HP CLJ 2840 fax comm errors

Have replaced the formatter/fax card assembly on this unit just recently for comm errors. Problem has resurfaced. ECM is off, fax speed is as slow as can make it. Still errors. Any ideas for fixing this would be appreciated. Errors are 232, 283, 284 so far. Doesn't seem to matter who's sending. Cheap old Brother ribbon type fax beside it doesn't seem to have any problems. They are using it as a backup.
What phone system do you have? Try to have a dedicated analog fax line. Is the country code correct? Correct line input? Not phone jack.
