SOURCE: ERR UN FUSAO CRU - SCX 4521F
Eu tive o mesmo erro, e foi quando eu troquei o cartucho de toner. Deve ser um problema no fusível do cartucho, porque quando retirei o fusível e deixei sem o mesmo, a impressora voltou a funcionar normalmente. Agora estou providenciando um fusível novo para substituir.

open heat error sounds like the fuser lamp is blown. The fuser lamp is inside the hot roller at the back which melts the toner onto the page. It is not really a user serviceable part, you would need someone qualified to repair/replace the fuser.

As Roipatrick said, for Paper Jam 1 the location of the Jam is In the fuser area or around the toner cartridge. I download the service manual from www.elektroda.pl/rtvforum/download.php?id=362035 and it suggested:
1. If the recording paper is jammed in front of or inside
the fuser. -> 1. Replace the SMPS.
2. If the recording paper is stuck in the discharge roller
and the fuser just after passing through the Actuator-
Feed, Feed Actuator may be defective. ->
2. Reassemble the Actuator-Feed and Spring-Actuator
if the returning is bad.
I found if I push the paper a little bit when it goes in, it can print, so I conclude neither is correct, it is pick-up sponge needs to be replaced. It will cost about $15 parts + shipping from http://www.partstore.com/Part/Samsung/Samsung/SCX4521F/Samsung/Samsung/JC7300211A/New.aspx
So I tight a rubber bend around the roller as showed in the picture and I am printing now. :-)
