Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks

I have a Brother MFC-8480 DN all in one printer, copier, fax and scanner.
I discovered that envelopes wrinkle because users, like me, didn't know that Brothers built in a no-wrinkle, pass through exit for envelopes, labels and thick paper.
Envelopes were never to be printed by inserting them in the front and letting them wrap around a HOT roller and get cooked and wrinkled. The way it works:
An envelope is inserted in the front and goes straight out the back of the printer through an exit door, completely avoiding the hot roll-through mechanism.
Take a look. On the back of the machine is a large pass through exit door. Just snap it open. You will see one blue lever on each side of the opening. Snap them both straight down to the . . .ta da. . ."envelope icons".
Put three envelopes in the front and they will print straight out the back, perfect and wrinkle free. After printing your envelopes, snap the blue levers back up and shut the door. Takes about five seconds to open the door and snap down the blue levers down/up.
Happy envelope printing.

This usually works.

Usually caused by a sticking density sensor solenoid and can easily be repaired.
Remove the rear cover
Remove the fuser
Remove the Hi Voltage PCB
Check the angled density sensor window for sticking. When you move it, it should spring right back. If it hesitates at all, repair the solenoid.
Remove the old foam and replace it with adhesive labels.
Reassemble machine and test.
