Every year it appears that the Inkjet Cartridge manufactuers are spearheading a never ending battle to try and prevent you the user from re-using the products you have purchased.
This is an overview of the procedure from Cartridge World detailing the operation of Epsons T068/T069/T078 series cartridges.
2nd Internal Monitoring System disables re-use of Cartridge
When an individual cartridge is near the “Low Ink” (about 75 percent empty) stage, the monitoring system renders the cartridge “Un-Usable” and non refillable.
When the cartridge is in the “Low Ink” stage it will not be refillable.
In the event the ink level indicator drops to 25%,the cartridge will become electronically damaged and not recyclable.
A second backup ink monitoring system is an ink sensor inside the cartridge near the
egress hole. When this sensor gets dry due to ink depletion, the chip is written to as empty, and the cartridge is no longer resettable.
Refilling impossible if cartridge is empty
The result of all this is that if the chip receives a low or empty ink message it is not
resettable.
For these cartridges, like a car gas tank , they should always be refilled before they are empty.
