Printing Problem

I have the Brother MFC 7840W. When printing a page or even copying another page, I get the first few lines duplicated down the page on the printed copy. It gets lighter as it proceed down the page. I have changed the Toner cartridge several times without success and I changed the drum unit without success. Wondering if the fuser unit could be bad? or does anyone have any ideas? Thanks
