Image Processing System Media Usage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional management systems for eco-print systems face challenges in controlling the quantity of printing media used, leading to excessive capacity in storing trays and waste due to inadequate reuse of decolorized media.
Innovation Solution
An image processing system that includes a receiving unit and a controller to manage the distribution and usage of media by calculating thresholds for media usage, limiting the quantity of new media used, and promoting the reuse of decolorized media through a network of MFP devices, decolorizing devices, and server management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a larger quantity of media is distributed in response to the use of new media, then the availability of media for printing is improved, but the capacity of storing trays is exceeded and a place to store decolorized media is required separately
Solution Approach 1:
The system performs preliminary actions by notifying users in advance when the number of used media approaches the threshold, and by pre-preparing decolorized media in the storing tray before it is needed. This allows smooth transition to decolorized media without exceeding tray capacity or interrupting printing operations.
Solution Approach 2:
The management server continuously monitors the number of used media and provides feedback to both the user (via notifications) and the system (by controlling media distribution). This feedback mechanism enables dynamic adjustment of media usage to prevent tray capacity overload while ensuring sufficient media availability.
2Ease of operation
If decolorized media are not reused, then the simplicity of operation is maintained, but material waste increases
Solution Approach 1:
The system enables self-service by automatically managing the decolorization and reuse process. The management server controls the distribution of decolorized media without requiring manual user intervention, making the waste-reduction process as simple as conventional media replacement while significantly reducing material waste.
Solution Approach 2:
Instead of discarding used media, the system recovers it through decolorization and makes it available for reuse. The decolorizing device restores the media by removing the printed content, and the management server ensures these recovered media are properly tracked and redistributed, transforming waste into reusable resources.
3Device complexity
If the number of used media is not monitored, then the device complexity is reduced, but the control over media usage is insufficient
Solution Approach 1:
The management server acts as an intermediary that centralizes the monitoring and control functions. Instead of adding complex monitoring hardware to each printing device, the server handles media tracking, threshold management, and coordination with the decolorizing device, simplifying individual device complexity while maintaining comprehensive usage control.
Data Source
AI summary
A system includes a receiving unit and a controller. The receiving unit receives data about the number of processes performed in an image forming unit to form an image with a decolorable color material and data about the number of processes performed in a decolorizing unit to decolorize an image formed with the decolorable color material. Based on the data received by the receiving unit the controller calculates the number of media in user's use in a condition after they are subjected to image formation by the image forming unit and before they are decolorized by the decolorizing unit. The controller deters image formation by the image forming unit if the number of the media in user's use exceeds a first threshold, and allows the image forming unit to form an image if the number of the media in user's use does not exceed the first threshold.
