The HP 81 Light Cyan DesignJet Dye Printhead and Printhead Cleaner (C4954A) supplies light cyan dye ink for compatible DesignJet printing systems. It combines the printhead with a cleaner in one product, so both components are included together.
The printhead uses HP Thermal Inkjet technology and has 512 nozzles across a 0.85-inch swath. HP lists the ink volume as 13 ml. These details describe its light cyan printing function and printhead configuration.
In the box: one printhead and one printhead cleaner.
