• Code: F1 08
• Description: Sorter staple shift motor trouble. Staple motor drive trouble
• Causes: Motor lock Motor speed error Overcurrent to motor Sorter control PWB defective
• Remedy: Check staple motor operation with SIM3-8.

• Code: F2 02
• Description: Toner motor connector disconnected. 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 base surface reflection factor is improper). 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 SIM44-03. (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.

• Code: F2 32
• Description: Process control trouble (drum marking sensor defective). Usually the sensor gain is adjusted so that the output is a certain value, by reading the drum base surface with the drum marking sensor before starting process control. However, a certain output is not obtained by adjusting the sensor gain.
• Causes: Drum marking sensor defective Improper connection of harness between PCU PWB and drum marking sensor Drum marking sensor contaminated OPC drum cleaning improper Charging voltage improper
• Remedy: Check process control output with SIM44-02. (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.

• Code: F3 12
• Description: Upper cassette lift-up trouble. UPED does not turn on within the specified time. ULUD does not turn on within the specified time.
• Causes: UPED or ULUD defective Upper cassette lift-up motor defective Improper connection of harness between PCU PWB, lift-up unit, and paper feed unit.
• Remedy: Check UPED, ULUD and their harness and connector. Check lift-up unit.

• Code: F3 22
• Description: Lower cassette lift-up trouble. LPED does not turn on within the specified time. LLUD does not turn on within the specified time.
• Causes: LPED or LLUD defective Lower cassette lift-up motor defective Improper connection of harness between PCU PWB, lift-up unit, and paper feed unit.
• Remedy: Check LPED, LLUD, their harnesses and connectors. Check lift-up unit.

• Code: F5 00
• Description: Copy lamp lighting error. Copy lamp does not light despite the output of lighting signal. Copy lamp lights without the output of lighting signal.
• Causes: DC power supply defective Control PWB defective Copy lamp defective Improper connection of harness between PCU PWB, DC power supply unit and copy lamp unit
• Remedy: Check copy lamp for lighting with SIM5-3. Check harnesses and connectors between PCU PWB, DC power supply and copy lamp unit

• Code: F9 01
• Description: PRT DRAM trouble. DRAM trouble inside optional printer board (checked when power is turned ON).
• Causes: Not possible to access because DRAM module is broken. DRAM module improperly installed
• Remedy: Check with SIM67-1.
