How to Use the Océ Arizona 600 Series XT Vacuum
System
Introduction
The Océ Arizona 600 Series XT uses a vacuum system to secure rigid media for printing on the
printer table. Two independent vacuum pumps provide vacuum to the table, which is divided into
multiple vacuum zones. Pump 1 provides vacuum to the A Zones and the Center Zone. The
operator can control vacuum flow to the Center Zone with the manual On/Off valve. Pump 2
provides vacuum to the B Zones. All XT printers are shipped with metric vacuum zones. It is
possible to change the configuration from metric to imperial in the field by a qualified service
technician (the technician who installs your printer can do this, if needed).
The independent control of the zones allows the operator to print in a Dual Origin mode with
minimal down time.
[55] XT Vacuum Zones
There are three A zones and three B zones as indicated in the illustration. These zones are
controlled by five vacuum handles. Zones B1 and A1 are always on when the vacuum is
activated. Zones A2, A3 and B2, B3 are controlled by the position of the two left and two right
vacuum handles. The Center zone is controlled by the middle vacuum handle. It determines if the
C zone is On or Off when the vacuum is active.
Purpose
The vacuum system holds the media in place on the printer table. The zones are arranged to
accommodate common media dimensions. If a zone is activated, you must mask off any part of it
that is not covered by the media.
NOTE
An active zone that is properly sealed will read 20" Hg or higher on the vacuum gauge. If the
vacuum gauge for an active zone reads below 10"Hg (34 kPa) and you have ensured that the area
is properly masked and taped off, you may have a leak in the vacuum system. However, keep in
mind that lower vacuum levels will be seen when the media is porous. Place a service call only
after you determine that the zone is correctly masked and the gauge reads consistently low.
