The following illustration will help you identify the components of the HP No. 81 and 83 supplies and where they are installed in the printer.

The selection number HP No. 81 or HP No. 83 on the ink cartridges, printheads and printhead cleaners makes it easy for you to find the correct HP printing supplies for your printer. Determine the color of the printhead or ink cartridge you need, then make sure you purchase or order an HP No. 81 or HP No. 83 printhead with printhead cleaner or ink cartridge. Each ink cartridge and printhead with printhead cleaner can be purchased separately from your usual HP retailer. See ordering ink supplies.
