Decoloring Toner Print Control Through User Usage Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems fail to effectively promote the use of decoloring toner printing among users who seldom use it, leading to inefficient resource utilization and recycling of printed sheets.
Innovation Solution
An image processing apparatus that counts user-specific usage of decoloring and normal toner, providing notifications to users with low decoloring toner usage ratios to encourage decoloring toner printing, and optionally recommending the use of reuse sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system separately counts decoloring toner and normal toner usage, then consumable management and process adjustment are improved, but user awareness and promotion of decoloring toner usage are insufficient
Solution Approach 1:
The system provides feedback to users about their decoloring toner usage ratios through notifications. The notification unit compares each user's decoloring toner usage ratio against a reference value and notifies users whose ratio is below the reference, creating a feedback loop that encourages increased decoloring toner usage to improve recycling rates.
2Productivity
If notifications are provided to users with low decoloring toner usage, then user awareness is improved, but system complexity increases
Solution Approach 1:
The notification system applies local quality by providing targeted notifications only to specific users whose decoloring toner usage ratio falls below the reference value, rather than notifying all users uniformly. This selective approach optimizes resource usage and reduces unnecessary notifications while effectively promoting decoloring toner usage among relevant users.
3Productivity
If user-specific counting is implemented, then resource recycling efficiency is improved, but data processing requirements increase
Solution Approach 1:
The system extracts only the essential data elements needed for decoloring toner promotion - specifically, the decoloring toner usage ratio for each user - rather than storing and processing all possible printing data. This extraction approach enables effective user-specific notifications and recycling promotion while minimizing data storage and processing requirements.

AI summary
An image processing apparatus that is capable of performing image formation on recording sheets, by switchingly using decoloring toner and normal toner. The number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner are counted with respect to the recording sheets on a user-by-user basis. A use ratio of a logged-in user who has logged in the image processing apparatus is acquired, which indicates a ratio of the number of sheets printed with the decoloring toner to a total number of the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner based on the count. In a case where the use ratio is equal to or lower than a first threshold value, a notification for recommending printing using the decoloring toner is provided to the logged-in user.
