I am hoping for some help. I am just about ready to look for another printer, but I cannot help but think the problem is minor and I just can't figure it out. Love the printer. Had it for about 1 1/2 years. Prints one sided fine. When I do 2 sided printing, odd pages are missing most of print. Can see a very light image. Bottom of page is OK, started around 20% bad or missing, now about 80% bad, light, or missing. All on top of page. I called Brother and none of their suggestions helped. I have cleaned all contacts, cleaned drum, removed and cleaned fuser, replaced toner. Now I am stuck. I am confused because if I am printing, let's say 8 pages, 2 sided, 2,4,6,8, print fine. 1,3,5,7 are crap. HELP !!
