What to do if my Brother HL-2270DW cannot detect toner?
- JJohn WilsonAug 27, 2025
If your Brother printer can't detect the toner, it might be due to these reasons: * If the power was turned off or the front cover was opened while detecting a new toner cartridge, reset the developing bias voltage and develop roller counter. * If the new toner actuator is loose, re-assemble it. * If the new toner sensor has failed, replace the panel PCB assembly.
