Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems inaccurately count prints on rolled sheets due to variable image stop positions, leading to incorrect charging of printing fees.
Innovation Solution
An image forming system with a hardware processor that adjusts the print counting position on the conveyance path between the image forming and winding sections, allowing precise determination of the image stop position for accurate print counting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed print counting position is used between the image forming section and winding section, then the device structure is simple, but the print count becomes inaccurate when the image stop position changes
Solution Approach 1:
The patent applies the dynamics principle by making the print counting position adjustable rather than fixed. The hardware processor can change the print counting position on the conveyance path according to different image stop positions, allowing the system to adapt dynamically to varying printing requirements while maintaining accurate print counting.
Solution Approach 2:
The patent implements parameter changes by modifying the position parameter of the print counting location. The system changes the print counting position parameter based on the image stop position, enabling accurate print counting across different operating conditions without requiring complex mechanical adjustments.
2Adaptability or versatility
If the image stop position is changed to accommodate different print jobs, then the system is more versatile, but the print count accuracy deteriorates
Solution Approach 1:
The system dynamically adjusts the print counting position in response to different image stop positions. This dynamic adaptation allows the system to maintain accurate print counting regardless of whether the image stops at position A, B, or C, thereby preserving measurement precision while supporting versatility.
Solution Approach 2:
The system uses feedback from the image stop position to determine the appropriate print counting position. By monitoring where the image stops and adjusting the counting position accordingly, the system ensures accurate print counting is maintained across all versatile operating modes.
3Ease of operation
If print counting is based on a predetermined position on the conveyance path, then the counting mechanism is simple, but the fee calculation becomes incorrect when image stop position varies
Solution Approach 1:
The system changes the print counting position parameter based on the image stop position to ensure accurate fee calculation. This parameter adjustment approach maintains ease of operation by using software-based control rather than complex mechanical systems, while achieving correct fee calculation across different printing scenarios.

AI summary
An image forming system includes: a sheet conveyance section configured to convey a rolled sheet; an image forming section configured to form an image on the rolled sheet; a winding section configured to wind the rolled sheet; and a hardware processor. The hardware processor is capable of changing a print counting position on a conveyance path between the image forming section and the winding section, the print counting position at which a print is counted based on the image formed on the rolled sheet.
