Workflow Overview 1-17
Daily Shutdown Not
Recommended
DO NOT POWER DOWN THE PRINTER. Power is required to
maintain vacuum to the printheads, which keeps ink from seep-
ing out. If power is unexpectedly removed from the printer, print-
head vacuum will be lost and ink will leak from the printheads.
The amount of ink lost will be limited to the ink currently in the
printheads, not the ink in the ink supply boxes which has not yet
been pumped to the printheads.
Since automatic head maintenance cannot occur when the
printer is powered down, keep the printer powered on at all times
if possible. If automatic head maintenance does not occur for an
extended period, manual purging may be necessary to restore
the printheads to working condition.
See page A-4 for information on using the included auxiliary
power supply for the vacuum/pressure system.
The printer will automatically enter a Sleep mode when it has
been idle for a user-defined period of time (see page 3-5 for
details).
