i have brother mfc 8860dn and every 10-20 pages a piece of paper gets jammed in the drum unit. It is easy to clear, but I do big jobs, and have to count the number of copies each time etc Please help The problem started when i put original brother drum unit in. [Had no paper jam problem with generic, but quality not good, (probably because i didn't know then how to install new drum kit and machine never recognised it)] vivien vshih8@gmail.com (preferred) or vshih@swiftdsl.com.au
