ProFlow Contact
Position Setup
To set up the ProFlow contact height position carry out the following procedures:
1. Ensure the machine has initialized, if not switch power OFF and ON and
allow the machine to initialize.
2. Load a stencil with an off centre image.
3. Fit an empty transfer head to the ProFlow pressure mechanism. Remove
the cover.
NOTE
Ensure wipers and skis are fitted to the transfer head.
CAUTION
MACHINE JAMMING.
In order to prevent the inadvertent jamming of squee-
gee mechanical mechanisms, the following procedure must be carried out
in the correct sequence.
4. Position a 0.1mm shim on the stencil under the transfer head.
5. Select Maint. (F8).
6. Select Calibrat ProFlow (F1).
The following window and menu bar is displayed:
NOTE
The ProFlow Downstop Position is only available on GSX, Lt and Infinity
machines only.
7. For fixed head machines go to Step 11, for GSX, Lt and Infinity machines
continue with Step 8.
8. Using the Next key (F4), highlight PFLOW DSTOP POS.
This parameter pre-tensions the squeegee suspension springs to provide
ProFlow with a zero pressure datum.

9. Using the Incr. and Decr. keys (F6 - F7), set the Downstop Position to
4.0mm.
10. Select Move to Position (F1), the downstop is driven to the position set.
11. Using the Next key (F4) highlight PFLOW CONTACT POS.
This parameter sets the height of the ProFlow printhead so that it just
touches the stencil surface.
12. Using the Incr. or Decr. keys (F6 - F7), set the Contact Position to 5.5mm
for fixed head machines and 4.0mm for GSX, Lt and Infinity machines.
13. Select Move to Position (F1), the ProFlow unit is driven to the position set.
NOTE
Correct contact height is when the shim is just held between the transfer
head wipers and stencil. At this position it is not possible to slide the shim
sideways past the transfer head skis. If correct contact height is not yet
achieved, carry out the following steps:
14. If correct contact height is achieved go to Step 18. If correct contact height
is not yet achieved, continue with Step 15.
15. Using the Incr. or Decr. keys (F6 - F7), increase or decrease the Contact
Position set height by 0.5mm (eg 5.0mm or 6.0mm for fixed head machines,
3.5mm or 4.5mm for GSX, Lt and Infinity machines).
NOTE
Normally the contact position is between the range of 4mm - 8mm (nomi-
nally 6mm) for fixed head machines and 2mm - 6mm (nominally 4.0mm)
for Infinity, GSX and Lt machines.
16. Select Move to Position (F1), the ProFlow unit is driven to the position set.
17. Repeat Steps 15 and 16, varying the set position, until the correct contact
height is achieved.
18. Select Exit (F8).
19. Select Exit (F8)
20. Open the front printhead cover and remove the shim. Remove empty
transfer head, if necessary.
21. Close the front printhead cover.
22. Press the System button.
