• Code: 2000
• Description: Main drive motor lock
  • The frequency generation pulse which the main drive motor generates to CPU (U2) on the engine controller PWB (KP-992) in normal operation (after self-diagnostics codes 2010 and 2020 are cleared) is not at the correct frequency.
• Causes: Defective main drive motor. Excessive torque for driving drum unit or primary transfer unit. (Overloaded by a damaged gear.) Defective harness (2CK2711) between engine controller PWB (KP-992) and main drive motor, or poor contact of the connector terminals. Defective engine controller PWB (KP-992).
• Remedy: 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 (2CK2711). Check the insertion of connectors. Replace the engine controller PWB (KP- 992).

• Code: 2010
• Description: Main drive motor starting error
  • No FG (Frequency generation) pulse is entered within the predetermined period since ASIC (U8) on the engine controller PWB (KP-992) has issued a motor activation signal to the main drive motor.
• Causes: Defective engine controller PWB (KP-992). Defective main drive motor. Excessive torque for driving drum unit or primary transfer unit. (Overloaded by a damaged gear.) Defective harness (2CK2711) between engine controller PWB (KP-992) and main drive motor, or poor contact of the connector terminals. Defective engine controller PWB (KP-992).
• Remedy: Replace the engine controller PWB (KP- 992). 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 (2CK2711). Check the insertion of connectors. Replace the engine controller PWB (KP- 992).

• Code: 2020
• 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 PWB (KP-992) has issued a motor activation signal to the main drive motor.r.
• Causes: Defective main drive motor. Excessive torque for driving drum unit or primary transfer unit. (Overloaded by a damaged gear.) Defective harness (2CK2711) between engine controller PWB (KP-992) and main drive motor, or poor contact of the connector terminals.
• Remedy: 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 (2CK2711). Check the insertion of connectors.

• Code: 2101
• 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 PWB (KP-992) during normal operation (after selfdiagnostics codes 2111 and 2121 are cleared).
