Printer Preview Display for Paper Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses lack the ability to intuitively confirm which side of a sheet of paper is being printed on, especially when the paper is rotated or inserted incorrectly, leading to potential mistakes in printing orientation and orientation of the paper supply.
Innovation Solution
The apparatus includes a display system that generates and displays preview images showing the paper supply portion and the state of the sheet of paper, allowing users to distinguish between the front and back sides and reflect print settings, ensuring correct orientation and side selection before printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a preview function is provided to display the scanned document before printing, then printing mistakes can be prevented, but it is impossible to confirm for which side of the sheet of paper printing is actually performed
Solution Approach 1:
The patent applies dimensionality change by transitioning from a 2D flat preview display to a 3D立体 display that shows the sheet of paper with printed images in spatial orientation. The display unit presents the printed side and unprinted side of the sheet in a three-dimensional manner, allowing users to visually confirm which side will be printed and the orientation of printing in the vertical direction, thereby resolving the information loss about printing side orientation.
2Adaptability or versatility
If the sheet of paper is rotated by 90 degrees or printing orientation is rotated by 90 degrees, then output can be performed with different orientations, but it becomes more difficult to intuitively recognize a finished state
Solution Approach 1:
The patent uses 3D display to show the sheet of paper and printed images in spatial orientation, making it easy to understand the finished state even when rotated by 90 degrees. The display unit presents the orientation of the printed side and unprinted side in three dimensions, allowing users to intuitively grasp the final output state regardless of rotation angle.
Solution Approach 2:
The patent creates a visual copy of the actual printing outcome on the display unit, showing exactly how the sheet of paper will appear after printing with the selected orientation. This virtual copy allows users to confirm the finished state before actual printing, making it intuitive to recognize the outcome even with rotated orientations.
3Ease of operation
If only front and back of preview image are displayed by flick operation, then front and back can be confirmed, but test printing is still required to confirm arrangement relation of printed images
Solution Approach 1:
The patent performs preliminary action by displaying the arrangement relation of printed images on the printed side and unprinted side in advance on the display unit before actual printing. This preliminary visualization allows users to confirm the spatial arrangement and orientation of printed images without needing to perform test printing, thereby saving time while maintaining ease of operation.
