Automated Post Processing Position Control via Image Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post processing apparatuses require manual adjustment of post processing positions based on visual confirmation, leading to time-consuming and labor-intensive processes, with potential waste of toner and paper due to unnecessary marks for positioning adjustments.
Innovation Solution
A post processing apparatus equipped with a reader to detect the position of the paper edge and image, using this information to control post processing positions without printing unnecessary marks, thereby automating the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of post processing positions is performed based on visual confirmation, then the post processing position can be adjusted, but it becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the manual visual confirmation method with an automated image processing system. The reader captures an image of the paper, and the control unit automatically detects the printed image position and calculates the post processing position, eliminating the need for manual visual measurement and adjustment.
Solution Approach 2:
The system performs self-adjustment by automatically detecting the printed image position and calculating the appropriate post processing position without requiring operator intervention. The control unit autonomously determines the position based on image analysis, making the system self-sufficient in positioning tasks.
2Measurement precision
If marks are printed on paper for positioning adjustment, then the post processing position can be controlled, but unnecessary marks remain as images
Solution Approach 1:
The patent replaces the mark-based positioning method with direct image analysis. Instead of printing marks and using them as reference points, the system directly analyzes the printed image content to determine positioning, eliminating the need for additional marks on the paper.
Solution Approach 2:
The patent extracts only the necessary information (printed image position) from the paper image without adding unnecessary elements. The system processes the existing printed image to determine positioning, removing the need to print additional marks that would remain as unwanted artifacts.
3Manufacturing precision
If sample output is performed for adjustment, then the post processing position can be optimized, but waste of toner and paper occurs
Solution Approach 1:
The system performs preliminary image analysis on the first sheet to determine the printed image position and calculate the optimal post processing position. This preliminary action enables accurate positioning for all subsequent sheets without requiring additional sample outputs, preventing waste of toner and paper.
Solution Approach 2:
The system uses feedback from image analysis of the first sheet to automatically adjust and determine the post processing position for all sheets. The control unit learns the positioning requirements from the initial image analysis and applies this information to optimize processing for the entire batch, eliminating the need for repeated sample outputs.

AI summary
A post processing apparatus includes: a reader that reads paper on which an image is formed by an image forming apparatus to acquire a read image; a post processor that performs post processing on the paper; and a hardware processor that detects a position of an edge of the paper and a position of the image from the read image acquired by the reader, and controls a post processing position in the post processor on the basis of the position of the edge of the paper and the position of the image detected.
