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. 80 80 Expanding Possibilities Pojfdjop ernk aure 80 Ironk Pojfdjop ernk Pojfdjop ernk aure Chorme Printhead and Printhead Cleaner Expanding Possibilities 80 kheuhg kheuhg sfrfefg sfrfefg 80 IInnkkercovarCtraipdsge Ink Cartridge Ink Cartridges The HP No.80 ink cartridges for the HP DesignJet 1050C and 1055CM printers require no maintenance or cleaning.

With the front panel, detailed information can be checked on the Ink Cartridges. 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.
