configured to perform printing in accordance with input print data; and a scanner configured to acquire an image of a material to be printed. The processor is configured to detect at least one line extending in a first direction on the material to be printed from the image acquired by the scanner when moving of the printer in a moving direction in which the scanner is on the front side of the print head, and set a print area along the first direction based on the line on the material to be printed, and the print head prints in the print area.
