Question

I get a carrage jam error when i first start the printer. there are no jams and no print jobs processing. I hit OK and it pulls ALL the paper thru. Turning the printer off/on and doing a factory reset does not help. Is it a lost cause or can i open it up and try some things myself? I am capable of fixing certain things on printers but don't know how to open it up. Can u help?
Thanks,
