Hp 8100

[slim]

I have problem with my HP 8100. I just changed the maintenance kits and did the cleaning on my HP 8100. After that, when I tried to print, all the pages went blur and the top part went blank. I thought the toner cartridge was bad, so I changed it. But it still does the same thing. What do you think the problem is?
I also have problem with paper jam eventhough I have changed the rollers.
Please helppppppp........... :confused:

Make sure the transfer roller is seated properly, also that the fuser is seated properly (http://www.printertechs.com/tech/mkinst/mk-5si8000-2fuser.php) and the pressure tabs down.
