Why does my Brother HL-2240 only print on one side when duplex printing?
- PPaul LewisSep 1, 2025
If your Brother printer is only printing on one side of the paper when duplex printing, consider these potential causes: * Check the harness connection of the paper eject sensor PCB assembly and reconnect it if necessary. * The duplex tray might be faulty and need replacement. * The back cover sensor might be failing, requiring replacement of the paper eject sensor PCB assembly. * The main PCB might also be the cause, requiring replacement. * Damaged DX gears could also be the issue, requiring replacement of the main frame L assembly.
