Toner Container Authenticity Detection and Consumption Ratio Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses do not effectively differentiate between genuine and non-genuine toner containers, leading to inaccurate consumption and waste toner amount calculations, which can result in inefficient usage and increased costs for users.
Innovation Solution
The apparatus includes a determining section that identifies whether a toner container is genuine or non-genuine using IC tags, and calculates and displays the consumption ratio of toner between genuine and non-genuine containers, allowing users to make informed decisions about replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus stops displaying remaining toner amount when a non-genuine toner container is detected, then it prevents inaccurate consumption calculations, but it reduces information availability and user convenience
Solution Approach 1:
The display information is segmented into two distinct modes: when a genuine toner container is detected, the remaining toner amount is displayed; when a non-genuine container is detected, the consumption ratio is displayed instead. This segmentation allows the system to provide appropriate information based on the container type, resolving the contradiction between measurement precision and information availability.
Solution Approach 2:
The display parameter changes dynamically based on the authenticity of the toner container. The system switches between displaying remaining toner amount (for genuine containers) and consumption ratio (for non-genuine containers). This parameter change allows the system to maintain measurement precision for genuine containers while still providing useful information for non-genuine containers.
2Reliability
If the apparatus provides no information when a non-genuine toner container is detected, then it ensures accurate data integrity, but it reduces user awareness and informed decision-making
Solution Approach 1:
The system provides feedback to the user about the toner container status by displaying the consumption ratio when a non-genuine container is detected. This feedback mechanism maintains data integrity by not displaying inaccurate remaining amount information, while still keeping the user informed about toner consumption patterns, enabling informed decision-making regarding container replacement.
3Productivity
If the apparatus calculates consumption based on assumptions for non-genuine containers, then it maintains continuous operation, but it reduces calculation accuracy
Solution Approach 1:
The system treats non-genuine toner containers as disposable alternatives with different consumption characteristics. Instead of attempting to maintain the same calculation accuracy as genuine containers, it displays a consumption ratio that reflects the actual performance of these alternative containers, allowing continuous operation with appropriate information adjustment.

AI summary
An image forming apparatus includes a toner supply section, an image forming section, a touch panel, a determining section, a calculating section, and a display section. The determining section determines whether a toner container mounted to the toner supply section is a first container or a second container which differs from the first container. The calculating section calculates a consumption amount of toner consumed for the image forming section to form an image on paper when the determining section determines that the toner container is the second container. The display section displays a ratio of a second consumption amount to a first consumption amount on the touch panel. The first consumption amount is a consumption amount of the toner when the toner container is the first container. The second consumption amount is a consumption amount of the toner when the toner container is the second container.
