7. Place a second steel rule (2) on the board clamp, butted up against the back edge of the
board clamp foil (3).
8. Ensure the measurement (4) from the back edge of the foil to the front face of the squeegee
mechanism is 31mm ±0.5mm
.
9. If the measurement is correct, go to Step 18.
10. Remove the steel rulers and close the front cover.
11. Press the System button.
12. Select the Print Carriage Home Offset parameter.
13. If the measurement taken in Step 7 is greater than 31mm, decrease the current offset by the
difference. If the measurement taken in Step 7 is less than 31mm
, increase the current offset
by the difference.
14. Select Accept.
15. Select Move To Home Offset.

7.3.2 Humidity Offset
The calibration ensures the accuracy of the on-board sensor. The offset also compensates for the
difference in humidity between the sensor location and the print medium on the stencil.
Before carrying out this calibration procedure ensure a stencil is fitted to the machine.
1. Open the front cover.
2. Place a calibrated digital humidity meter on the stencil near to the squeegees.
3. Turn the humidity meter on.
NOTE
The humidity meter needs to be in place for at least 2 minutes to acclimatize and give a reli-
able reading.
4. Close the front cover.
5. Press the System button.
6. Select Menu.
7. Select Service/Calibration.
8. Select Temperature And Humidity Offsets.
9. Note the humidity reading on the on-screen humidity display.
10. Ensuring 2 minutes have passed, open the front cover.
11. Remove the humidity gauge and note the humidity reading.
12. Close the front cover.
13. Press the System button.

14. Select Humidity Offset.
15. Calculate the difference between the humidity meter and the machine display.
NOTE
If the digital humidity meter reading is 48.45% and the machine humidity reading is 49.95%
then the offset needs to be +1.5%.
16. Set the humidity offset required.
