The Everprint CHIP-CAN-EXV49-C is a cyan cartridge chip listed for Canon IR C3330 and the C-EXV49-C cartridge reference. It is intended to help the device identify the cartridge and read its recorded status.
The chip stores information such as page count and toner use. Its cyan colour designation distinguishes it from other colour variants in the C-EXV49 range. The product name carries a 19K yield designation.
The listing describes replacing the chip as a way to use a refilled cartridge again. This is a cartridge component for that refill and reuse purpose.
