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 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. 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.
