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.
Procedure
1.
Place media on the table.
NOTE
To place media at the Print Origin for the B Zone requires an offset at
1830mm (this must be set either in the ONYX software or the Print Job
screen and can be entered in millimeters, even when the interface is set to
Imperial units).
2. Mask off any areas of the active vacuum zone(s) that will not be occupied
by the media.
NOTE
The media can occupy more than one zone, but if a zone will be active, all
of the area not covered by the media must be masked so that all vacuum
holes are covered.
If the Center Zone is not occupied by media it can be turned Off with the
manual valve located at the Zone 1 end of the printer.
3. Activate the zones you wish to use either with the icon on the command
bar of the Print Job module or with the matched foot switch (A or B) on the
floor.
4.
Start the print job either with the Start icon on the command bar or with
the Print Start button located near the vacuum gauges.
5.
De-activate the zones with either the icon or the foot switch once the
image is printed.
6. Remove the media.
