Fax which type of phone cord to use to connect my fax machine?

Dear
For any RJ !! type cable/cord may be used and connect to the printer where marked LINE.
Thanks.

The fax machine should have two places on the back where you can plug in a phone cord. One of these is the input: where the cord from the wall goes, and should have either "in" or a picture of a wall phone outlet next to it. The other is used as a line through the fax machine and should have a picture of a phone or "out" next to it. Ideally, you would plug the fax machine directly into the wall and then your phone/answering machine into the "out" plug on your fax machine.

When in auto mode, the fax machine will listen in on the line when the phone rings and if it detects a fax signal (all the whirring and beeping) it will pick up the phone and receive. If there is no signal, it will simply allow the signal to pass through to the phone and answering machine.

Instructions

1. Check the phone line connected to your fax machine for problems. This is one of the most common reasons fax machines don't work. Connect the phone line to a regular telephone and listen for a dial tone. If you don't have a dial tone, replace the phone cord to see if that was the problem. If that isn't the problem, test the other phone lines in the office. If the other lines aren't working, contact your phone provider to have them fix the phone line.
   
2. Look at the electrical cord of your fax machine if the unit won't power on or work at all. Check that the cord is properly plugged into the wall and into the back of your fax machine. If it is, and it still isn't working, replace the cord.
   
3. Inspect the lamp on your fax machine to see if it is working properly. Fax machines may receive faxes, but not send them if the bulb is burned out.
   
4. Open the cover to your fax machine if you are getting complaints that your fax machine isn't sending quality faxes. Do this by pulling on the front panel of the unit. Using a soft cloth, clean out the dust and debris from this front panel. Accumulation of dirt here could definitely be the problem.
   
5. Watch for any toner or ink splotches on the inside of your fax machine. If your copies or faxes aren't printing at a high quality, you may have an ink problem. When you shake your toner cartridge, it should shake cleanly and no toner should leak out. If you have a leaky cartridge, it is bad.

The flat cord is the USB for your computer, the phone cord plugs into your telephone.

Only if you have fax software on your computer and scan an image to the computer to fax, otherwise you need a really long phone cable you can buy at Radio Shack or Best Buy.

The black curly cord goes from the phone receiver (handset) to the first jack on the left side of the fax (the one closest to the handset that's marked with a phone symbol). The flat grey cord is the phone cord. It connects the wall jack to the fax machine's third jack (the one closest to the back of the machine that's marked with the word "LINE").

To test your fax setup
1 Press Setup.
2 Press 6, and then press 5.
This displays the Tools menu and then selects Run Fax Test.
The HP all-in-one displays the status of the test on the color graphics display and prints a report.

3 Review the report.
– If the test passes and you are still having problems faxing, check the fax
settings listed in the report to verify the settings are correct. A blank or
incorrect fax setting can cause faxing problems.
– If the test fails, review the report for information on how to fix any problems
found. For more information, you can also see the next section, The fax test
failed.
4 Press OK to return to the Setup Menu.

Make sure you used the phone cord supplied in the box with your HP all-in-one
to connect to the telephone wall jack. One end of this special 2-wire phone
cord should be connected to the port labeled "1-LINE" on the back of your
HP all-in-one and the other end to your telephone wall jack

This special 2-wire cord is different from the more common 4-wire phone cords
you might already have in your home or office. Check the end of the cord and
compare it to the two types of cords shown below.

If you used the 4-wire phone cord, disconnect it, find the supplied 2-wire cord,
and then connect the 2-wire cord to the port labeled "1-LINE" on the back of
your HP all-in-one. For more information on connecting this phone cord and
setting up your HP all-in-one for faxing, see Fax setup.
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.
● 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.
● Other equipment, which uses the same phone line as the HP all-in-one, might
be in use. For example, you cannot use your HP all-in-one for faxing if an
extension phone is off hook, or if you are using your PC modem to send an email
or access the Internet.
● The phone line connection might be noisy. Phone lines with poor sound quality
(noise) can cause faxing problems. Check the sound quality of the phone line
by plugging a phone into the telephone wall jack and listening for static or
other noise. If you hear noise, turn Error Correction Mode (ECM) off and try
faxing again. For information, see Use error correction mode. If the problem
persists, contact your telephone company.
● If you are using a digital subscriber line (DSL) service, make sure that you
have a DSL filter connected or you will not be able to fax successfully. The
DSL filter removes the digital signal and allows your HP all-in-one to
communicate properly with the phone line. Obtain a DSL filter from your DSL
provider. If you already have a DSL filter, make sure it is connected correctly.
Make sure your HP all-in-one is not connected to a telephone wall jack that is
set up for digital phones. 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.
● If you are using either a private branch exchange (PBX) or an integrated
services digital network (ISDN) converter/terminal adapter, make sure the
HP all-in-one is connected to the port that is designated for fax and phone
use. Also, make sure that the terminal adapter is set to the correct switch type
for your country/region, if possible.
Note that some ISDN systems allow you to configure the ports for specific
phone equipment. For example, you might have assigned one port for
telephone and Group 3 fax and another port for multiple purposes. If you
continue to have problems when connected to the fax/phone port, try using the
port designated for multiple purposes; it might be labeled "multi-combi" or
something similar. For information on setting up your HP all-in-one with a PBX
phone system or ISDN line

if you go there please refer to page 82 of the manual or chapter 10

I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.

I beleive it's because they are grounding out on the fax, which then resets some of the functions.

Did you measure if there are any activity on those two lines?
V or Hz?
