c. In Diagnostics the ProFlow menu page can be accessed.

12. Carry out the ProFlow Contact Position Setup in the Calibrations section

later in this chapter.

13. 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.)

14. 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 15.

15. 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

• Clean After Knead

• Knead After Replenish

If Advanced ProFlow is set to enabled, adjust the following ProFlow param-

eters as appropriate:

• FWD Start Speed

• FWD End Speed

• RWD Start Speed

• RWD End Speed

• FWD Start Pressure

• FWD End Pressure

• RWD Start Pressure

• RWD End Pressure

If Advanced ProFlow is set to disabled, adjust the following ProFlow param-

eters as appropriate:

• Front Print Speed

• Rear Print Speed

• Print Paste Pressure

Programming chapter of the User manual.

Squeegees to

ProFlow (Infinity)

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:

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. Using a 4mm Allen key, remove the front and rear squeegee 'I' bars, (access

to the screws for the front ‘I’ bar is gained by raising the light shroud on it’s

hinge - Figure below refers).

5. Using the existing screws, fit and secure the ProFlow downstop to the front

squeegee 'I' bar mounting position. Ensure that the downstop arms fit

above, to rest upon, the printhead linear webs.

6. Fit the pressure mechanism part of the ProFlow unit to the rear squeegee

mounting plate (where the 'I' bar normally fits) by means of the two securing

bolts. These bolts are easier accessed by fitting the unit in the unlatched

position. Tighten using a 5mm Allen key.

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-
