Using the Media Vacuum System
The vacuum table is the platen that holds the media in place during printing. The table
is a thin hollow rectangular aluminum box with aluminum box extrusions forming a
perimeter frame, two 1/8" aluminum skins forming the top and bottom surfaces, and
aluminum honeycomb in the interior supporting the skins. The top surface is drilled with
1mm diameter vacuum holes with a 0.2 “ (5mm) diameter counterbore to allow air flow
into the table and create a vacuum hold-down for the media.
There are four zones on the table platen. Each zone is 32” (81cm) x 62” (158cm). The
first zone is always available while the other three must be selected by the operator. Turn
on the vacuum pump by pressing the VACUUM button on the control panel. This causes
any media placed over Zone 1 to be held in place by the ensuing suction. Activate Zone
2 by turning the right control handle counter-clockwise 90 degrees. The center control
handle activates Zone 3 and the left control handle is for Zone 4. Press the Vacuum
button on the control panel again to turn off the vacuum pump. The position of the
individual control handles determines whether zones 2, 3, or 4 are activated when the
vacuum system is on.
