try to configure the fax receive mode to : fax only
WorkCentre M20i - Machine always waits until after 6 rings to answer on an incoming fax, regardless of the setting under "Ring To Answer" in the Fax Setup Options. Whether I have it set to 1 or 7, it rings 6 times on incoming faxes which leads me to believe that this setting is for outgoing faxes. How do I change the number of rings on incoming faxes?
