Hi dijean71,
Before using the Distinctive Ring Pattern Detection (DRPD) option, a distinctive ring service must be installed on your telephone line by the telephone company. After the telephone company has provided a separate number for faxing with a distinctive ring pattern, configure the fax setup to monitor for that specific ring pattern.
To receive faxes in the DRPD, you need to set the menu to DRPD mode.
The printer provides seven DRPD patterns. If this service is available from your telephone company, ask your telephone company which pattern you need to select to use this service.
Please check and reply for further help.
