Description: Developer unit motor-YMC locking error: The developer unit motor-YMC is not rotating normally.
Remedy: (1) Pull out the EPU tray and perform the output check (03-113) to check if the 3 outputs of the YMCdeveloper roller and 3 outputs of the drum cleaner auger are rotating normally. When it is not rotating (2) Check if the connector of the YMC-developer unit motor is connected securely. (3) Check if the harness or connector of the drum motor (K)/(YMC) is disconnected or opencircuited. (4) Check if the YMC-developer unit motor is abnormal. (5) Check if the column of the drive gears has any abnormality such as damage. When it is rotating (6) Check if waste toner is clogged on the waste toner transport path of the YMC-drum cleaner. (7) Check if the developer material is excessively supplied to each YMC-developer unit. (8) Check if the drive gear array of each YMC-developer unit has any abnormality such as breakage.

Description: Developer unit mixer motor-YMC locking error: The developer unit mixer motor-YMC is not rotating normally
Remedy: (1) Pull out the EPU tray and perform the output check (03-115) to check if the 3 outputs of the YMCdeveloper unit mixer are rotating normally. When it is not rotating (2) Is the connector of the YMC-developer unit mixer motor connected securely? (3) Check if the harness or connector of the YMC-drum motor is disconnected or open-circuited. (4) Check if the YMC-developer unit mixer motor is abnormal. (5) Check if the drive gear array has any abnormality such as breakage. When it is rotating (6) Check if developer material is excessively supplied to each YMC-developer unit. (7) Check if the drive gear array of each YMC-developer unit has any abnormality such as breakage.

Description: Developer unit motor-K locking error: The developer unit motor-K is not rotating normally.
Remedy: (1) Pull out the EPU tray and perform the output check (03-113) to check if the 3 outputs of the Kdeveloper roller and 3 outputs of the drum cleaner auger are rotating normally. When it is not rotating (2) Is the connector of the K-developer unit motor connected securely? (3) Check if the connector of the K-developer motor is disconnected or the harnesses are open circuited. (4) Check if the K-developer unit motor is abnormal. (5) Check if the drive gear array has any abnormality such as breakage. When it is rotating (6) Check if waste toner is clogged on the waste toner transport path of the K-drum cleaner. (7) Check if the developer material is excessively supplied to the K-developer unit. (8) Check if the drive gear array of the K-developer unit has any abnormality such as breakage.

Description: 1st drawer tray abnormality: The tray-up motor is not rotating or the 1st drawer tray is not moving normally. (the case that paper can be fed from any drawer except the 1st drawer)
Remedy: Does the tray go up? (Perform the output check: 03-246, 247) NO 1. Check if the connector of the tray-up motor is disconnected. 2. Check if the connector CN508 on the PFC board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are open circuited. 4. Check if the conductor pattern on the PFC board is short circuited or open circuited. 5. Replace the tray-up motor. 6. Replace the PFC board. YES Is the tray-up sensor working? (Perform the input check: 03-[Copy ON]/[9]/[H], /[9]/[G]) NO 1. Check if the connector of the sensor is disconnected. 2. Check if the connector CN513 on the PFC board is disconnected. 3. Check if the slit reaches the sensor. 4. Check if the connector pins are disconnected or the harnesses are open circuited. 5. Check if the conductor pattern on the PFC board is short circuited or open circuited. 6. Replace the tray-up sensor. 7. Replace the PFC board. YES 1. Check if the conductor pattern on the PFC board is short circuited or open circuited. 2. Replace the PFC board.
