of operation.
1. Run diagnostic Tilt Drive test. If the test fails, check for
obstructions in the process gear box. Ensure the
process drive gears are correctly aligned. Replace the
process motor.
2. Run diagnostic Process Motor test. If the test fails
check for an obstruction in the process gears.
Replace the process motor.
3. Run the diagnostic Transfix Drive Slow test. If the test
fails, check for an obstruction in the process gears.
Replace the process motor.
