Brother Intellifax 2800

1. Maybe a Paper Jam below the drum
2. A lever on the inner back cover is missplaced

Look at the front door that you open when you change the toner/drum. You will see that it has not closed properly at one end. Give it a gentle whack and the error should go. Very common problem as the catches can be stiff.

Open the top and back covers. If you see any jammed paper or
other item, gently pull it out, then close the covers. If the error message
remains, open and close the covers again. If the FAX/MFC cannot reset
itself and return to the date and time prompt, it will display MACHINE
ERROR XX. Please call Brother Customer Service

Open the drum cover and hold down CLEAR for 10 seconds.

Hope this is of some help.

hi,are you sure no paper jam ok check very very small paper in your machine or clean the sensor.

check the cover sensor arm if it still in place or check the cover hinge or lock if its still good.

It appears that you have a broken back door have a look on the door to see if there is a broken piece of plastic as when you shut the rear door a tab pushes against a push switch letting the machine know that the door is closed. if you cannot see a broken piece then the switch it faulty try this by push a flat screw driver on the switch and check if the message disappears.

Thanks J
