How to Reset the Chip on an HP 88XL Inkjet Cartridge

An HP 88XL inkjet printer contains internal memory that stores information about ink level from the previous two ink cartridges. If a printer indicates a low ink level warning, a user can refill the cartridge with ink, which is cheaper than buying a new cartridge. However, the printer may indicate a low ink level warning even after refilling the cartridge. This warning can be removed by resetting the inkjet cartridge chip.
