Toner Near Empty Detection and Control via Network Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming devices often indicate a toner cartridge as near empty unnecessarily, leading to premature replacement and wastage, while users may not receive timely notifications for replacement, resulting in interrupted printing due to lack of toner.
Innovation Solution
An image forming device with a toner level detecting system that communicates with a controlling device to determine whether to indicate a toner near empty state, allowing for controlled toner cartridge replacement and optimizing usage based on user contracts and stock availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the toner level detecting device detects the toner near empty state and indicates it on the indicating device, then the user can prepare for toner cartridge replacement in time, but the user may replace the toner cartridge prematurely when toner is still remaining, leading to wastage
Solution Approach 1:
The system implements feedback by continuously monitoring toner levels through the toner level detecting device and communicating with the controlling device. The controlling device receives toner level information and determines whether to issue replacement notifications based on actual usage patterns and contract terms, creating a closed-loop feedback system that prevents both premature and delayed replacement
Solution Approach 2:
The invention changes the parameter for determining replacement timing from a fixed toner level threshold to a dynamic determination based on multiple factors including usage patterns, contract terms, and stock availability. The controlling device adjusts the replacement notification timing by analyzing these varying parameters rather than using a static threshold
2Loss of substance
If the toner near empty indication is not indicated on the indicating device, then toner wastage is reduced, but the toner cartridge is emptied before the user knows, resulting in interrupted image formation
Solution Approach 1:
The system performs preliminary action by notifying the user of the toner near empty state in advance, allowing time to prepare for replacement. The notification is issued before the toner is completely depleted, giving the user opportunity to order or retrieve a replacement cartridge while maintaining continuous operation capability
3Productivity
If the toner cartridge replacement is provided rapidly through the controlling device, then the necessity of switching detection timing is eliminated, but the system complexity increases due to communication infrastructure requirements
Solution Approach 1:
The controlling device serves as an intermediary between multiple image forming devices and the user. It centralizes the communication function, receiving toner level data from devices and sending replacement notifications, thereby simplifying the overall system architecture while enabling rapid coordinated replacement across multiple devices

AI summary
A controlling system comprising an image forming device and a controlling device for the image forming device, the image forming device having an indicating device which can indicate that a toner cartridge is in a toner near empty state and a communication part for communicating with the controlling device via a communication network, and when the toner near empty state of the toner cartridge is detected, the communication part transmits the information to the controlling device. The controlling device has a controlling condition table in which a controlling condition set for each image forming device to be controlled is recorded, and when a toner near empty signal is received from the image forming device to be controlled, the controlling device refers to the controlling condition of the image forming device recorded in the table, and outputs or does not output a toner near empty indication instruction signal depending on the controlling condition. When the image forming device receives the toner near empty indication instruction signal, it displays so on the indicating device.
