User Manual for the Brother HL-228 doesn't seem to be helping in this regard. Also after two months of light use, I"m getting a "low toner" reading. I'm not happy. To be continued.
My wife cleaned the sensors with a damp washcloth and now the "No Paper" message is gone and printer works. However, even after shaking toner is low after mild use. Seems my old HP got a lot more mileage. But I am not buying a new printer.
