Ricoh 4420
I'm working on a ricoh 4420 and I put this in place of a brother 4100.... There are some numbers when dialed fax to a different number...it will come up on the screen as communicating to a different number than dialed...this didnt happen on the brother 4100, and i put the brother back online and it works perfectly...it only happens on the Ricoh...Gotta be a setting...maybe ECM???havent tried yet...
