What to do if the Alarm lamp is flashing on my Brother HL-4200CN?

If the Alarm lamp is flashing on your Brother Printer, a problem that the user cannot rectify has occurred. Note the error code on the display, turn the printer off immediately, disconnect the power cord from the outlet/socket, and contact your dealer or Brother Customer Service.
