The problem is that after running more then 20 prints some of the words prints out very dark. only on three or four pages. I check the fuser it looked good. The transfer roller was replaced. they replaced the cartridge as well should I replaced the fuser anyway. It look like if you had printed in bold letting. I'm going back tomorrow to replaced the fuser, but if anyone has any thing else for me to try please let me know.
