Code :

Code: C2020
Description: Main drive motor starting time-out • The FG (Frequency generation) pulse does not reach the correct frequency since ASIC (U8) on the engine controller PCB has issued a motor activation signal to the main drive motor.
Causes: Defective engine controller PCB. Defective main drive motor. Excessive torque for driving drum unit or primary transfer unit. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and main drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the main drive motor. Check if the drum unit or primary transfer unit rotates smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2101
Description: Black developer drive motor lock • The FG (Frequency generation) pulse which the black developer drive motor generates is not entered at the correct frequency in CPU (U2) on the engine controller PCB during normal operation (after self-diagnostics codes 2111 and 2121 are cleared).
Causes: Defective engine controller PCB. Defective black developer drive motor. Excessive torque for driving black developer. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and black developer drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the black developer drive motor. Check if the black developer rotates smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2102
Description: Color developers drive motor lock • The FG (Frequency generation) pulse which the color developers drive motor generates is not entered at the correct frequency in ASIC (U8) on the engine controller PCB during normal operation (after self-diagnostics codes 2112 and 2122 are cleared).
Causes: Defective engine controller PCB. Defective color developers drive motor. Excessive torque for driving color developers. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and color developers drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the color developers drive motor. Check if the yellow, magenta, and cyan developers rotate smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2111
Description: Contents Black developer drive motor starting error • No FG (Frequency generation) pulse is entered when ASIC (U7) on the engine controller PCB has issued a motor activation signal to the black developer drive motor.
Causes: Defective engine controller PCB. Defective black developer drive motor. Excessive torque for driving black developer. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and main drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the black developer drive motor. Check if the black developer rotates smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2112
Description: Color developers drive motor starting error • No FG (Frequency generation) pulse is entered when ASIC (U7) on the engine controller PCB has issued a motor activation signal to the drive motor for the color developers.
Causes: Defective engine controller PCB. Defective color developers drive motor. Excessive torque for driving color developers. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and color developers drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the color developers drive motor. Check if the yellow, magenta, and cyan developers rotate smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2121
Description: Black developer drive motor starting time-out • The FG (Frequency generation) pulse does not reach the correct frequency when ASIC (U7) on the engine controller PCB has issued a motor activation signal to the black developer drive motor.
Causes: Defective engine controller PCB. Defective black developer drive motor. Excessive torque for driving black developer. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and main drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the black developer drive motor. Check if the black developer rotates smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2122
Description: Color developers drive motor starting time-out • The FG (Frequency generation) pulse does not reach the correct frequency when ASIC (U8) on the engine controller PCB has issued a motor activation signal to the drive motor that drives the color developers.
Causes: Defective engine controller PCB. Defective color developers drive motor. Excessive torque for driving color developers. (Overloaded by a damaged gear.) Defective harness between engine controller PCB and color developers drive motor, or poor contact of the connector terminals.
Remedy: Replace the engine controller PCB and check for correct operation. Replace the color developers drive motor. Check if the yellow, magenta, and cyan developers rotate smoothly. Check for broken gears. Replace if any. Check the continuity of the harness and the insertion of connectors.

Code: C2340
Description: Fuser drive motor driving clock table error • An error has occurred in the driving clock table on the engine controller PCB that controls the fuser drive motor (a stepping motor).
Causes: Defective engine controller PCB.
Remedy: Replace the engine controller PCB and check for correct operation.
