Compatible Replacement Chip for Canon PGI-5. This is an aftermarket compatible chip for Canon PGI-5 cartridges, which can be installed on any Canon PGI-5 cartridge and will allow your printer to recognize the cartridge as FULL. New chip is required for each cartridge refill.
Why do I need a chip for the Canon PGI-5? Canon has made the PGI-5 cartridges dependent on the chips, basically when you run out of ink on your Canon PGI-5 cartridge, the printer reads a message from the chip that says the cartridge is "empty". This causes the printer to send you error signals until you replace the cartridge. Now you can refill your Canon PGI-5 cartridges and simply add our new compatible chips, which will be recognized by your printer as "new", thereby allowing you to print with your refilled cartridge just as though it were new!
