SC727-39B1st Fold Motor Error
  

Motor error (Encoder error)

This is reported as a jam error when detected for the first time. If it occurs again in a row, its SC code appears.

  
  • Motor defective
  • Motor harness entrapped (short circuit or breaking of wire)
  • Connector disconnected
  • Controller board defective
  

Remove the jammed paper or slip of paper from the tray, and check if the SC occurs by turning the main power OFF then ON, submitting a job, feeding paper, opening/closing covers, and input/output check. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step.

  1. Check if all connectors between the controller board and the motors are connected securely. Reconnect the connectors if they are disconnected, or loose. 
  2. Replace the harness if it is disconnected, or damaged.
  3. Check if the motor runs, has no overloads, and is properly driven. Replace the parts if there are any defects.
  4. Check if there are any signs of a short circuit. Replace the parts if there are any defects.
