HP No.80 Ink Supplies Troubleshooting
| Priming the Ink System |
| When the customer first receives the printer, it is supplied with a set |
| of four setup printheads |
| 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 |
CAUTION | |
| priming process, they will be rejected and the front panel will |
| show the "Wrong Model" message. |

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.
