Query: Good at first, downhill to VERY BAD!!!

At first, the printer seemed too good to believe. Fast, no jams, just perfect for lots of printing. Within 6 months, it started cranking out GREY PAGES. Like everyone else, I bought new toner but that didn't help. The grey pages obliterate any printing I try to do. A new drum costs at least $130. Be very careful of the reconditioned ones because they can hide the grey page problem for a short while but it's the drum that is bad. All in all, Brother took me for $250 and the new toner which is full but unusable. When someone posts on here after having a printer a week, you do everyone a disservice because you say great things without any experience to back it up. I WILL NEVER BUY ANOTHER BROTHER.
