  Motor Failure: #A1-1113. Turn off then on. Call for service if the problem persists.
• Causes: Feed/MP motor operation is abnormal.
• Remedy: • A1–1111 : Feed/MP motor is stopped but machine recognizes it as operational. • A1–1113 : Feed/MP motor is operating but machine recognizes status as "Stopped".
  1) Turn the machine off then on. If the error persists, check the following. 2) Open the side cover. Check if there are any foreign substances or paper around Feed/MP unit. 3) Remove the rear cover. 4) Check the connection between the motor and main board. 5) If the connection is OK, enter SVC mode. Execute the motor test. (Diagnostics > Engine Diagnostics > Engine Test Routines) a) If the motor is not operational, i) Check the motor signal(3.3V). If the signal is abnormal, replace the main board. ii) Check the power(24V). If the power is abnormal, check the SMPS board. If the SMPS board is defective, replace it. iii) If the motor signal and power is normal, replace the Feed/MP motor. b) If the motor is operational, replace the main board.
