The Table Vacuum System
[64] Closing vacuum zone 4
Vacuum Zone Control Handles
The control handles determine the state of the vacuum zones. When the handle is vertical,
the zone is open and creates a vacuum in the related area. To close a zone, turn the control
handle a quarter turn clockwise to the horizontal position.
Masking the Vacuum Table
If your media does not cover all of a vacuum zone you must mask the area around the
media to create a closed vacuum system. Use scrap media or material that is equal to or
less than the thickness of the media to mask the table. You can tell when the vacuum is
sealed by the sound it makes and also by the vacuum gauge, which must read at least 20
"Hg.
Vacuum Table Foot Pedal
The vacuum foot pedal toggles the table vacuum on or off. It helps the operator to secure
the media on the vacuum table since it allows hands-free operation. The vacuum must
be turned on prior to starting a print, and the vacuum cannot be turned off until a print
is completed.
Vacuum Gauge
The vacuum gauge is located on the table. It provides a visual representation of the actual
pressure in the vacuum table system.
