• Code: 042-323
• Description: Drum Motor Failure RAP The Main Motor is not rotating at the specified speed.
• Remedy: Close the LH Cover and the Front Cover. Execute Component Control [042-001 Drum Motor ON]. The Drum Motor can be heard. Y↓N→Go to BSD 9.5 Drum Drive Control and the wires between the MCU PWB ( P/J407 and P/ J408) and the Main Motor ( P/J202 and P/J207) for an open or short circuit. If OK replace the Drum Motor (PL 3.2) Check the installation of the Main Drive Assembly (PL 3.1 and PL 3.2). The Main Drive Assembly is installed correctly. Y↓N→Install the Main Drive Assembly correctly. Check the wire between P/J407-1 and P/J207-8 for an open circuit or a short circuit (BSD 9.5 Drum Drive Control). The wires are conducting without an open circuit or a short circuit. Y↓N→Repair the open circuit or short circuit. Manually rotate the Drum Motor rotor. It rotates smoothly. Y↓N→Check for foreign substances that are interfering with operation or installation failure. Foreign substances or installation failure are found. Y↓N→Replace the Main Drive Assembly (PL 3.1). Remove the foreign substances that are interfering with operation and correct the installation failure. Replace the Main Drive Assembly (PL 3.1) If the problem persists, replace the MCU PWB (PL 18.2).

• Code: 042-400
• Description: Odor Filter End Of Life
• Remedy: Replace the Odor Filter and reset the HFSI Value (HFSI Counter) [954-860].

• Code: 042-401
• Description: VOC Filter End Of Life
• Remedy: Replace the VOC Filter and reset the HFSI Value (HFSI Counter) [954-861].

• Code: 045-310
• Description: Image Ready NG RAP A Controller image preparation failure was detected.
• Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF and check whether there is poor connection or foreign substances at the following connectors. • Between the ESS PWB P/J320 and the MCU PWB P/J402 • Between the ESS PWB P/J1323 and the MCU PWB P/J403 If no problems are found, replace the following parts in sequence: • Check the sw version of the controller sw - update if required • MCU PWB (PL 18.2) • ESS PWB (PL 35.2)

• Code: 045-311
• Description: Controller Communication Fail RAP Communication error between ESS PWB and MCU PWB was detected.
• Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF and check whether there is poor connection or foreign substances at the following connectors. • Between the ESS PWB P/J320 and the MCU PWB P/J402 • Between the ESS PWB P/J1323 and the MCU PWB P/J403 If no problems are found, replace the following parts in sequence: • Check the sw version of the controller sw - update if required • MCU PWB (PL 18.2) • ESS PWB (PL 35.2)

• Code: 047-211
• Description: Exit 1 OCT Home Fail RAP After the Exit 1 OCT Motor has run for the specified operation time, the Exit 1 OCT Home Position Sensor does not turn ON.
• Remedy: Turn the power ON and enter the Diag mode. Turn ON Component Control [077-102] (Exit 1 OCT Home Position Sensor). Move the OCT Chute manually to block/clear the light path to the Exit 1 OCT Home Position Sensor. Does the display change between High/Low? Y↓N→Go to BSD 10.6 - Exit 1 Drive/OCT Control to check the Exit 1 OCT Home Position Sensor (PL 17.1) for an open or short circuit. Press the Stop button. Turn ON Component Control [077-010] and Component Control [077- 011] alternately. Does the OCT 1 Chute move forward and backward? Y↓N→Remove the Rear Lower Cover. Is the voltage between the MCU PWB P/J417-11/12 (+) and the GND (-) +24VDC? Y↓N→Go to +24VDC Power RAP. Turn the power OFF and check the Exit 1 OCT Motor Gear for blockage and the OCT Chute for damage. Also, check the connection between the MCU PWB P/J417 and the Exit 1 OCT Motor P/J217 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • Exit 1 OCT Motor (PL 17.1) • MCU PWB (PL 18.2) Press the Stop button. Turn the power OFF and replace the MCU PWB (PL 18.2).

• Code: 047-216
• Description: Finisher Communication Fail RAP Communication failure between the Finisher and the IOT was detected.
• Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF and check the connection between the MCU PWB P/J422 and the Finisher PWB P/J8704 (Integrated) or J8889 (External) for open circuit, short circuit, and poor contact. Also, check the power supply at the Finisher. If no problems are found, replace the MCU PWB (PL 18.2).

• Code: 047-217
• Description: HCF Communication Fault Communication failure between the HCF and the IOT was detected.
• Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF and check the connection between the MCU PWB P/J419 and the HCF PWB J 800A and J 800B for open circuit, short circuit, and poor contact. Also, check the power supply at the HCF. If no problems are found, replace the HCF PWB (PL 10.8) before replacing the MCU PWB (PL 18.2).
