Cause: The drum motor cannot move to the required position.
Action:
1. Remove the crashed substrate and restart the machine.
2. Lower the substrate speed.
3. Check whether the drive drum turns smoothly (first turn the power off and
place the cam rollers in the up-position).
4. If problems continue, call your HP representative.
Cause: The motor driving the machine head cannot move to the required position.
Action:
1. Remove the crashed substrate and restart the machine.
2. Lower the speed and/or the knife pressure.
3. Check whether the head moves smoothly (first turn the power off and position
the cam rollers on the outer edges of the substrate).

Cause: OPOS does not sense markers, or senses values with which it cannot work.
Action:
1. Check the OPOS parameters and compare them to the printout. Set correct
parameters.
2. Check whether there is dust on the sensor tip.
3. Set substrate calibration OPOS to default and run the OPOS test found on the
manual CD.
4. Check the connection cable which runs from the head to the PCB.
5. Check the machine with another head (OPOS).
6. Check reflection values with OPOS monitor.
7. Check the flat cable going from the head to the PCB.
8. If problems continue, call your HP representative.
