Print Medium
Pressure Two pneumatically driven print medium pressure pistons are located on top of
the transfer head; during conditioning and printing these pistons exert an even
downwards force on the crosshead piston.
As it presses down on the print medium, the seal on the crosshead printer flares
out creating a pressurised environment within the conditioning chamber. This
flaring prevents any print medium from leaking past the seal.

Print Medium
Recharging
At the end of a print stroke, if the print medium demand sensor detects that the
print medium level is low, the ProFlow ATx system recharges the transfer head
from the print medium cartridge.
Figure 12-3 Demand Sensor
During the recharge process, the print rails remain raised to support the transfer
head, and system pressure is applied to the ProFlow ATx system to prevent any
leakage. The print medium pressure is released, raising the crosshead piston
and creating a void in the conditioning chamber. Pneumatic pressure is applied
to the print medium cartridge driving print medium to the transfer head inlet and
on to the Archimedes screw. The Archimedes screw rotates for a set period of
time delivering the print medium into the conditioning chamber. The rotating
conditioning grid prepares and distributes the print medium ready for applica-
tion.
