How to fix Brother HL-2250DN that cannot make print through duplex-printing?
- EEric AndersonSep 18, 2025
If your Brother printer is unable to perform duplex printing, start by checking the harness connection of the paper eject sensor PCB ASSY and reconnect it if necessary. The duplex tray itself might be faulty and need replacing. The back cover sensor could also be the cause, requiring replacement of the paper eject sensor PCB ASSY. In some instances, the main PCB might be the issue, necessitating replacement. Damaged DX gears could also prevent duplex printing, requiring replacement of the main frame L ASSY.
