Pressure
Calibration
Squeegee pressure calibration is carried out on machines fitted with the Pres-
sure H/W option after the following circumstances:
• The squeegee mechanism is replaced
• The strain gauge bridge in the squeegee mechanism is replaced
• The rising table sensors have been replaced or adjusted
A force meter calibration jig and squeegee pressure plate are required to
perform the squeegee pressure calibration.
NOTE
1. Ensure that the rising table print reference height is set correctly before
commencing, (the calibration relies upon accurate positioning of the table to
make a reference).
2. Ensure that the Pressure H/W parameter in Setup Machine - Options
Parameters is set to FITTED.
Use the following procedure to calibrate the squeegee pressure:
WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN WORKING IN
THE TOOLING AREA OF THE MACHINE TO AVOID INJURY. THE FOILS ON THE
FRONT AND REAR BOARD CLAMPS ARE VERY SHARP.
1. Ensure the machine has initialised, if not switch power OFF and ON to allow
the machine to initialise.
2. Remove the screen from the machine.
3. Remove the tooling from the manual tooling plate.
4. Select Maint..
5. Select Calib Machine.
6. Select Pressure.
7. Select Calibrat Readings. The message ‘Initialising Table and Rail for
Pressure Calibration’ is highlighted. The print carriage moves to the
calibration position, the rear rail moves to home position, the table homes
and the board clamps are closed.
8. The machine cover is unlocked and the message ‘Fit Pressure Calibration
Jig’ is highlighted, the following window is displayed:
9. Open the front printhead cover/shutter.

12. Fit the squeegee pressure plate to the rising table ensuring that the locating
dowels insert the holes of the rising table.
NOTE
During the squeegee pressure calibration the dwell height of the rear
squeegee is 15mm regardless of the set up value. This height is set during
calibration only.
13. Switch the force meter ON and check the reading is 0kg, (ensure the force
meter is not in contact with the squeegee pressure plate).
14. At the MMI select Continue. The front squeegee mechanism steps down
until a change in pressure is detected and continues stepping down until the
pressure value stored on the machine is reached. If the calibration jig
displays 10kg, go to Step 16.
15. On the MMI, select Jog Rig.
16. Use the left and right jog buttons to move the front squeegee mechanism up
or down until the calibration jig displays 10kg.
NOTE
Achieving exactly 10kg may not be possible as some calibration jigs display
down to three decimal places.
17. Select Set Calib.. The message ‘Printer configuration data file saved’ is
highlighted.
18. On completion of calibration select Exit button, the front squeegee mecha-
nism moves to the home position. The message ‘Confirm that the pres-
sure calibration jig has been removed.’ is highlighted.
19. Remove the calibration jig and the squeegee pressure plate from the
machine. On completion select Yes, the table resets, the print carriage
moves to home position, board clamps open and the rear rail moves to the
board width setting.
20. Carry out the Squeegee Reference Height (Pressure Feedback) calibration.
Squeegee
Reference Height
(Pressure
Feedback)
Squeegee reference height is carried out on machines fitted with the Pressure
H/W option after the following circumstances:
• Squeegee pressure calibration
• Squeegee change
Use the following procedure to set the squeegee reference height:
NOTE
If a Ptest.dat file is required, Data Logging must be set to On. To achieve this
select Maint., select Test Cycles and select Data Log On.
1. Remove the screen from the machine.
2. Select Maint..
3. Select Calib Machine.
4. Select Pressure.
5. Select Calibrat Heights. The message ‘Ensure that the correct squee-
gees are fitted!’ is highlighted.
