Print Cartridge Memory Update for High Yield Toner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print cartridges do not accurately reflect their high yield capacity, leading to premature replacement and inefficiency in networked printing systems, as the original memory values do not account for increased toner or ink capacity, and there is a need for accurate prediction of end-of-life to reduce waste and costs.
Innovation Solution
A method and system that refills toner cartridges with a replacement chip and toner having enhanced coverage efficiency, allowing the hopper to hold more toner than the waste bin, and includes a memory update to reflect the new page yield, enabling accurate monitoring and management by managed print service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the initial value in the memory device is updated to reflect increased print capacity, then the cartridge can be used until almost empty reducing waste, but the status page may not accurately reflect the actual toner levels
Solution Approach 1:
The system implements feedback by continuously monitoring actual toner levels through sensors and comparing them against the calculated remaining life based on initial values. This allows the system to adjust status information dynamically, ensuring accurate representation of actual toner levels while maximizing cartridge utilization.
2Productivity
If remanufactured cartridges are used to reduce costs and environmental impact, then operational efficiency improves, but accurate prediction of end-of-life becomes more difficult
Solution Approach 1:
The system enables self-service by having the memory device automatically track and update its own remaining life based on actual usage patterns and toner consumption rates. This self-monitoring capability allows remanufactured cartridges to accurately predict their own end-of-life without requiring external intervention or complex manual tracking.
Solution Approach 2:
The patent replaces mechanical estimation methods with electronic monitoring systems. Sensors and processors automatically detect toner levels and calculate remaining capacity, substituting physical measurement and manual tracking with automated electronic systems that provide more accurate and reliable end-of-life predictions.
3Productivity
If high yield cartridges are used to reduce replacement frequency, then productivity increases, but the printer may prevent the cartridge from realizing its full print life due to incorrect initial values
Solution Approach 1:
The system dynamically changes the initial value parameter in the memory device to reflect the actual high-yield capacity of the cartridge. By adjusting this parameter based on the specific cartridge configuration and toner load, the printer accurately recognizes the extended print life and allows the cartridge to be utilized fully without premature replacement warnings.

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.
