Image Forming Apparatus Paper Jam Detection via Replenishment Marker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in determining the cause of sheet conveyance failures, such as paper jams, especially during paper replenishment, due to reduced friction coefficients.
Innovation Solution
The system includes an image forming apparatus with detection units to monitor the movement of a support member and detect conveyance failures, and at least one information processing apparatus to analyze data from these detections to determine if the cause of the failure is related to paper replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double feed prevention sheet is used between remaining paper and replenished paper, then sheet conveyance failures are prevented, but the cause of conveyance failures cannot be determined
Solution Approach 1:
A replenishment marker sheet is introduced as an intermediary element between the remaining paper and replenished paper. This marker sheet contains unique identification information that enables traceability of paper batches, allowing the system to determine whether a conveyance failure is caused by replenishment operations while still preventing double feed issues through the presence of the marker sheet itself
2Productivity
If paper replenishment is performed frequently to maintain continuous operation, then productivity is improved, but sheet conveyance failures increase due to reduced friction coefficient
Solution Approach 1:
The system implements feedback by detecting the replenishment marker sheet during paper feeding operations. When the marker sheet is detected, the control unit identifies that replenishment has occurred and can take appropriate measures or notify users, creating a closed-loop system that monitors and responds to replenishment events to prevent conveyance failures
