Is this a brand new drum from Brother or is it refilled? When you inserted the new drum/toner cartidge assembly into the printer and before closing the front cover you need to press the "Option" button. You should then see "Replace Drum?" appear on the LCD. Press the up arrow key which should result in "Accepted" being displayed on the LCD. If you didn't do this give it a try and you should be good to go. If your still stuck let us know otherwise please don't forget to rate the post.
