This section describes how to deal with two service codes:

  • SC325: Development motor error
  • SC395: Drum motor error

Cause

One or more deformed or dirty ground plates in the drum cleaning unit are causing grounding faults and generating electrical noise that is interfering with the motor control signals that control operation of the drive motor.

  • SC325 occurs most frequently when electrical noise interferes with the drive motor control signals.

Solution

  1. Inspect the four ground plates on the drum cleaning unit.
  2. Clean the plates if they are covered with toner or grease, and then replace any plate if it is deformed.
