How to Set Up a Print Job
zones are opened or closed using a quarter turn handle. Refer to the next section for details
on the dimensions and placement of the vacuum zones.
Mask Active Vacuum Zones Not Covered With Media
To hold the media to the table it is important to completely cover active vacuum zones
with either the media to be printed on, or a masking material. The masking material
should not be thicker than the media to be printed on. If a full bleed image is to be
printed, the masking material should be the same thickness as the media to be printed
on to prevent overspray from accumulating on the print head nozzle plates.
Turn On Table Vacuum
Click on the Vacuum button in the top right corner of the UI display to activate the table
vacuum. Also a vacuum foot pedal switch is provided to help secure the media on the
table vacuum. Step on the foot pedal to toggle the table vacuum on or off.
Note:
When the vacuum is switched off, wait a few seconds before you switch it on again.
Adjust Vacuum Bleed Valve, If Required
A bleed valve can be adjusted to reduce or increase the amount of vacuum suction on the
media. Less suction reduces artifacts caused by the suction when imaging on flexible
media. In most cases when printing on rigid material, full vacuum suction is desired.
Clean Media, If Required
If the media is dusty or dirty, clean it with an appropriate cleaner. If using a liquid like
isopropyl alcohol, allow sufficient time to dry prior to imaging.
Start Print
The Print button is located at the corner of the table where media is loaded. Press the
Print button to start the print job. If the job was selected, the media thickness confirmed
and the vacuum is turned on, printing will start after the ink and lamps reach operating
temperature.
