Cannot send faxes when using cable company's digital voice modem

Hi Janet
Try using a standard phone to call your Fax Line
Connect a phone to this Line to test for voice
Disconnect Fax Machine from Phone Line
Reset Fax machine
The Fax machine is supposed to respond to the right tones being sent down the voice line
If it is not responding & all else works then check your Fax settings for "Receiving"

Try resetting the machine to it's defualt settings.

Make sure the phone line from the wall is plugged into the "line in" jack on your machine

Your modem setting probably is not compabile with the data rate your phone will support.

From the user manual --

If you are having difficulty sending or
receiving a fax due to possible interference
on the phone line, we recommend that you
adjust the compatibility setting to reduce the
modem speed for fax operation

Press a or b to choose Basic or
Normal (or High).
Basic cuts the modem speed to
9600 bps. Unless interference is a
recurring problem on your phone
line, you may prefer to use it only
when needed.
Normal sets the modem speed at
14400 bps.
High sets the modem speed at
33600 bps.
Press OK.
Press Stop/Exit.

The other thing to consider is do you have tone or pulse dial service from your telephone company?

The fax will only work on an analog phone line, most offices these days especially if you have multiple lines, are digital. You may need the phone company to install a modem compatible phone line.

Check the physical connection of the phone line to the computer make sure that it is connected to phone line symbol of the Ethernet adapter. Then make sure that the driver of the adapter is installed properly on the computer or you can try to scan the hardware first before the re-installation of the driver using the adapter.

I must tell you that this is not a printer issue, since printer does not have inbuilt fax capabilities....Actually you are trying to send fax from the computer using a Data Fax Modem. Printer just used for scanning and printing documents for fax...

1. Please check if your computer have Fax modem.
Look at the back of the system tower, if you see a phone jack port (probably two of them).

2. If yes then , you need to have a telephone cable directly from wall (not the ethernet cable coming from DSL modem), fax works on analog signals which is possible only from telehone line.

If your phone line is working, there is no chance the it will give you error again for NO Dial tone

Hi,

Thanks for the additional info.

First of all, if you live in any of the following countries, you must make sure that you use the 2-wire phone cable that came with the printer instead of standard phone cable:

Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Greece,
India, Indonesia, Ireland, Japan, Korea, Latin America, Malaysia, Mexico,
Philippines, Poland, Portugal, Russia, Saudi Arabia, Singapore, Spain,
Taiwan, Thailand, USA, Venezuela, and Vietnam.

Secondly, I would strongly suggest that you download the latest copy of the users manual for your machine from the link below. Make sure that your connections are the same as those in the manual. There are also troubleshooting steps that are simply explained in the back of the manual:

The next thing to be sure of is that there is a dial tone at the phone that is built into your fax machine. If you are on a VOIP system (in other words, if your phone service comes into your home via your cable TV line or the cable company provides your phone service), then the cable modem/router must be configured to provide a dial tone to the outlet the fax machine is plugged into. To test if a dial tone is present, simply follow the normal fax procedures (they are also in the manual). When you tell the machine to fax, you should hear a dial tone just before your hear the tones of the fax number being dialed. If you don't, then your problem is with the cable company.

Sorry for the long-winded answer. Please let me know if this helps!

If the fax is seldom used, the conditioning of the line could be different or the modem damaged.

Pick up the phone on the unit and see if you can hear a dial-tone, commonly when surges come in through the phone lines and damage the modem component of the printer it can cause this issue and trying to place a call from the device can be a good test.

However, if you can hear the dial-tone using the phone and can call out on your device, it is probably not the modem and is related instead to the line itself.

If your on a company network or have DSL at home remember that faxes typically need dedicated analog lines and that DSL service, IP phones, or digital phone systems will often cause the modem to malfunction.
