The conditioning board is located at the rear of the print carriage. It features an on-board temperat-
ure and humidity sensor. The temperature and humidity is monitored in the print area and dis-
played to the operator on the screen.
A break-off section of the board can be separated from the main board, connected using an exten-
sion cable and positioned at the customers discretion.
The board is supplied with 24 volts to the Digital I/O connector. On-board regulators reduce the
voltage to 12V and 5V.
The conditioning board also contains the electronics for the squeegee strain gauge mechanism,
supplying software with feedback on squeegee pressure.

7.3 CALIBRATIONS
7.3.1 Print Carriage Home Offset
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.
Before starting this procedure, ensure the stencil is removed from the machine.
To calibrate the print carriage home offset, carry out the following:
1. Select Menu.
2. Select Service\Calibration.
3. Select Print Carriage Home Offset.
4. The print carriage moves to the previous print carriage home offset position and the convey-
ors lift to print height.
5. Open the front cover.
