7. Ensure that the locking clip on the pressure mechanism is pressed over to
the right and clicks into place, as shown in the figure below. This ensures
that the locking clip is in the correct position to secure the transfer head.
8. Locate and fit the ProFlow transfer head unit to the pressure mechanism by
means of the two locating dowels. Slide the unit onto the pressure mecha-
nism. Once the unit is slid fully home, it is secured by closing the locking clip.
9. Locate the two pneumatic connectors and one electrical connector sited on
top of the squeegee printhead mechanism by raising the light shroud. Plug
the electrical connection from the ProFlow unit into the electrical socket.
CAUTION
ELECTRICAL CONNECTION.
This electrical connection informs the
machine of ProFlow fitment and must always be connected whilst the
ProFlow unit is fitted otherwise damage may occur if machine is run.
Connect the pneumatic leads from the pressure mechanism to each respec-

tive left and right connector.
10. Connect the pneumatics and switch the machine to ON. To ensure that the
machine recognizes the ProFlow module, the following indications on the
machine MMI are evident:
a. During the boot up sequence the operator is prompted to fit the ‘ProFlow
cover’.
b. The soft key that previously indicated ‘Paste Load’ now indicates
‘Knead Paste’.
c. In Diagnostics the ProFlow menu page can be accessed.
11. Carry out the ProFlow Contact Position Setup in the Calibrations section
later in this chapter.
12. Select Setup on the MMI. Select Load Data and load the product file to be
printed.
NOTE
For an existing product, the product file has already been written. If the
product is new, either edit an existing or default file. (The Machine Program-
ming Chapter of the User Manual refers.)
13. If the loaded file is the correct file for the product this completes Squeegees
to ProFlow Replacement. If the loaded file has to be edited, proceed with
Step 14.
14. Select Edit Data on the MMI and adjust the following ProFlow parameters
as appropriate:
• Transfer Head Size
• Stencil Protection
• System Pressure
• Idle Paste Pressure
• Knead Paste Pressure
• Knead Off-image
• Knead Before Print

Squeegees to
ProFlow (Fixed
Head Machines)
Instances may occur when the machine is required to print using the ProFlow
module configuration. The following procedure details how to revert the
machine from squeegee use to the ProFlow configuration:
ProFlow Printhead
Mechanism
1. In Diagnostics ensure that the squeegees are homed. Position the print
carriage so that removal and fit is carried out within easy reach.
2. Switch the machine OFF and disconnect pneumatics.
3. If squeegees are fitted, remove to a safe stowage.
4. Remove the following squeegee mechanism connectors from the print
carriage, right hand side:
• 9PL16 - Front squeegee motor
• 9PL17 - Rear squeegee motor
• 9PL08 - Front and rear home sensors
• 9PL19 - Pressure amplifier (if fitted)
5. Loosen the four captive screws securing the squeegee printhead mecha-
nism to the print carriage, using a 4mm Allen key (figure refers). Carefully
