Image Defect Re-formation Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming technologies lack an efficient method for re-forming defective images on a second conveyance medium at a selected timing, which can disrupt the printing process and increase operational complexity.
Innovation Solution
An image forming apparatus equipped with processing circuitry that receives timing selections for re-forming defective images based on information from a first conveyance medium, allowing for precise re-formation on a second medium, including the use of slip sheets for defect detection and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If defective images are re-formed immediately upon detection, then image quality is improved, but printing process disruption increases
Solution Approach 1:
The system performs preliminary defect detection during the printing process, identifies defective images before completion, and prepares re-formation in advance by storing original image data and selecting appropriate re-formation timing, thus resolving the conflict between immediate correction and process continuity
Solution Approach 2:
The system dynamically adjusts the re-formation timing based on the selected mode (immediate re-formation, delayed re-formation, or batch re-formation), allowing flexible adaptation between image quality requirements and printing process continuity needs
2Manufacturing precision
If re-formation is performed at every defect detection, then image quality is improved, but operational complexity increases
Solution Approach 1:
The system automatically manages the re-formation process by detecting defects, storing original image data, selecting re-formation timing based on user preferences, and executing re-formation without requiring manual intervention, thus improving image quality while maintaining ease of operation
Solution Approach 2:
The system changes the re-formation timing parameter based on user-selected modes (immediate, delayed, or batch), allowing the same defect detection and re-formation mechanism to adapt to different operational requirements without increasing complexity

AI summary
An image forming apparatus includes processing circuitry. The processing circuitry receives a timing selected for re-forming an image and re-forms the image determined to be defective based on information about the image formed on a first conveyance medium, on a second conveyance medium at the selected timing.
