Question about HP 640 Inkjet Fax Machine

Phone works fax won't

I can call out on the telephone on the fax, but it won't send or receive. I just bought it last week, after the other one I had quit working. When I first set it up, it worked and now it is doing what the other one did. When someone tries to send me a fax, the phone just dings, not a regular ring, and the fax never comes. same problem - did you ever resolve?

Brother mfc-7840w won't receive fax


The first thing that I would try multiple people to ask them to fax you.Sometimes the 2 machines don't "sync".This is a toll free fax test number that I always use to check my machines..1-888-473-2963.Just write the words "FAX TEST" in large letters on a blank sheet of paper..fax it to that number...leave the line open...you should get a fax back in about a minute.If you get a fax back...your machine is fine...let me know if this was helpful....thanks.

I've been trying to send a fax to an office in Sri Lanka for several days now, but it won't go. We are getting a Comm Error 388 in the fax error report. The unusual thing is we are able to send fax...


inernational fax calls quite often do not work on digitized phone lines or via satellite. You cannot fix that. maybe your fax has a "fallback 4800 bps" setting that might be helpful.

We have the Brother Intellifax 4100E. It was working fine up until last week. Then it started not receiving faxes. We can copy, and send faxes, and receive the confirmation. I have checked the mode button...


Try calling the fax machine from your mobile and see if it picks up or if anything shows up on the screen of the fax machine. Is it possible that you have plugged the fax machine into the wrong telephone line? Try sending a fax to your mobile phone and see that the number is correct.

No dial tone on handset. can't send or recieve fax.


? Other equipment, which uses the same phone line as the HP All-in-One,
might be causing the test to fail. To find out if other equipment is causing a
problem, disconnect everything from the phone line, and then run the test
again. If the Dial Tone Detection Test passes without the other equipment,
then one or more pieces of the equipment is causing problems; try adding
them back one at a time and rerunning the test each time, until you identify
which piece of equipment is causing the problem.
? Try connecting a working phone and phone cord to the telephone wall jack
that you are using for the HP All-in-One and check for a dial tone. If you do
not hear a dial tone, contact your telephone company and have them check
the line.
? Make sure you have correctly connected the HP All-in-One to the telephone
wall jack. Using the phone cord supplied in the box with the HP All-in-One,
connect one end to your telephone wall jack, then connect the other end to
the port labeled 1-LINE on the back of the HP All-in-One.

If the supplied phone cord is not long enough, you can extend it. For
information, see The phone cord that came with my HP All-in-One is not long
enough.
Check the connection between the telephone wall jack and the HP All-in-One
to make sure the phone cord is secure.
Make sure you use the phone cord that came with the HP All-in-One. If you
do not use the supplied phone cord to connect from the telephone wall jack
to the HP All-in-One, you might not be able to send or receive faxes. After
you plug in the phone cord that came with the HP All-in-One, run the fax test
again.
If you are using a phone splitter, this can cause faxing problems. (A splitter is
a two-cord connector that plugs into a telephone wall jack.) Try removing the
splitter and connecting the HP All-in-One directly to the telephone wall jack.

If you are using a phone splitter, this can cause faxing problems. (A splitter is
a two-cord connector that plugs into a telephone wall jack.) Try removing the
splitter and connecting the HP All-in-One directly to the telephone wall jack.
If your telephone system is not using a standard dial tone, such as some
PBX systems, this might cause the test to fail. This will not cause a problem
sending or receiving faxes. Try sending or receiving a test fax.
Check to make sure the country/region setting is set appropriately for your
country/region. If the country/region setting is not set or is set incorrectly, the
test might fail and you might have problems sending and receiving faxes.
Make sure you connect the HP All-in-One to an analog phone line or you will
not be able to send or receive faxes. To check if your phone line is digital,
connect a regular analog phone to the line and listen for a dial tone. If you do
not hear a normal sounding dial tone, it might be a phone line set up for
digital phones. Connect the HP All-in-One to an analog phone line and try
sending or receiving a fax.
Make sure you use the phone cord that came with the HP All-in-One. If you
do not use the supplied phone cord to connect from the telephone wall jack
to the HP All-in-One, you might not be able to send or receive faxes. After
you plug in the phone cord that came with the HP All-in-One, run the fax test
again.
After you resolve any problems found, run the fax test again to make sure it
passes and the HP All-in-One is ready for faxing. If the Dial Tone Detection test
continues to fail, contact your telephone company and have them check the
phone line.

Canon 1023if not receiving faxes automatically


Is this fax line shared with the phone? I believe there is a distictive ring setting in the add'l functions area under communication settings then receive settings. you would need to select a ring pattern different so the fax can tell between which types of calls it is receiving.

It has worked for me in serveral other installs

Hope this helps

Can receive a fax, but cannot send fax.


I was told by Xerox support tech that he thought it was the fact that we do not have a dedicated analog phone line, but the fact remains we can receive faxes but cannot send them. The only fax that will send is directly to Xerox support.???. The machine was working fine, faxing (sending and receiving), until about a week or so ago, when we had a repairman here on the printer. He told me to report the problem to our telephone repair service. He is coming out today! I'll let you know.
