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.
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.
