Question about Brother MFC-8440 All-In-One Laser Printer
Is there a sensor on the cover? the cover in my mfc-8440 displey doc cover open but its close.
Yes there is and I know your problem have a look at the left hinge on lid that you lift to put down an original for copying, it will be breaking apart, the switch is black in that same corner on doc feeder base, as the hinge breaks apart the doc feed lifts in that corner causing "doc cover open" cause that switch no longer gets pushed in when lid is shut
Dodgy repair - tape switch closed, but doc feeder will not work properly/can use glass.
Repair - Easy removal of three screws and replacing 20buck hinge bought from brother dealer...part no.LE8731001 Hinge assy left.
Now that's FIXYA!

Tips for a great answer:
Brother Laser Printers:
After replacing the drum unit, keep the front cover open (make sure the power is on). Press and hold the "GO" button until all four LED's are lit. Once the four LED's light up, close the front cover. Make sure the drum LED is off. The counter is reset!
Brother Fax Machines:
Open the front cover. Press the CLEAR/BACK button. Press 1, when the display shows accepted.
