We have a Xerox® AltaLink B8045 that is receiving faxes printed on both sides (all faxes being received). We've gone into the machine interface and it shows 1-sided. We've gone into the web interface and it too is 1sided. We recently a had a IC board replaced and that's when the problem started.
It can't show 1-sided in the Fax receive defaults, only the send, but if it shows 2-sided as being disabled, then have the tech who replaced the board come back out and altboot the device.

Thanks Joe. Our service guy came out and tried several techniques (not an altboot) without success. He then called his Xerox tech connection with no luck there. Will come back next week and do an altboot.
