4. Locate the pneumatic manifolds and the pneumatic connections at the rear

of the APC module.

5. Disconnect the pneumatic connectors; to remove, push the collar in while

simultaneously pulling the tube out.

6. Remove pneumatic tubing and sensor loom from module mounted cable

ties.

CALIBRATIONS

Board Transport

Belt Speed

NOTE

Where the printer is connected to inline equipment, make sure that the FMI

functionality is turned OFF before proceeding.

The front and rear board transport belts are driven independently by two

variable speed motors. Inevitably, one motor drives faster than the other motor.

It is necessary to calibrate these motors so that they drive at the same speed.

Feeder motor speed is measured using a tachometer on the input or output

pulley and adjusted by a potentiometer control on each motor.

1. Remove the right hand safety cover to gain access to the transport belt

motors.

2. Select Maintenance.

3. Select Diagnostics.

4. Use Next or Previous to highlight Rail System.

5. Select Select Module.

6. Use Next or Previous to highlight Rail System.

7. Select Run Diagnost.
