Characteristics of the printer 9040 IP65
A stream of air constantly circulates inside the printer and keeps the unit pressurized to
prevent the ingress of dust and humidity inside the printheads and in the different
compartments of 9040 IP65 model printers.
Air is introduced via a high capacity electrovalve for 30 seconds every time the printer is
started to clear any vapors from inside the unit. The printer will not start until this stage is
completed.
Compressed air must be available to allow the printer to be started. If the pressure drops
when the printer is in service, a safety pressure switch flags a "ventilation fault" and
automatically triggers a shutdown procedure of the printer.
The air taken into the printer must by clean, dry and oil-free, at a pressure of between 5
and 8 bar (72.5 to 145 psi) and a minimum flow rate of 15,000 Nl/h (9 SCFM). The printer
incorporates an automatically draining filter.
NOTE A flow rate of 15,000 Nl/h (9 SCFM) is needed for thirty
seconds on start-up.
When the printer is in service, air consumption is around
1,500 Nl/h (0.882 SCFM) for single-head models and
1,900 Nl/h (1.117 SCFM) for twin-head models.
The air intake is at the back of the printer on a 1/8 G threaded
female connector.
CAUTION The printer air supply must meet the following requirements to
provide the flow rates indicated above:
- Air tubing of over 4 mm in diameter,
- length of air tubing less than 5 meters,
- no elbows,
- valve bore diameterlarger than 8 mm.
