Table Vacuum Controls

Table Vacuum Controls
Introduction
Your printer uses a low-flow, high-pressure vacuum system to secure media for printing on the
printer table. Two vacuum pumps are used to evacuate the air between the overlay and the table.
Air-feed ports in the table surface connect to the vacuum pumps through a series of manually
operated flow valves that are operated by turning control handles. These handles 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.

Vacuum Zone Control Handles
The control handles determine the state of the vacuum zones. When the handle is vertical, the
zone is open and creates a vacuum in the related area. To close a zone, turn the control handle a
quarter turn clockwise to the horizontal position.
Masking the Vacuum Table
If your media does not cover all of a vacuum zone you must mask the area around the media to
create a closed vacuum system. Use scrap media or material that is equal to or less than the
thickness of the media to mask the table. You can tell when the vacuum is sealed by the sound it
makes and also by the vacuum gauge, which must read at least 20 "Hg.
Vacuum Table Foot Pedal
The vacuum foot pedal toggles the table vacuum on or off. It helps the operator to secure the
media on the vacuum table since it allows hands-free operation. The vacuum must be turned on
prior to starting a print, and the vacuum cannot be turned off until a print is completed.
