Image Forming Device Double-Side Calibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming devices struggle to maintain equivalent image quality on both sides of printing paper during double-side printing, as calibration is typically performed between pages or jobs, leading to inconsistent quality.
Innovation Solution
An image forming device with a calibration unit, judging units to determine when to perform calibration, and a control unit to ensure calibration is applied only before printing the first side in double-side printing, maintaining consistent settings for both sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If calibration is performed at the moment between pages to be printed, then image quality can be improved in a timely fashion, but image quality becomes inconsistent between first and second sides in double-side printing
Solution Approach 1:
The patent applies preliminary action by performing calibration only before printing the first side of double-side printing, establishing consistent baseline settings that will be maintained for subsequent printing operations including the second side, thus ensuring quality consistency while still enabling timely calibration when needed
2Manufacturing precision
If calibration is performed before each page, then image quality is maximized, but printing productivity decreases due to frequent calibration interruptions
Solution Approach 1:
The patent implements periodic action by performing calibration at specific intervals and conditions (between pages or at job boundaries, and only before first sides in double-side printing) rather than continuously before every page, thus maintaining image quality while minimizing interruptions to printing productivity

AI summary
An image forming device, which is capable of double-side printing to form an image on each of first and second sides of a recording medium, includes a calibration unit configured to perform calibration for modifying quality of the image to be formed, a first judging unit configured to judge, for each page to be printed, whether the calibration is to be performed, a second judging unit configured to judge whether a page to be printed is one of a first side in one-side printing and a first side in the double-side printing, and a control unit configured to control the calibration unit to perform the calibration when the first judging unit judges that the calibration is to be performed, and the second judging unit judges that the page to be printed is one of the first side in the one-side printing and the first side in the double-side printing.
