Question : Problem: Brother prints dirty: how to clean him up?

After a trans-ocean move, my Brother HL-630 is adding dirty streaks to everything it prints.  If I ever had a manual for it, it's long gone and the Brother website doesn't post product manuals, so I took out the take-outable parts and wiped them clean, as well as wiping the drum as best I could through the slot, but it's not much better.  This must be very easy to solve, please help me solve it.

always suspect DRUM leakage in laser for this problem.  replace drum and correct the problem... HOWEVER _ most drum replacements now a days is not very cost effective.  check out the price of drums and compare to the price of newer models.. most of the times newer compatible model are better cost in the labor and cleaning fees associated with drum replacements.  And sometimes Cleaning and drum replacement will only be a quick fix for a declining printer
