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.

The front panel displays the status of the Ink Cartridge. 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. See page 3-6, When Should You Replace the HP No.80 Supplies?

If you notice a decline in print quality such as lines or dots missing from text / graphics, go to page 6-13, Troubleshooting Print Quality

Problems.

General Information About HP No.80 Supplies

For optimum results from the printer and modular ink delivery system always follow these guidelines when handling the HP No.80 supplies:

n

Always install the ink cartridges, printheads and printhead cleaners before the expire date, which is on the packaging.

n

Install a new printhead cleaner every time you change a printhead.

n

Allow the printer and printhead cleaners to automatically clean the printheads.

n

Install ink cartridges, printheads and printhead cleaners in their color-coded slots.

n n n

Avoid unnecessary removal of the ink cartridges and printheads.

When turning off the printer always use the power Off button on the front panel. The printheads are then stored correctly which prevents them from drying out.

n

Follow the instructions on the front panel of the printer during installation.

The ink cartridges should never be removed while the printer is printing. They should only be removed when the printer is ready for you to replace them. The front panel will guide you through the removal and installation procedure. See page 3-6, When

Should You Replace the HP No.80 Supplies?

CAUTION

Priming the Ink System

When the customer first receives the printer, it is supplied with a set of four setup printheads pre-installed in the printhead carriage.

These setup printheads are used for the priming of the tubes in the modular ink delivery system. The customer must not remove the setup printheads from the carriage without following the procedures in the Setup Guide.

When the Printer is powered ON for the first time, the printer will automatically perform the priming process. Without the priming process, the customer will NOT be able to use the printer.

Why does the Printer require priming: n

The Tubes System is empty when the customer receives the

Printer.

n

The Tubes System has to be pressurized and filled with ink, ejecting any air bubbles.

If the Printing Printheads are installed in the carriage during the priming process, they will be rejected and the front panel will show the "Wrong Model" message.

When Should You Replace the HP No.80 Supplies?

When to change the HP No.80 supplies is mostly determined by you with guidance from the front panel. In conjunction with the messages displayed in the front panel and the message explanations in this chapter, you will be able to choose for yourself when is the right time to change the HP No.80 supplies.

The printer will also display the ink level and will tell you when the ink supply is low, very low or empty. This means you have constantly updated information about the HP No.80 supplies.

Printhead life is anticipated to be 700ml or twelve months in the printer, whichever occurs first, provided that the printhead is used under normal operating conditions (using HP Ink Cartridges only) and its “install before date” has not lapsed. However results vary depending on the print quality setting being used.

NOTE

Carriage Interconnect Wiper

When you order the Carriage Assembly, the Carriage

Interconnect Wiper will come with it. All the instructions needed to use the Carriage Interconnect Wiper will be packaged with the part.

Whenever you replace the printhead, check the empty slots to see if they need cleaning. In extreme circumstances, when a printhead is inserted, it is possible that the printer will not recognize it due to the build-up of ink on the electrical connection between the printhead and the printhead carriage.

Included with the HP DesignJet Printer, is a Carriage Interconnect

Wiper. This tool is provided in a separate package. It also contains replacement sponges and an instruction sheet. This tool should be used for cleaning the electrical interconnects of both the printhead carriage and the printhead.

If the front panel displays the message “Reseat” or possibly

“Failed” next to the offending printhead, try cleaning the flex circuits of the carriage and the Printheads.

NOTE

Do not touch, wipe or attempt to clean the printhead nozzles.

This can damage the printhead and reduce print quality.
