Function
The three vacuum zone control handles determine which of
the three print zones on the printer table will have vacuum
applied when the vacuum pump is switched on. The vacuum
zones are opened or closed by the handles.
A vacuum foot pedal switch is provided to facilitate the process
of securing the media on the vacuum table. The foot pedal
toggles the table vacuum on/off. The vacuum must be turned
on prior to starting a print.
A bleed valve can be adjusted to reduce or increase the amount
of vacuum suction on the media. Less vacuum reduces artifacts
caused by suction when imaging on flexible media.
The print button is located at the corner where media is
loaded on the table. After positioning the media and activating
the vacuum, press the button to start the print.
The green colored beacon light is mounted on the top surface
of the carriage. The purpose of the light is to indicate basic
machine status to the operator. See the table after this section
for the significance of the different states of the light.
If a situation requires an immediate shutdown of all printer
activity, press one of the three Emergency Stop buttons. To
recover from an emergency shutdown, resolve the problem
that prompted the shutdown and then release the Emergency
Stop by twisting it slightly clockwise. Restoring functionality
to all disabled systems can only occur through an operator
command at the Control Station. See below for the parts of
the hardware interface affected by an Emergency Stop.
Daily printhead maintenance consists of an ink purge and
suction cleaning of the printheads. The maintenance station
cover is slid open to access the printheads and the suction
nozzle. The maintenance station is located under the carriage.
Maintenance is performed when the carriage is parked at the
end of the gantry.
The coolant reservoir is mounted in the carriage. The operator
has the ability to refill the reservoir and to monitor the level
of coolant at this location. See Maintenance section for instruc-
tions.
