The ink system in the 1055CM printer includes three components: a printhead, printhead cleaner, and an ink cartridge to provide large-capacity ink, unattended printing, ease of use, reliability, and low cost. The ink system offers true 600 dpi and advanced dithering algorithms for exceptional image quality prints.
Each 600 dpi thermal Inkjet printhead applies ink droplets onto paper and has a reservoir that holds enough ink for several prints. The printer automatically refills the printhead from the ink cartridge whenever the ink volume in the printhead reservoir becomes low. The printer uses the printhead cleaners to clean and maintain the printheads, to ensure best possible image quality, and to seal the printheads when they are not in use to ensure long life.

HP80 Ink supplies

The ink system components (the printhead, printhead cleaner, and ink cartridge) are called the HP80 Ink Supplies, and they are coded with an HP80 icon to help to reorder the correct replacement components.
Each color ink cartridge (cyan, magenta, yellow, and black) can be purchased separately from an HP retailer and should be purchased when an existing ink cartridge is low on ink, if you intend to print continuously.
The printhead and printhead cleaner are supplied as a single unit and should always be installed as a matched pair. They do not require replacement every time a new ink cartridge is installed in the printer. It is only necessary to replace the printhead/printhead cleaner when the existing components are time expired.
Part numbers for the HP80 Ink Supplies are listed in the table below.

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
  1. This device may not cause harmful interference.
  2. This device must accept any interference received, including interference that may cause undesired operation.
Pursuant to Part 15.21 of the FCC Rules, any changes or modifications to this equipment not expressly approved by the Hewlett-Packard Company, may cause harmful interference and void the FCC authorization to operate this equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interferences by one or more of the following measures:
  • Reorient the receiving antenna.
  • Increase the separation between the equipment and the receiver.
  • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
  • Consult the dealer or an experienced radio/TV technician for help.
