90° Tilt Setup
The bulk ink supply allows the print head to be tilted 90° from vertical versus the 45° limita-
tion with a standard print cartridge. The relative positioning between the reservoir and print
head needs to be maintained for the print head to function properly. Standard bracketry
may be used to mount the print head in this orientation, however it may be necessary to
extend the tubing between the reservoir and print head (reference the print down setup for
instructions).
Operation
●
Operating pressure of the bulk ink supply is 4-5 psi. Once pressure drops below 4 psi the air
pump will turn on and pressurize the ink supply up to 5 psi.
●
If the pump can not achieve 5 psi after running for 15 seconds the system goes into an "Ink
Low" state (beacon will turn on solid) indicating the 350 ml ink cartridge is empty. The print
heads will continue to print because there is still ink in the print head cartridges; this allows
ample time to change the 350 ml ink cartridge.
●
Changing the 350 ml bulk ink cartridge:
○
Press the pressure
relief valve on the
back of the bulk ink
system to depres-
surize the ink car-
tridge.
○
Push in and up
slightly on the car-
tridge to release it
from the holster.
○
Insert the new car-
tridge. The system
will detect the new
cartridge and begin
pressurizing auto-
matically.
●
Maximum print heads
per ink system: four 1"
print heads, eight 1/2”
print heads, or any combination of the two totaling eight print cartridges.
