HP No.80 Ink Supplies Troubleshooting

What are HP No.80 Supplies?

For each of the four ink colors used in the printer, there are three separate components. The printhead and the printhead cleaner are supplied together, and the ink cartridge is supplied separately. All of these components are called the HP No.80 Supplies. They are coded with an HP No.80 selection number to identify the correct replacement supplies.

Ink Cartridges

The HP No.80 ink cartridges for the HP DesignJet 1050C and 1055CM printers require no maintenance or cleaning. As long as each ink cartridge is inserted correctly into its slot, the ink will flow to the printheads.

Printheads and Printhead Cleaners

The HP No.80 printheads are extremely durable and do not need to be replaced every time an ink cartridge is replaced. They are independent of the ink cartridges and will continue giving excellent image quality results even if the ink cartridges are low on ink. See page 3-6, When Should You Replace the HP No.80 Supplies?
