Refilled Toner Cartridge Yield via Replacement Chip Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print cartridges do not accurately reflect increased capacity after refilling, leading to premature prevention of printing and incorrect status page information, as the initial memory values are not updated to match the enhanced capacity.
Innovation Solution
Refill the toner cartridge with a new amount of toner that exceeds the original capacity, using a replacement cartridge chip with updated memory to indicate the new toner amount, ensuring the cartridge can print until almost empty while maintaining accurate status page information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the toner cartridge is refilled with more toner than the original capacity, then the print life is extended, but the memory information does not reflect the increased capacity causing premature printing prevention
Solution Approach 1:
The patent changes the parameter stored in the memory from the original toner capacity value to a new value that reflects the increased toner capacity after refilling. This parameter change allows the printer to accurately recognize the extended print life and prevents premature printing prevention, resolving the contradiction between extended print life and accurate memory information.
2Device complexity
If the initial memory value is not updated after refilling, then the cartridge structure remains simple, but the status page displays incorrect information and printing is prevented prematurely
Solution Approach 1:
The patent performs preliminary action by updating the memory information with the new toner capacity value before the cartridge is returned to service. This preliminary update ensures that when the printer reads the memory, it receives accurate information about the increased capacity, displaying correct status page information and preventing premature printing prevention without requiring complex structural changes.

AI summary
Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of a print yield. Disclosed is a method and system for allowing the memory to have data indicative of an increased print yield.
