Figure 12-4 Transfer Head Unit Status During Charging Action
The Archimedes screw and conditioning grid stop rotating, the system pressure
is relaxed, and print medium idle pressure is applied.
NOTE
Recharging the transfer head is an automatic process and requires no interven-
tion from the machine operator.
Rolling Conditioning During recharging, the conditioning grid rotates. This action keeps the print
medium in the optimum condition required for successful printing.
During the print process the rotation of the conditioning grid, working together
with the print medium pressure, forces print medium into the apertures of the
stencil.

Transfer Head
Base Cover
The ProFlow ATx system has a base cover which is fitted to the base of the
transfer head to keep the print medium sealed during:
• Non-operation
• Fitting/Removal of the Transfer Head
• Temporary Storage
NOTE
Temporary storage time is dependent on the print medium used, see manufac-
turers recommendations. If storage time exceeds the recommendation, the
ProFlow transfer head must be emptied and cleaned.
The transfer head base cover:
• Prolongs the life of the print medium by sealing the transfer head
• Prevents the operator from coming into contact with the print medium when
removing or fitting the transfer head
• Prevents damage to the wiper blades and skis when removing or fitting the
transfer head
• Prevents print medium from dripping into the printer when removing or
fitting the transfer head

With the base cover fitted and locked to the transfer head, a seal is created
between the wiper blades, the side skis and the base cover. A transfer head
sealing plug is locked into the transfer head inlet, completing the seal and
protecting the print medium.
ProFlow ATx
Stencil Support
The ProFlow ATx stencil support option provides extra support for the stencil
when printing boards which are narrower than the transfer head. This extra
support prevents print medium smearing, and also the reduction of the pressure
within the transfer head.
