Question about Brother MFC-9420CN All-In-One Laser Printer
Machine says unable to print, see troubleshooting and routine maintenance. Nothing works to fix it. Went into service mode and gave machine error 28. What does that mean?
Well it's a low temp error for the fusing assembly. Sounds like you already had it in Maintenance Mode. Sometimes those errors can only be cleared out by entering maintenance mode and pressing 9,9 to exit out. Should then start the normal warm up procedure. If the problem continues then reseat the fuser or take it out and measure for continuity across the lamp and thermostat. The service manual also recommends checking the line voltage. Basically make sure it's plugged straight into a wall outlet and no other large power sources on the same circuit. Example, another copier or this time of the year a small space heater.
Maintenance Mode enterance Press Menu/Set and Black start button and Up arrow 4 times. Machine will read Maintenance on the display if done correctly. Press 9,9 to exit of the mode and the machine will attempt to restart normally.
