Priming the Ink System 83
Ink Supplies
• Do not drop the Printheads.
• Proper handling will assure optimum performance throughout the Printhead life.
• The Maintenance Cartridge should always be handled and stored upright to avoid a potential
spillage of ink.
• Do not touch the end of the Ink Cartridge which is inserted into the printer as there may be a small
amount of ink on the connection.
• Avoid storing partially used Ink Cartridges on their ends.
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 Carriage Assembly. 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:
• The Tubes System is empty when the customer receives the Printer.
• The Tubes System has to be pressurized and filled with ink, ejecting any air bubbles.
When Should You Replace the Ink Supplies?
When to change the ink 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 ink supplies.
The Printer will also display the ink level and will tell you when the ink supply is low on ink. This means
you have constantly updated information about the ink supplies.
Printhead life is anticipated to be 1000ml 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.
Obtaining Ink Cartridge Information
Use the following procedure to obtain Ink Cartridge information:
CAUTION: If the Printing Printheads are installed in the carriage during the priming process,
they will be rejected and the front panel will show a warning message.
