Note: If you have subscribed to a voice mail service on the same phone line used for faxing, you will have to receive faxes manually. Check the printer fax settings •• The Auto Answer feature is turned on for the printer to receive fax automatically. •• If you have a telephone answering machine service from the phone company or service provider, ensure that the Rings to Answer on the printer is set to be more than that of the telephone answering machine. The printer will monitor the line and decide if an incoming call is a normal phone call or fax call. If it is a fax call, the printer will start a fax connection automatically. Otherwise, you might have to receive the fax manually by selecting Fax on the printer display. •• If multiple phone numbers are assigned to the same physical phone line and the line is shared by multiple devices, ensure that the printer is set to the correct distinctive ring setting for receiving faxes. Check the physical fax connections •• Connect the phone cord from the 1-LINE port on the back of the printer to the phone wall jack and connect a phone cord from the 2-EXT port on the back of the printer to an extension phone. From the extension phone, call the phone number that failed to receive the faxes. •• If you were trying to fax to an external number, be sure to include any required access code or numbers prior to entering the number. You might also need to add a pause in the number to prevent the printer from dialing too fast; to add a pause, press * repeatedly until a dash (-) appears on the display. •• If you cannot make any outgoing calls because no dial tone is detected or the line is noisy, try using another phone cord in place of the one connected to the 1-LINE phone port, or move the printer to another location which has a separate phone line (if possible) and see if there are similar problems. •• If you are in a digital phone environment (such as fax on VoIP), reduce the fax speed and turn off the Error Code Modulation (ECM) from the printer control panel. If needed, contact your phone company to find out if there are problems with the phone line or to learn more about the capabilities of the phone network. 19
