Print Unable 68 Message – Brother MFC / DCP 9440, 9040, 9045, 9840

 

Troubleshooting Tips for the Print Unable 68 Message on the Brother 9440, 9040, 9045, 9840

The Print Unable 68 Message is a result of a high temperature reading on the side thermistor in the fusing assembly. Now it could be a genuine error code or a false one. Sometimes during sudden power outages the machine will read a false fuser error because the fusing unit temperature is being read at an improper time. Lots of times on these machines the fuser error has to be manually reset. Check the link below troubleshooting step 4 for instructions on how to reset. Large print jobs, heavy card stock, post cards, and envelopes can lead to higher than average fuser temps. If you are running jobs like these and experience this error then break the job up into smaller sections and allow time for cooling.

Troubleshooting Repair Tips for the Print Unable 68 Message

1. Check the environment and make sure the room temperature meets the machines specifications. I personally don’t recommend anything over 85 decrees. Make sure there is adequate space around the machine. I again, recommend 4 to 6 inch clearance on all sides.  Also, check the side vents and internal fans for blockage.

2. Turn the machine off and unplug from the wall outlet and let it sit 20 to 30 minutes to cool off.

3. Make sure the device is plugged straight into a wall outlet and the proper voltage is coming from it.

4. Perform manual reset in Maintenance Mode.

6. Replace the Power Supply Board.

6. Replace the Engine Control Board.
