How to Manage the Media Vacuum
The Media 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. Three 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
either the default single zone or any custom 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. A bleed valve is provided to adjust the level of vacuum, if needed.
Default Vacuum Zones
The printer is shipped from the factory configured with one large vacuum zone that ac-
commodates the maximum media size. There are two suggested custom vacuum zone
configurations, one for Metric and one for Imperial units. These zones can be set up for
common media sizes, and can be modified by placing a call to a service technician.
