My HP printer 6968 will no longer send faxes

[Jeff-NF]

My HP officejet pro 6968 says fax failure when I go to send a fax. The phone line works. I always used to send faxes from this machine, but haven't used the fax feature in a while.

Welcome to the HP Community Forum.

Fax is one of the most thoroughly documented features --

Nothing has changed in "the world of fax" for a while - old technology and still used world-wide.

If the HP test line service is still available, send a Test Fax.

What if

Voice transmission is so much more forgiving than is data transmission.  A noisy, old, damaged phone line - weather beaten, squirrel chewed, and generally "hanging in there" might still work as a voice call phone line.  The same line might not carry fax data, resulting in failed faxes either sending or receiving.  True -- ECM can be turned off / on and fax speed can be changed -- and at some point, what you can do from the outside might not be enough. 

When everything else is eliminated, including trying a different 2-wire phone cord, trying a different phone wall connection, moving the printer, plugging the printer into a different wall outlet, testing, poking, checking, and configuring the setup from scratch -- 

then

Consider that the failure might be hardware.

Try / Consider

Phone companies typically do not care whether your voice phone line can fax / carry data. 

Certainly worth asking your phone company for help -- not all phone companies are equal.

If you use the same phone line for both fax and voice -

Possible solution:  Go under the house and rewire the phone line to the connection just outside the house.

Another time, we lost our phone service -- the phone company fixed that connection (break was actually down the road), which also fixed our service and the fax.
