Method of identifying printing cartridge characteristics with capacitive sensors
First Claim
1. A method of determining a characteristic of a printing cartridge, the method comprising the step of actuating a number of capacitive sensors within an array of such sensors with an actuating formation positioned on the printing cartridge, the actuating formation representing data relating to a characteristic of the cartridge, so that the capacitive sensors, when actuated, generate a signal carrying data relating to that characteristic.
