Image Size Adjustment for Uninterrupted Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face interruptions when trying to print images of sizes that do not match the available paper sizes, as they need to stop the printing operation and require users to supply matching paper, leading to inefficiencies.
Innovation Solution
The apparatus can continue printing by setting the size of an image to match the available paper size using an automatic or manual output mode, allowing it to print on paper of a different size, ensuring continuous operation without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image forming apparatus prints images only when paper size matches image size, then printing quality is maintained, but printing operation is interrupted and productivity decreases
Solution Approach 1:
The patent applies dynamics by making the image size adjustable and adaptable based on available paper sizes. The image forming apparatus dynamically changes the output image size to match different paper sizes in the paper trays, allowing continuous printing operations without interruption while maintaining acceptable printing quality through scalable image rendering.
2Manufacturing precision
If the image forming apparatus stops printing when paper size mismatch occurs, then printing accuracy is maintained, but user intervention is required and operation complexity increases
Solution Approach 1:
The patent implements self-service by enabling the image forming apparatus to automatically detect available paper sizes and autonomously adjust the output image size accordingly. The system performs self-adjustment without requiring user intervention, automatically selecting appropriate paper trays and modifying image dimensions to match the available paper, thereby maintaining printing accuracy while eliminating the need for manual intervention.
3Manufacturing precision
If the image forming apparatus requires exact paper size matching, then image fidelity is preserved, but adaptability to different paper sizes decreases
Solution Approach 1:
The patent applies parameter changes by modifying the output image size parameter to match different paper sizes. The image forming apparatus changes the dimensional parameters of the output image according to the available paper sizes in the paper trays, allowing the system to adapt to various paper sizes while preserving image fidelity through proportional scaling and appropriate rendering adjustments.
