Calibration
Squeegee pressure calibration is carried out on machines, fitted with the
Pressure Hardware 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 Hardware parameter in Maintenance\Machine
Setup\Options 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. Select Open Cover Commands.
2. Select Carriage To Rear.
3. Select Unload Screen.
4. Open the front printhead cover.
5. Remove the stencil from the machine.
6. Remove the tooling from the manual tooling plate.

8. Press the System button.
9. Select Back.
10. Select Maintenance.

The rails are checked for the presence of a board, the print carriage moves
to the calibration position, the rear rail moves to home position, the table
homes and the board clamps are closed.
