There are three A zones and three B zones as indicated in the illustrations. These zones arecontrolled by five vacuum handles. Zones B1 and A1 are always on when the vacuum isactivated. Zones A2, A3 and B2, B3 are controlled by the position of the two left and two rightvacuum handles. The C zone is controlled by the middle vacuum handle.The independent control of the zones allows the operator to print in a Dual Origin mode withminimal down time.NOTEUse the vacuum gauge to determine if a zone is properly masked. When the active zone isproperly masked the gauge will read at 20"Hg (68 kPa) or higher. Small leaks can reduce thisnumber and therefore the efficiency of the vacuum. Porous media can also degrade the vacuumeffect.If the vacuum gauge for an active zone reads below 10"Hg (34 kPa) and you have ensured thatthe area is properly masked and taped off, you may have a leak in the vacuum system. Place aservice call only if you determine that the zone is correctly masked and the gauge readsconsistently low.Procedure1. Place media on the table at the desired location (use the table rulers or the registration pins tohelp with placement - see Media Registration).NOTETo place media at the print Origin B (Origin A is the default) you need to set that upeither in the ONYX software or after the job is sent in the Print Job screen (this isexplained in the next section "How to Print with Dual Origin").2. Mask off any areas of the active vacuum zone(s) that will not be occupied by the media.3. Activate the zones you wish to use either with the icon on the command bar of the Print Jobmodule 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 buttonlocated near the vacuum gauges.Use the Arizona 13x0 XT Vacuum SystemChapter 6 - Operate the Arizona 13x0 XT 89
