• Code: 41.3
• Display: 41.3 LOAD TRAY XX <TYPE> <SIZE>
• Description: This is typically caused if two or more sheets of media stick together in the MFP or if the tray is not adjusted correctly.
• Remedy: 1. Make sure the correct settings are set for the trays. 2. Run a paper path diagnostic test to determine if all sensors are working correctly. 3. Replace the paper feed assembly.

• Code: 41.3
• Display: 41.3 LOAD TRAY XX <TYPE> <SIZE>
• Description: The specified tray is loaded with media that is longer or shorter in the feed direction than the size adjusted for the tray.
• Remedy: 1. Make sure the correct settings are set for the trays. 2. Run a paper path diagnostic test to determine if all sensors are working correctly. 3. Replace the paper feed assembly.

• Code: 41.5
• Display: 41.5 Unexpected Type In Tray <X>
• Description: The printer senses a different media type in the media path than configured in the tray.
• Remedy: 1. Make sure the correct settings are set for the trays. 2. Run a paper path diagnostic test to determine if all sensors are working correctly. 3. Replace the paper feed assembly.

• Code: 49.XXXXX
• Display: 49.XXXXX ERROR
• Description: A critical firmware error has occurred that caused the processor on the formatter to abort operation. This type of error can be caused by invalid print commands, corrupt data, or invalid operations. In some cases, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor-quality parallel cables, poor-connections, or home-grown programs. On rare occasions, the formatter is at fault.
• Remedy: 1. Turn the MFP off and then on. 2. Press Stop to clear the print job from the printer memory. 3. Turn the MFP off and then on. 4. Try printing a job from a different software program. If the job prints, go back to the first program and try printing a different file. If the message appears only with a certain software program or print job, contact the software vendor for assistance. 5. If the message persists with different software programs and print jobs, disconnect all of the cables to the printer that connect it to the network or computer. 6. Turn the MFP off. 7. Remove all memory DIMMs or thirdparty DIMMs from the printer. (Do not remove the firmware Compact Flash.) 8. Ensure that the formatter is securely seated. 9. Remove all EIO devices from the printer. 10. Turn the MFP on. 11. If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and on again as you install each device. 12. Replace a DIMM or EIO device if you determine that it causes the error. 13. Remember to reconnect all of the cables that connect the printer to the network or computer. 14. Upgrade formatter and DC controller firmware, which can be found in a single . 15. If the error persists, upgrade the firmware compact flash card. 16. Replace the formatter and calibrate the printer. NOTE: Formatter failures producing 49 errors are extremely rare. Formatter replacement is probably not required.

• Code: 50.X
• Display: 50.X FUSER ERROR
• Description: A fuser error has occurred. The following are specific fuser errors: 50.1: A low fuser temperature error has occurred in the main thermistor. 50.2: A fuser warmup service error has occurred. 50.3: A high fuser temperature error has occurred in the main thermistor. 50.6: An open fuser error has occurred. 50.7: A fuser pressure release mechanism failure has occurred. 50.8: Low fuser sub-thermistor temperature 50.9: High fuser sub-thermistor temperature The error might be due to an inadequate power supply, inadequate line voltage, or a problem with the fuser.
• Remedy: 1. Turn the MFP off and allow it to cool down. 2. Reinstall the fuser, and check the connector (J5001) that connects the fuser and the printer. Replace the connector if it is damaged. 3. Replace the fuser. 4. Check all cable connections to/from the DC controller. 5. Replace the low-voltage power supply PCB.

• Code: 51.1Y
• Display: 51.1Y Printer Error
• Description: A laser error has occurred. 51.10 = Black 51.11 = Cyan 51.12 = Magenta 51.13 =Yellow
• Remedy: 1. Turn the MFP off and then on. 2. If possible, run the scanner test diagnostic for the laser scanner indicated. 3. Reseat the connectors (J1002 - Y, J1003 - C, J1004 - M, J1005 - K) between the laser/scanner and DC controller PCB. 4. Upgrade formatter and DC controller firmware, which can be found in a single. 5. Replace the defective laser/scanner assembly. Calibrate the printer after replacing the laser/ scanner.

• Code: 51.2Y
• Display: 51.2Y Printer Error
• Description: A laser beam error has occurred. 51.20 = Black 51.21 = Cyan 51.22 = Magenta 51.23 = Yellow
• Remedy: 1. Turn the MFP off and then on. 2. If possible, run the scanner test diagnostic for the laser scanner indicated. 3. Upgrade formatter and DC controller firmware, which can be found in a single. 4. Reseat the connectors (J1002 - Y, J1003 - C, J1004 - M, J1005 - K) between the laser/scanner and DC controller PCB. 5. Replace the defective laser/scanner assembly. Calibrate the printer after replacing the laser/ scanner.

• Code: 52.XY
• Display: 52.XY ERROR
• Description: A printer error has occurred.
  X Description 00 = Scanner error 01 = Scanner startup error 02 = Scanner rotation error Y Description 0 = Black 1 = Cyan 2 = Magenta 3 = Yellow
• Remedy: 1. Turn the MFP off and then on. 2. Upgrade formatter and DC controller firmware, which can be found in a single . 3. Reseat the connectors between the laser/scanner and DC controller PCB. 4. Replace the defective laser/scanner assembly. Calibrate the printer after replacing the laser/ scanner.
