Description: Did not receive proper motor feedback to start laser servo. Motor connections
Remedy: 1 Main drive assembly (excessive noise or vibration) Remove the controller board and run a Diagnostic Print Test in the continuous mode. Check the main drive assembly for any excessive noise or vibration. Determine if the noise is in the main drive, toner cartridge, fuser, or main drive gearbox. Look for any loose or worn parts in the developer drive assembly, main drive gearbox, or fuser. Repair as necessary. 2 Main drive motor assembly (excessive noise, gears ratcheting and so on) A service error code 936 - Transport Motor may be displayed. Check the voltage at J20-6 on the system board. It measures approximately +5 V dc when the motor is not running and goes to 0 V dc when the motor is running. If incorrect, replace the system board. If this does not fix the problem, replace the main drive motor. 3 Main drive motor cable Check the continuity of the main drive motor cable. If incorrect, replace the cable. 4 Motor gear does not turn, no 936 error code or 201.xx Paper Jam user message displays. Check the voltages at J20 on the system board.

Code: 200.10
Description: Printhead motor not locked when page crosses input sensor • Printhead lock signal not working. • Printhead control not working
Remedy: • Check printhead to system card connections. • Check printhead motor system.
Code: 200.11
Description: Printhead motor fell out of lock after page arrives at input sensor • Paper pre-staged in path. • Lock signal went away.
Remedy: • Check printhead to system card connections. • Check printhead motor system.
Code: 200.13
Description: Input sensor covered during warm-up sequence. Page still covering input sensor.
Remedy: 1 Input sensor flag Check the input sensor flag for damage and proper operation. If a problem is found, repair as necessary. 2 System board Check for approximately +5 V dc at J15-10 on the system board. If incorrect, replace the system board. 3 Input sensor cable Check the continuity of the input sensor cable section of the front wiring harness. If incorrect, replace the harness. If correct, replace the input sensor assembly.
Code: 200.14
Description: Gap too small • Paper pre-staged in path. • Bouncy input sensor.
Remedy: • Check MFP mechanism and friction pad. • Fan media and stack flat in tray or MPF. • Use different media.
Code: 200.16
Description: Main drive motor error possibly due to mechanical load. Main drive motor not working. High mechanical load due to paper jam or bind.
Remedy: 1 Main drive assembly (excessive noise or vibration) Remove the controller board and run a Diagnostic Print Test in the continuous mode.
