When you refill HP color ink cartridges, you also need to reset the cartridge. Each HP color cartridge contains a chip that communicates with the printer. When the ink in the cartridge becomes low, the chip signals the printer to display a low ink warning. This warning will still be displayed after you refill the cartridge. Resetting the chip takes about two minutes. This manual reset, when combined with refilling used cartridges, can save you money as well as the aggravation of having your printer constantly warning you of low ink levels.
