How to Manage the Media Vacuum
The Table Vacuum System
Introduction
Your printer uses a low-flow, high-pressure vacuum system to secure media for printing
on the printer table. A vacuum pump is used to evacuate the air between the overlay and
the table. Air-feed ports in the table surface connect to the vacuum pump through a series
of manually operated flow valves. These valves are used to activate or shut down the
vacuum zones. In order for the system to work effectively, during printing all the circular
holes on the top surface of the overlay sheet connected to an active vacuum zone must
be covered. This creates a closed vacuum system.
The printer is shipped from the factory configured with six vacuum zones. Zone 1 is always
on and zones 2 to 6 can be open or closed, based on the position of the zone control
handles. The printer is ordered with your choice of vacuum zone configurations, either
Metric or Imperial units. These zones are set up to support common media sizes.
