Vacuum Gauge
A vacuum gauge is located on the table. It provides a visual representation of the actual pressure
in the vacuum table.
NOTE
If the vacuum gauge reads below 40"H
covered with I/O paper or similar non-porous media, there may be a leak in the vacuum system.
If this occurs place a service call.
Printing on porous media or reducing the vacuum vent settings may cause the gauge to show
less the 40"H
Print Zones
There are two Print Zones, A and B. Each zone has it own origin and registration pins.
Vacuum Foot Pedal Switch
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
There are 2 foot pedal switches for the printer. Each foot pedal provides the following
functionality:
• If the pumps are "Off" the foot pedal powers them "On" and opens the vacuum valves.
• If the pumps are On, the pedal alternates between opening and closing the vacuum valves. To
turn the pumps Off click on the Pump icon in the printer UI.
• Raises or lowers the media registration pins (if the switch depressed for 2 seconds) in its
respective print zone.
Vacuum Pumps
Three vacuum pumps are connected to the vacuum table. Click on the Vacuum Setting icon to
open the vacuum Setting window. Here the number of active vacuum pumps can be set. The
vacuum pumps will remain on throughout a print job or jobs. Three vacuum valves control flow
from the vacuum pumps to the table. Opening and closing the vacuum valves to turn On and Off
vacuum to the table is done by either using the foot pedal switches or clicking on the Vacuum
icon on the UI. The Pump icon is used to turn On and Off the vacuum pumps that are active. It is
not efficient for the vacuum pumps to be turned On and Off between prints because it takes time
for each pump to reach full vacuum.
NOTE
The pumps will NOT turn off automatically after a period of inactivity. Pumps must be powered
off by the UI icon or the AC power switch on the pump box.
Vacuum Vents
Vacuum vents are provided for printing on corrugated cardboard. The vents can be used to
reduce the level of vacuum and air flow in the table. This control enables printing closer to the
edges of corrugated cardboard. There are 4 levels of venting provided: 0%, 25%, 50%, 75%, 100%.
Click on the Vacuum Setting icon to open the vacuum Setting window. Here the level of venting
can be set.
When printing close to the edge of the media, open the vents as much as possible while still
maintaining media hold-down. Refer to the vacuum gauge to reach the ideal reading of 10"H
15"H O, depending on the media and how close to the edge you print .
