I have a previous model DCPL2550DW and it has the low-toner warning too. Can't remember if it refused to print because I just went and bought a new toner for $45 which is cheap IMO. Anyways, I was perusing the Amazon reviews for my printer and came across this... maybe it'll help you? Now, to override the alert Brother gives you when it THINKS you are out of ink, I have user Allegra to thank for that as follows: "Go to the buttons and follow these instructions: MENU > GENERAL SETTINGS Press the down button (minus sign) until you get to REPLACE TONER Hit OK Please the down button (minus sign) until you see CONTINUE Hit OK
