• Code: F1 16
• Description: Staple sorter holding motor trouble. During rotation of the holding motor, the rotation pulse is not detected for 0.05sec or more.
• Causes: Motor lock. Motor rotation abnormality. Overcurrent to motor Sorter control PWB abnormality
• Remedy: Check the holding motor operation with SIM3-3.

• Code: F1 17
• Description: ST pressure release HP trouble. ST paper exit roller pressure release trouble when turning on the power/initializing
• Causes: ST paper exit roller pressure release clutch abnormality ST paper exit roller pressure release clutch HP sensor abnormality
• Remedy: Stop the transport motor in SIM 3-3, turn on the STORCL to check that the pressure release roller operates. Check the STORHP sensor with SIM 3-2.

• Code: F1 18
• Description: Tray 3 paper exit paddler operation trouble. Tray 3 paper exit paddler operation trouble when turning on the power/initializing
• Causes: Tray 3 paper exit paddler solenoid abnormality Tray 3 paper exit paddler HP sensor abnormality Finisher control PWB trouble
• Remedy: Operate the transport motor with SIM 3-3 and turn on T3PDSL to check that tray 3 paddler operates. Check T3PDHP sensor with SIM 3-2.

• Code: F1 50
• Description: Non-support trouble in automatic detection of option connection (Sorter, finisher). In automatic detection of option connection, a non-support finisher or a sorter is detected.
• Causes: A non-support finisher or a sorter is connected to the copier.
• Remedy: Check the finisher or the sorter.

• Code: F1 80
• Description: Finisher power not supplied. 24V power is not supplied to the finisher PWB.
• Causes: Connector harness improper connection or disconnection Finisher control PWB trouble Power unit trouble
• Remedy: Check the sensor operation with SIM 3-2.

• Code: F2 00
• Description: Toner control sensor output open
• Causes: Connector harness trouble Connector unconnected.
• Remedy: Check connection of the toner control sensor. Check connection of the connector harness with the main PWB. Check for disconnection of the harness.

• Code: F2 02
• Description: Toner motor connector unconnected. Connection detection signal with toner motor is OFF
• Causes: Connector harness defective Connector disconnected
• Remedy: Check toner motor connector for connection. Check connector harness to main PWB for connection. Check harness for broken wire.

• Code: F2 31
• Description: Process control trouble (OPC drum surface reflection rate abnormality) Detail Usually the sensor gain is adjusted so that the output is a certain value, by reading the drum base surface with the image density sensor before starting process control. However, a certain output is not obtained by adjusting the sensor gain.
• Causes: Image density sensor defective
• Remedy: Check process control sensor output with SIM44-2. (Do not adjust) If the result is far different from the specified value, it suggests the sensor is defective. Check the sensor and harness. If the deviation is relatively small, check the sensor and drum surface for contamination.
