NOTE
Immersion of any part of the ProActiv unit in liquids causes irreparable damage
to the unit. It may also cause permanent damage when fitted to the printer.
1. Remove the ProActive squeegee units using the Removal procedure (pre-
vious section).
2. Using an IPA impregnated wipe (Part No: 11508), thoroughly clean all
exterior surfaces of each squeegee.

OVERVIEW
11.2 Technical Reference Manual Chapter Issue 2, Aug 14
The ProFlow mechanism is driven backwards and forwards across the stencil
by the print carriage applying printable material directly onto the stencil. This
alleviates the need for squeegees and a paste dispenser.
The ProFlow mechanism is raised and lowered, to the stencil by means of a
stepper motor, applying a downward force directly onto the stencil providing a
positive seal between the transfer head and stencil. This eliminates leakage of
print material above the stencil.
Paste pressure (pneumatic), is applied to the piston crosshead exerting a force
onto the print material which, in turn, forces print material into the ProFlow
conditioning chamber and into the stencil apertures.
As the unit moves across the stencil the trailing wiper, within the transfer head,
lifts the print material from the stencil surface, clearing the stencil of print
material and creating a rolling movement of material within the conditioning
chamber.
