ECP + EPP is fine.
Are you using a driver disk from the mfr, or d/l'd from the internet. If from a disk, could be bad media. Try d/l'ing from the mfr's website.
If you're already using from the mfr's website, make sure you got the correct ones and maybe try d/l'ing again.
EDIT - Clicking "I Agree - Begin Download"
here should start the d/l of the 2K drivers for the BJC5000.
