Using the Keyboard
3-10
ON Key
The ON key is used to turn the printer On. The ON key is active
only if the AC power switch (located on the lower right side of
the printer) is in the On (I) position; otherwise it cannot be used.
What Happens When the
ON Key is Pressed?
Once the ON key is pressed, several things occur:
•
the light on the HEAD key flashes
•
the display screen turns On
•
the message <STARTUP> flashes at the top of the display
screen, and the initial software screen (<01 EDIT>)
appears in the display screen.
•
the printer begins its 97-second start-up sequence (refer to
the definition below).
ON Key Summary
=
Light is On:
This indicates that the 97-second printer start-up
sequence is in progress or is completed. The keyboard is active
during the 97-second start-up sequence. The printer is active
only when the start-up sequence is completed.
Light is Off:
This indicates that the printer is Off, and the
keyboard is not active
.
Start-up Sequence:
Definition
The printer start-up sequence is the elapsed time from when the
ON key is pressed to the time the printer is ready for use. The
sequence lasts 97 seconds.
During the printer start-up sequence, the printer system verifies
that everything is operating properly. Hydraulics, pneumatics, and
electronics are enabled, systems checks are performed, printer
faults are monitored, and the ink stream is stabilized.
Once the 97-second start-up sequence is completed, the light on
the HEAD key stops flashing and lights, and the message <HEAD
ON> appears at the top of the display screen. Refer to the HEAD
Key on page 3-14 for further information.
If you press the OFF key while the printer is performing the
start-up sequence, the printer will stop the start-up sequence and
automatically start the four-minute shutdown sequence (which
turns the printer Off).
WARNING: Even though the light on the ON key is Off, AC
power is still applied to the printer unless the AC
power cord or main circuit breaker is
disconnected.
