Causes and Solutions
  • pgain is set incorrectly

Solution:  Make sure that pgain is set at 192 (set carriage pgain).

  • carriage motor is failing on older machines

Solution:

  1. Turn the power off.
  2. Remove the belt from the carriage motor
  3. Rotate the motor by hand. It should rotate with even torque. You should be able to slightly feel the steps (200 per revolution) but there should be no tight spots.
  4. If the motor is failing, replace it. Inspect the old one for signs of overheating and report this to the Response Center Product Specialist.
