NUMBER OF RINGS TO ANSWER FAX

There is excellent support here on basic fax setups. You have what is known as "Distinctive Ringing Service". There are pros and cons to the various setups. I assume you recognize the rings and answer only when the ring for the landline talk comes on. The fax will pick up the faxes, and the answering machine will pick up the voice.

Distinctive Ringing Service setup While it is not available everywhere, a distinctive ringing service can be purchased from most telephone companies. With this service, more than one phone number is assigned to the same phone line. Each phone number will ring differently. The main number will ring with a normal single ring and the additional number will ring with a distinctive ring pattern assigned by the phone company.
When a distinctive ringing service is used, set the Rings to Answer to 2 and then follow the steps below to set the distinctive ringing pattern:

1. Press Setup , press 4 , and then press 1 to enter the Answer Ring Pattern setup of the Advanced Fax settings.
2. Use the Right Arrow to scroll through the available settings. When the ring pattern assigned by the phone company displays (double or triple rings), press OK .

Additional info:If you have an answering on the same line as your fax:

To make sure the printer picks up incoming faxes, set Auto Answer to On, and then set the printer to pick up after a greater number of rings than the answering machine. For example, if the answering machine picks up calls after four rings, then set the printer to pick up after six rings. This way, the answering machine picks up calls first and your voice calls are received. If the call is a fax, then the printer detects the fax signal on the line and takes over the call.

If you have a voicemail feature associated in the same line as your fax:

Voice mail and fax can share the same telephone line if you subscribe to a distinctive ring service offered by your telephone company. This feature allows you to have multiple telephone numbers on one telephone line. Each telephone number has a designated ring pattern (single ring, double ring, triple ring, or double and triple ring). The different ring patterns let you know which telephone number was dialed, and which device you should use to answer the call.

If you do not have distinctive ring service, then set the printer to receive faxes manually (Auto Answer Off). This setting lets you receive both voice calls and fax calls, but works best if you use voice mail more often. You need to turn off voice mail whenever you are expecting a fax.

When you set your fax machine to answer on a certain number of rings it will answer it on that number of rings expecting it to be another fax machine. If you do not answer it before the aloted number of rings you will not be able to talk since the fax machine will be trying to talk in computer speak. To help you may want to set it to answer after more rings.
