Image Forming Apparatus Split Print Orientation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses with poster printing functions face challenges in suppressing blank generation on the sides of sheets during enlargement printing, particularly when dealing with specific sheet sizes like A series and B series formats.
Innovation Solution
A printing system comprising a print setting apparatus and an image forming apparatus that exchanges vertical and horizontal directions of image formation for sheets with an aspect ratio of 1:1.41, enabling a split print mode that enlarges images onto two sheets, thereby reducing blank occurrence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image enlargement is performed on sheets with aspect ratio 1:1.41 using conventional split print mode, then image is printed on multiple sheets, but blanks are generated on the upper, lower, left, and right sides of the sheet
Solution Approach 1:
The patent applies inversion by exchanging the vertical and horizontal directions of image formation specifically for sheets with aspect ratio 1:1.41. Instead of printing the image in the conventional orientation, the system rotates the image 90 degrees, which allows the enlarged image to be properly positioned on the sheet without generating blanks on all four sides. This directional inversion resolves the contradiction between maintaining image integrity and eliminating wasted space.
2Adaptability or versatility
If conventional split print mode is used for enlarging images, then images can be printed on multiple sheets, but blank areas are created reducing printing efficiency
Solution Approach 1:
The patent applies local quality by implementing direction exchange only for specific sheet sizes with aspect ratio 1:1.41, while maintaining conventional printing for other sizes. This localized application of the direction exchange technique optimizes printing efficiency specifically for the problematic sheet format without affecting the versatility of the system for handling various other sheet sizes and print requirements.
3Object-generated harmful factors
If image direction is exchanged for sheets with aspect ratio 1:1.41, then blank generation is reduced, but print setting complexity increases
Solution Approach 1:
The patent applies self-service by implementing automatic detection of sheet aspect ratio and automatic application of direction exchange when the ratio is 1:1.41. The system autonomously determines whether to exchange directions based on the detected sheet dimensions, eliminating the need for users to manually configure complex print settings. This automated approach reduces perceived complexity while maintaining the benefit of reduced blank generation.

AI summary
Provided is an image forming apparatus including: an acquisition unit that acquires size information regarding a sheet on which an image is to be formed and print data; an image forming unit that forms the image on the sheet on the basis of the print data acquired by the acquisition unit; and a control unit that, if the size information acquired by the acquisition unit indicates a first size of which an aspect ratio of the sheet is 1:substantially 1.41, exchanges vertical and horizontal directions of the image formed on the sheet with respect to the print data by controlling the image forming unit so as to execute a first split print mode of enlarging the image to be printed on two sheets.
