Image Formation Condition Regulation Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses often suspend print processing for image creation condition regulation, leading to potential disruptions and suboptimal image quality, especially when corrections are initiated too early in consecutive print jobs.
Innovation Solution
An image forming apparatus that includes an image formation control section, a counter, an image creation condition regulation section, and a regulation control section, which activates the regulation of image creation conditions only after a predetermined cumulative printed-paper number or operation time is reached, thereby minimizing interruptions during print processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image creation condition regulation is executed during consecutive print processing, then image quality is maintained, but print processing is suspended
Solution Approach 1:
The system performs image creation condition regulation in advance, before consecutive print processing begins. By regulating conditions preliminarily and storing regulation results, the system avoids suspending print processing during actual printing while maintaining image quality through pre-applied correction values.
Solution Approach 2:
The system dynamically determines whether to execute regulation based on the printing state. When consecutive print processing is detected, regulation is suppressed; when printing is not consecutive or conditions warrant it, regulation is performed. This dynamic control balances image quality maintenance with print processing continuity.
2Manufacturing precision
If correction timing is set early in consecutive print processing, then image quality issues are addressed, but print processing efficiency decreases
Solution Approach 1:
The system sets correction timing preliminarily but conditionally. Correction values are calculated in advance and stored, but actual regulation execution is deferred until appropriate timing outside consecutive print processing. This preliminary preparation without immediate execution eliminates time loss while ensuring image quality correction is applied.
Solution Approach 2:
The system skips regulation execution during consecutive print processing by utilizing pre-calculated correction values. Instead of performing regulation during printing (which would cause suspension), the system rushes through the printing process using stored correction data, thereby maintaining efficiency while still addressing image quality issues.
3Manufacturing precision
If regulation is performed frequently, then image quality is maintained, but print processing interruptions increase
Solution Approach 1:
The system dynamically adjusts regulation frequency based on printing conditions. During consecutive print processing, regulation is suppressed regardless of cumulative counts. Regulation is only performed when printing is not consecutive or when specific conditions are met, creating a dynamic adaptation that maintains image quality while ensuring smooth print processing without interruptions.
Solution Approach 2:
The system maintains continuity of print processing by performing regulation outside consecutive printing operations. Correction values are prepared in advance and applied without interrupting the printing flow, ensuring that the useful action of print processing continues uninterrupted while image quality regulation is still achieved through non-intrusive timing.

AI summary
An image forming apparatus includes an image forming unit, image formation control section, counter, image formation condition regulation section, controlled printed-paper number storage section, and regulation control section. The image forming unit includes a plurality of functional sections. The counter counts a cumulative printed-paper number in a series of image formation processing. The image formation condition regulation section regulates an image formation condition of at least one of the functional sections. The controlled printed-paper number storage section stores a benchmark printed-paper number and first allowable value to determine the timing of regulating the image creation condition. The first allowable value is set to be less than the benchmark printed-paper number. The regulation control section activates the image creation condition regulation section after the series of image formation processing when the cumulative printed-paper number is equal to or greater than the first allowable value after the series of image formation processing.
