Dynamic Discharge Unit Selection for Paper Purge in Image Forming Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may forget that a recording material has been discharged during the purge process in image forming systems, and navigating to the discharge destination can be cumbersome, especially when multiple post-processing apparatuses are connected.
Innovation Solution
An image forming system with an abnormality detection unit, position detection unit, selection unit, and purge processing unit that automatically detects conveyance abnormalities, identifies the user's position, selects the nearest discharge unit, and performs the purge process, while also notifying the user of the discharge status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the purge process is performed automatically after conveyance abnormality, then the task of removing recording material is reduced, but users may forget that the recording material has been discharged and may not recognize the discharge destination
Solution Approach 1:
The notification unit provides feedback to the user by notifying them of the discharge destination and status of the purge process. This ensures users are aware that recording material has been discharged and where to retrieve it, preventing forgetfulness while maintaining automatic operation benefits
Solution Approach 2:
The notification unit acts as an intermediary between the automatic purge system and the user, conveying information about the discharge destination and status without requiring direct user interaction with the complex system
2Adaptability or versatility
If multiple post-processing apparatuses are connected to the image forming apparatus, then processing versatility is improved, but the discharge destination becomes remote from the user position and retrieval becomes troublesome
Solution Approach 1:
The system dynamically selects the discharge unit based on the user's position detected by the position detection unit. This allows the system to adapt to different user locations and always direct discharge to the nearest accessible unit, maintaining ease of retrieval even with multiple post-processing apparatuses
Solution Approach 2:
The notification unit informs the user of the selected discharge destination, providing feedback that helps users locate their recording material even when multiple discharge units are available across different apparatuses
3Extent of automation
If a discharge unit is selected in advance for the purge process, then the purge process can be performed automatically, but the discharge destination may not be the nearest to the user position
Solution Approach 1:
The discharge unit selection is dynamic rather than fixed. The selection unit determines the nearest discharge unit based on the user's real-time position detected by the position detection unit, allowing the automatic purge process to simultaneously optimize for user convenience
Solution Approach 2:
The system performs preliminary detection of the user's position before selecting the discharge unit for the purge process. This preliminary action ensures the nearest discharge unit is identified in advance, enabling automatic operation while maintaining proximity to the user

AI summary
Provided is an image forming system including a plurality of discharge units provided for discharging a recording material, an abnormality detection unit which detects conveyance abnormality of a recording material in a conveyance path in the image forming system, a position detection unit which detects a position of a user who performs a task of removing the recording material having caused the conveyance abnormality detected by the abnormality detection unit, a selection unit which selects a discharge unit, which is able to discharge a recording material remaining on a conveyance path of an upstream side and is nearest the position of the user detected by the position detection unit, from the plurality of discharge units, and a purge processing unit which allows the recording material remaining on the conveyance path of the upstream side from the discharge unit selected by the selection unit to be discharged from the discharge unit.
