Distinctive Ring
The distinctive ring feature offered by your telephone service provider provides:
- The purchase of additional telephone numbers.
- Differentiation of these numbers by different distinctive ring rates, and thus
- The opportunity to have multiple phone numbers assigned to one physical telephone line.
- The ability for your MFP to be assigned to one of these phone numbers and its associated distinctive ring. For example, the ability for the MFP to pick up on a single, double, or triple ring, or any combination.
Note: There will most likely be an additional charge for this feature but it will be less expensive than having a dedicated phone line.
Warning—Potential Damage: All three ring settings (Single, Double, Triple) are turned ON by default on the MFP.
Turn off any distinctive ring patter n(setting) that is not dedicated for fax function. To do this, deselect any ring pattern that is intended for another device. But be certain about which ring pattern and phone number is intended for faxes; for example, double ring for the phone and a single ring for fax.

Receive Speed: Setting Locations
Faxing over Voice over Internet Protocol (VOIP) may require you to adjust speed settings for various reasons.
Change the setting to 9600 bps.
- If 9600 bps is successful, then try increasing the speed in increments up to 14.4 kbps.
- If 9600 bps is not successful, then consider topics under Other Suggestions or Main contributing factors to Fax Receive failure to go back to the main contributors to a fax receive failure.
Precautions
- Ensure consistent diagnosis by testing this setting only with the problematic sending fax machine.
- You can continue to increase the speed as long as successful fax transmissions persist.
- Higher fax speeds require a clean and strong analog signal, so increase speed with caution.

Other Settings: All MFPs
- Verify that ECM (Error Correction Mode) is enabled. This is an important setting for dropped faxes. Toggle this setting OFF and ON and test again.
- Turn ON the Speaker Setting which may be preventing you from hearing a possible distinctive ring pattern.
- Check the paper level as a lack of paper will prevent fax transmission.
- Make sure that the Fax Forwarding setting is not turned on (some models only).
- Understand that the X502 and X215 MFPs do not support distinctive ring.
- If MFP is competing with other phone devices, try to adjust the MFP # of rings as a countermeasure to give yourself more time to pick up the other device.
- Check Manual Fax settings. If manual fax is enabled, you will be required to perform specific steps necessary to receive the fax.

Firmware Update Information
Occasionally the MFP is the cause of the fax failure; however, this is rarely a physical hardware failure. If it is determined that a firmware update may alleviate this fax receive issue, it is important to consult a technical support representative to discuss other resolution paths and to perform additional diagnostic tests.
