Print Control Apparatus Secondary Transfer Voltage Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print control systems for production printing require significant user effort and time to adjust secondary transfer voltage settings, with conventional methods often necessitating multiple operations and visual checks, leading to poor operability and potential suboptimal settings.
Innovation Solution
A print control apparatus that communicates with an image forming apparatus to print charts, read adjustment values, and display prompts for adjusting the secondary transfer voltage, improving operability by automating the adjustment process and reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the secondary transfer voltage is adjusted manually by visual checking of patch images, then the user can determine optimal settings, but the user's workload and time consumption increase significantly
Solution Approach 1:
The patent replaces the manual visual checking process with an automated density sensor-based detection system. The density sensor objectively measures patch image density values, substituting the subjective human visual assessment mechanism. This automation eliminates the time-consuming iterative process of manually adjusting and visually checking multiple patch images while maintaining accurate determination of optimal secondary transfer voltage settings.
2Extent of automation
If multiple operations are required to display adjustment value information and setting screens, then complete control is achieved, but the operability deteriorates
Solution Approach 1:
The patent merges the display of adjustment value information and the setting screen into a single integrated interface. The display unit simultaneously shows the current adjustment value, the prompt message indicating whether readjustment is needed, and the setting screen for manual adjustment all in one view. This eliminates the need for multiple separate operations to navigate between different screens or views, significantly improving readjustment operability while maintaining complete control over the adjustment process.
3Productivity
If the density sensor is used to automatically set secondary transfer voltage, then visual checking is eliminated, but the optimal voltage that users desire may not be set
Solution Approach 1:
The patent implements a feedback mechanism where the density sensor automatically measures patch image density and determines the secondary transfer voltage setting, then provides this information to the user through the display unit. The system includes a prompt message that informs users whether readjustment is needed based on the automatic measurement results. This feedback loop allows users to review the automatic settings and perform manual readjustment if desired, ensuring user satisfaction while maintaining high adjustment efficiency through the automated measurement and information provision process.

AI summary
A print control apparatus that improves operability in readjusting a secondary transfer voltage that has been adjusted. The print control apparatus that communicates with an image forming apparatus. The print control apparatus includes an instruction unit that instructs the image forming apparatus to execute a process that prints a predetermined chart, reads the predetermined chart by the reading device, and sets a secondary transfer voltage, a reception unit that receives an adjustment value obtained by the process from the image forming apparatus, and a display control unit that controls a display unit to display an object that prompts a user to adjust at least the secondary transfer voltage based on reception of the adjustment value obtained by the process by the reception unit.
