Specifications:

HP # 10, 11,14, 80, 81, 82, 83, 84, 85, 88 cartridges all have small chips on the side of the cartrigdes which prevent them from being recognised in the printer once they have been refilled. Unfortunately the original HP chips are not resetable, but we now
have a solution to this - a resettable chip. Each resettable chip is unique to the specific colour cartridge. Once you have the resettable chips you
can use our HP Chip Resetter which can reset the chips back to full status unlimited times.
