Description: Tray Module Communication Fail RAP Communication error between Tray Module PWB and MCU PWB was detected.
Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF. Go to the BSD 3.2 - -MCU-Tray Module Communication. Check the connection between the MCU PWB P423 and the Tray Module PWB P/J541 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • Reload the machine software (GP 16). • Tray Module PWB (PL 11.13) • MCU PWB (PL 18.2)

Code: 059-314
Description: Control (Center) Thermistor Failure RAP The Control (Center) Thermistor has an open circuit.
Remedy: Y N Install the Fuser Unit securely. Check the resistance of the Center Thermistor between J621-5 and J621-1 (BSD 10.1). The resistance is 3k ohms or higher. Y↓N→Replace the Fuser Unit (PL 7.1). Check the Center Thermistor wiring between P/J411 and J621 for an open circuit or a short circuit (BSD 10.1). The wire between P/J410 and J621 is conducting without an open circuit or a short circuit. Y↓N→Repair the open circuit or short circuit. Replace the Fuser Unit (PL 7.1). If the problem persists, replace the MCU PWB (PL 18.2).

Code: 059-315
Description: Control (Center) Thermistor Over Temperature Failure RAP The Control (Center) Thermistor detected a temperature higher than the specified value.
Remedy: NOTE: When this fault occurs, NVM location 744-005 is set to 1, 2, or 3, depending on the fault. You must reset this location to 0 in order to clear the fault. Check the resistance of the Center Thermistor between J621-5 and J621-1 (BSD 10.1). The resistance is 3k ohms or higher. Y↓N→Replace the Fuser Unit (PL 7.1). Check the Center Thermistor wiring between P/J411 and J621 for an open circuit or a short circuit ( BSD 10.1). The wire between P/J410 and J621 is conducting without an open circuit or a short circuit. Y↓N→Repair the open circuit or short circuit. Replace the Fuser Unit (PL 7.1). If the problem persists, replace the AC Drive PWB (PL 18.2) before replacing the MCU PWB (PL 18.2).

Code: 059-316
Description: Rear Thermistor Failure RAP The Rear Thermistor has an open circuit.
Remedy: Check the installation of the Fuser Unit. The Fuser Unit is securely installed. Y↓N→Install the Fuser Unit securely. Check the resistance of the Rear Thermistor between J621-7 and J621-3 ( BSD 10.1). The resistance is 3k ohms or higher. Y↓N→Replace the Fuser Unit (PL 7.1). Check the Rear Thermistor wiring between P/J411 and J621 for an open circuit or a short circuit ( BSD 10.1). The wire between P/J410 and J621 is conducting without an open circuit or a short circuit. Y↓N→Repair the open circuit or short circuit. Replace the Fuser Unit (PL 7.1). If the problem persists, replace the MCU PWB (PL 18.2).

Code: 059-317
Description: Rear Thermistor Over Temperature Failure RAP The Rear Thermistor detected a temperature higher than the specified value.
Remedy: NOTE: When this fault occurs, NVM location 744-005 is set to 1, 2, or 3, depending on the fault. You must reset this location to 0 in order to clear the fault. Check the resistance of the Rear Thermistor between J621-7 and J621-3 (BSD 10.1). The resistance is 3k ohms or higher. Y↓N→Replace the Fuser Unit (PL 7.1). Check the Rear Thermistor wiring between P/J411 and J621 for an open circuit or a short circuit ( BSD 10.1). The wire between P/J410 and J621 is conducting without an open circuit or a short circuit. Y↓N→Repair the open circuit or short circuit. Replace the Fuser Unit (PL 7.1). If the problem persists, replace the AC Drive PWB (PL 18.2) before replacing the MCU PWB (PL 18.2).

Code: 061-320
Description: ROS Motor Fail RAP ROS ready is not detected within the specified time (10s). NOTE: When turning the power OFF, turn OFF the power switch first and then the main power switch.
Remedy: Turn the power OFF and check the following connections for open circuit, short circuit, and poor connection. After the check is complete, turn the power OFF and ON. • ROS Motor for ROS Motor Ready Signal: Component Control [061-001] • Between the MCU PWB P/J406 and the LDD PWB P/J 620 If the problem persists, reload the machine software (GP 16). If the problem persists, replace the following parts in sequence: • ROS (PL 3.1) • MCU PWB (PL 18.2)

Code: 061-325
Description: SOS Fail RAP SOS interval is found to be longer than the specified value (102% of the specified SOS interval) 5 consecutive times when checked by ROS software. NOTE: When turning the power OFF, turn OFF the power switch first and then the main power switch.
Remedy: 1. Turn the power OFF and ON. 2. Turn the power OFF and check between the MCU PWB P/J404 and the LDD PWB P/ J140 for open circuit, short circuit, and poor connection. 3. If no problems are found, replace the following parts in sequence: • If the problem persists, reload the machine software (GP 16). • ROS (PL 3.1) • MCU PWB (PL 18.2)

Code: 062-277
