Hello,

I'm probably off topic (printer vs computer), but I need help. I am pretty sure the laser/scanner assembly on my Brother MFC 6800 needs cleaning (vertical white lines; have already changed toner and drum unit). I'm not afraid to open anything (almost), but any advice on where to attack (take off top, bottom, back , rt/left side) would be appreciated. Also, when I get to the laser and mirror(s), I assume I should use a q-tip and rubbing alcohol.

Of course, after cleaning I will assemble in reverse ORDER of disassembly, and save any left over parts.  

Happy New Year
David Bi only use good soft elk tips for my Q-Tip on my snooker cue. oh yeah and happy new year bro.I started this thing, and I want to end it. This thing is easy to FIX. Brother at 800-276-7746-1-5 said they serviced laser printers, not MFC laser printers, so they connected me to the MFC group at 800-284-4329 and they knew everything I needed to know, which is very little and also about equal to what I already knew.. I had apparently spilled a little toner on a glass strip under the drum unit. Th fix, pull the drum, wipe the 6" x 1/2" glass strip under where the drum was, and wo la, the vertical white lines are HISTORY, and I didn't even unsheath my #2 phillips. Thank God for tech support.
PS Cleaning the Corona wire is also recommended. There is a blue deal on the underside of the drum unit. SLIDE it back and forth about 7 times. THANKSI suspect you know more about your printer than anyone here.
Happy you have it fixed
