Code :

Code: F2 32
Description: Process control trouble (Drum marking scanning trouble). 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: F2 37
Description: Drum marking sensor gain adjustment error. When the drum marking area surface is scanned with the drum marking sensor before starting process control and the sensor gain is adjusted until a constant output is provided, the output is not constant though the sensor gain is changed.
Causes: Drum marking sensor trouble Improper connection between PCU PWB and drum marking sensor Drum marking sensor is dirty OPC drum cleaning trouble
Remedy: Perform the gain adjustment of process control sensor with SIM 44-2. If ERROR is displayed, it may be a breakdown. Check the sensor and the harness. When the adjustment is completed, check the drum surface conditions.

Code: F2 39
Description: Process thermistor breakdown. The process thermistor is open.
Causes: Process thermistor abnormality Improper connection of the process thermistor bar PCU PWB abnormality
Remedy: Check connection of the process thermistor harness and connector. Check the PCU PWB.

Code: F3 12
Description: Copier top stage CS 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: Copier bottom stage CS 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: F9 00
Description: Printer communication trouble (ICU detection). Communication setup error, framing/parity/protocol error
Causes: Slave unit PWB connector improper connection Slave unit PWB – ICU PWB harness trouble Connector pin breakage of the motor PWB of the slave unit PWB Slave unit ROM trouble. no ROM, ROM reverse insertion, ROM pin breakage
Remedy: Connect the connector of the slave unit PWB and the ICU PWB. Check the connection and the harness. Check the grounding of the copier. Check the ROM of the slave unit PWB.

Code: F9 01
Description: PRT DRAM trouble. Option printer PWB DRAM trouble (Check when turning on the power.)
Causes: DRAM module is broken and access cannot be made. DRAM module improper installation
Remedy: Check with SIM 67-1.

Code: F9 03
Description: Network card trouble. Network card self test trouble.
Causes: Network card defecft. Printer PWB defect. Network card connector connection defect.
Remedy: Check the Network card connector. Replace the printer PWB. Replace the Network card.
