Description: Suction Filter EOL The Suction Filter has reached the end of life.
Remedy: 1. Replace the Suction Filter.
Code: 310.329
Description: Fuser Cut Fail After the fuser is replaced with new one, the fuse (fuse1) did not change to Open state in 1 sec.
Remedy: • Turn the power Off and check whether the Fuser Assembly is installed properly. Power back on and if the error has not cleared, follow the procedure. Remove the Fuser Assembly and check the resistance between pins A1 and A2 on the Fuser Assembly. Is the readying ~0 ohms? Y↓ N→Check the wiring between DJ600-A10 and J431-2 on the MCU PWB. Is the resistance ~0 ohms? Y↓ N→Repair the wiring. Is the voltage between DJ600 A11 (+) and the GND (-) +3.3VDC? Y↓ N→Is the voltage between J431-1 (+) and the GND (-) +3.3VDC? Y↓ N→Repair the wiring Replace the MCU PWB. Replace the MCU PWB. Replace the MCU PWB.
Code: 310.330
Description: Fuser Motor Fault. The Fuser Drive Motor revolution failure was detected.
Remedy: • Turn the power Off and check whether the Fuser Assembly is installed properly. • With the Fuser in closed state, rotate the Roller manually to check for loading. Turn the power Off and remove the Rear Upper Cover. Disconnect the connector P592 of the MD PWB and open the Chassis Assembly. Turn the power On and enter Service Diagnostics Menu (Entering Service Diagnostics). Turn On dc330 Component Control [010-006] (Fuser Drive Motor). Does the Fuser Drive Motor rotate? Y↓ N→Is the voltage between the Fuser Drive Motor P/J242-1 (+) and the GND (-) +24VDC? Y↓ N→Go to +24VDC Power RAP. Is the voltage between the Fuser Drive Motor P/J243-1 (+) and the GND (-) +5VDC? Y↓ N→Go to +5VDC Power. Turn the power Off and check the connection between the MD PWB P/J525 and the Fuser Drive Motor P/J243 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • Fuser Drive Motor • MD PWB • MCU PWB Press the Stop button. Check the operation of dc330 Component Control [094-012] (1st BTR Contact) and dc330 Component Control [094-013] (1st BTR Retract) alternately. Does the Fuser Drive Motor rotate? Y↓ N→Turn the power Off and check the 1st BTR Contact/Retract Gear for blockage or damage. Turn the power Off and check the connection between the Fuser Drive Motor P/J243-8 and the MD PWB P/J525-A1 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • MD PWB • MCU PWB
Code: 310.360
Description: IH Driver Input High Voltage Fault. The input voltage of the IH Driver is high voltage (150VAC or higher). (Status code 0x1 is received)
Remedy: Turn the power Off. Remove the Right Cover and remove the Front LVPS Fan. Turn the main power On (turn On the Main Power Switch). Is the voltage between the Main LVPS P/J6-1 and J6-3 100VAC? Y↓ N→Go to AC Power RAP. Turn the main power Off and replace the following parts in sequence: • IH Drive PWB • MCU PWB
Code: 310.361
Description: IH Driver Input Low Voltage Fault. The input voltage of the IH Driver is low voltage (80VAC or lower). (Status code 0x2 is received)
Remedy: Turn the power Off. Remove the Right Cover and remove the Front LVPS Fan. Turn the main power On (turn On the Main Power Switch). Is the voltage between the Main LVPS P/J6-1 and P/J6-3 100VAC? Y↓ N→Go to AC Power RAP. Turn the main power Off and replace the following parts in sequence: • IH Driver PWB • MCU PWB
Code: 310.362
Description: IH Driver Surge Fault. The IH Driver detected surge. (Status code 0x3 is received)
Remedy: 1. Turn the power Off and On. If the error does not clear, continue to step 2. 2. Check the voltage and voltage variation at customer's outlet. If the problem was not resolved by turning the power Off then On and no problems were found after checking the voltage and voltage noise at the outlet, replace the IH Driver PWB.
