11. Remove the screen from the machine.

12.Close the front printhead cover.

13.Press the System button.

14.Select Calibrate Heights.

15.The message ‘Ensure that the correct squeegees are fitted!’ is dis-

played.

16.If the correct squeegees are fitted, select Continue.

17.The following machine sequence is carried out:

a. The rails are checked for the presence of a board.

b. The rising table is driven to print height.

c. The board clamps are closed.

d. The print carriage drives the front squeegee over the front rail.

e. The rear squeegee is driven down to dwell height.

f. The front squeegee is driven down by the stepper motor until contact with

the board clamp is made.

g. The front squeegee continues to be driven down until a 2kg pressure

difference is detected, the motor pauses.

h. The amount of steps (the stepper motor took to get to this position) and

the pressure are recorded.

i. The stepper motor drives downwards another 15 steps, this is recorded

with the pressure detected. This is repeated a further 18 times to achieve

a total of 20 results.

18.The rear squeegee is calibrated in a similar manner.

19.The message ‘Calibrate Squeegee heights complete’ is displayed.

20.Select Back.

21.Select Back.

22.Select Maintenance.

23.Select Test Cycles.

24.Select Data Logging Off.

25.Select Back.

26.Select Back.

Ptest.dat File The file displays 20 front squeegee readings followed by 20 rear squeegee

readings, showing the relationship between steps (displacement) and pressure

applied. From the readings taken, the front and rear pressure factors and

squeegee reference heights are calculated. At the end of the file, 5 readings of

flood pressure and reference height readings are displayed (these are also

listed in the Config.txt file).

The Ptest.dat file is located on the hard drive of the machine PC. To view the

file carry out the following procedure:

1. From the Windows start menu, select Programs - Accessories - Windows

Explorer.
