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.
