[51] 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.
