https://community.usa.canon.com/t5/Office-Printers/Canon-MF8500CDn-How-to-turn-on-Fax-sounds-when-sending/m-p/141809#M1828 <P>The MF8580Cdn has stopped providing fax send sounds, i.e. no dialtone sound, no touchtone sounds, no ringing, no "hiss" until paired. The machine does send&nbsp; faxes, it is just silent. It does "beep" after completion and produce a confirmation report. From all I can tell in the set-ups, all sounds are on and set at loudest volume (3). Other signals are present, so the speaker and amplifyer are working. There used to be sounds when faxing. Any suggestion for the proper settings? Thanks.</P> Tue, 26 May 2015 20:43:19 GMT HeavyDuty 2015-05-26T20:43:19Z https://community.usa.canon.com/t5/Office-Printers/Canon-MF8500CDn-How-to-turn-on-Fax-sounds-when-sending/m-p/141809#M1828 <P>The MF8580Cdn has stopped providing fax send sounds, i.e. no dialtone sound, no touchtone sounds, no ringing, no "hiss" until paired.
