• 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. 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. J20-11 +24 V dc J20-8 +5 V dc 0 V dc J20-7 +5 V dc 0 V dc J20-6 +5 V dc +2.5 V dc J20-5 +5 V dc 0 V dc J20-4 +5 V dc +5 V dc J20-1 +5 V dc 0 V dc If the voltage is incorrect, replace the FRUs in the following order: • Main drive motor assembly • System board

• Code: 200.32
• Description: Detected cover switch bounce. • Upper cover not fully closed. • Cover switch not functioning correctly.
• Remedy: 1 Toner cartridge Make sure the toner cartridge is correctly installed and that the right and left cartridge tracks are not loose or broken. Make sure the cover closed switch activation tab on the toner cartridge is not broken and that the tab correctly activates the cover closed switch spring. 2 Cover closed switch/cable assembly Check the cover closed switch for proper mechanical operation. If incorrect, repair as necessary. Disconnect the cover closed switch cable from J8 at the system board and measure the voltage at J8-3. It measures approximately +5 V dc. If the voltage is incorrect, replace the system board. If the voltage is correct, check the voltage at J8-1. If the voltage measures greater than +1.0 V dc, replace the system board. If the voltage is correct, check the continuity between J8-1 and J8-3 on the cable. If no change in continuity occurs as the switch is activated, replace the hinge assembly. If the continuity changes as the switch is activated, replace the system board.

• Code: 201.00
• Description: Page did not reach exit sensor. Fuser page count between 0 and 99,999. • Page jammed on fuser input guide. • Page did not enter or exit fuser nip cleanly. • Exit sensor not functioning correctly.
• Remedy: • Check fuser entry guide for toner build up. • Check fuser for wear or contamination. If problem is found, replace the fuser assembly. See “Fuser assembly removal”. • The fuser exit sensor may not be functioning properly.

• Code: 30.xx
• Description: Invalid refill, change cartridge
• Remedy: The MFP detects a refilled Lexmark Cartridge Return Program print cartridge. Install a new print cartridge to clear the message.

• Code: 31.00
• Description: Defective cartridge
• Remedy: • Smart chip cabling loose on controller card. Reseat smart chip cabling inside printer. • Replace cartridge.
