Fax was set for two line use, now is using only one - how do we change the settings?

Adding another PC with a wired Ethernet connection would be easiest by adding an Ethernet switch, assuming you have another outlet. Depending on the network speed, this can be really cheap. I've seen Gigabit 8 port switches for $20 retail. 10/100 Mbit switches are cheaper. Higher speed network switches are more expensive.

Adding a phone line could be more of a problem. There are basic telephone jack splitters if you want the new desk to share a phone number with the fax. See https://www.amazon.com/phone-jack-splitter/s?k=phone+jack+splitter . This would act the same as using a Telephone handset jack that is on some printer/fax machines. However, if the person at the desk picks up the extension before the machine does, that individual would have to manually start the Receive Fax process on hearing the tones. Similarly, the person using the phone would have to wait for the Fax to end its call to use the phone line for anything else. You could also use a junction box to split the line outside the wall jack.

Using a junction box might also let you create a L1 and L2 wire from your phone service to that jack. Then you could use a specific L1+L2, L1, L2 splitter at the jack, Amazon.com: C2G 41062 Two Line Telephone Splitter L1 + L2: Electronics . Then each phone would get its own number. This depends on how your office adds phone lines.

I hope this helps.

I am confused as U DID YOU MEAN L1 L2 L3 SOUNDS LIKE 3 PHASE, IF SO TO CHANGE ROTATION JUST SWAP ANY 2 WIRES. IF NOT L1 IS A LINE L2 IS A LINE A. 3 MAY BE A 110 220 SETTING .. NEED MORE INFO

hi, i have the canon jx510p and I cant seem how to change the settings on fax for distinct ring.. I have this fax system ina duet line

Please help

If you had it set up to be on a fax line with a special ring you will have to change it to normal ring line and set it to auto detect non fax ring.

Use the HP Fax Test
The telephone number for this service is 1-888-HPFaxme (1-888-473-2963). The fax service receives faxes and returns faxes within 5 to 7 minutes to the number contained in the fax header. Solution two: Run a fax diagnostic test

1. Load plain white paper into the input tray.
2. Press the Setup button ( ) on the product control panel.
3. Press the right arrow ( ) to select Tools , and then press OK .
4. On the Tools menu, press the right arrow ( ) to select Run Fax Test , and then press OK . The fax diagnostic test prints.

Solution three: Check the telephone line and change the HP fax settings Step one: Test the telephone line

1. Disconnect the telephone cord from the back of the HP fax product.
2. Figure 1: Two-wire telephone cord
3. Pick up the handset of the telephone and check for a dial tone.
   
4. On the single-line telephone, dial the fax number of the receiving fax machine.
   • If the receiving fax machine answers the call, continue with the next step.
5. Hang up the single-line telephone.
6. Use a second telephone line or a cellular telephone to call the telephone number assigned to the HP fax product.

Step two: Change the HP fax settings

2. Press the Setup button ( ) on the product control panel.
3.

4. Use the HP Fax Test Service to try to send and receive a fax.

If the HP fax product still cannot send or receive a fax, continue to the next solution. Solution four: Check VoIP digital telephone line Using a VoIP telephone service can cause faxing to fail because fax transmissions are sensitive to the timing of the signals used to transmit the fax. If using a VoIP digital line is necessary, changing the Fax Speed Adjustment setting to Medium might improve the ability to send a fax over a VoIP telephone line. Use these steps to change the fax speed adjustment to a lower speed.

You have the wrong adapter probably. Most common types are single line splitters and will not work like you want. They only split line one and 2 gets blocked out as they only have 2 copper connector on the plug centered to get line 1 only. If you want to use an adapter you will need a 2 line splitter like this one:http://www.trianglecables.com/tellinsplitl.html
A simpler solution is to plug your fax into your phone. On top of your phone are multiple jacks labeled L1/L2, L2 only or L2/data. Plug your phone into the wall using the L1/L2 jack then plug your fax into the L2 jack and this will work fine and still allow you use of line 2 on your phone. If you don't want to hear the ring then set your fax machine to auto answer. Hope this helps you.

Try calling your fax machine with a cell phone to see if the fax answers. If not, check that the phone wire to the fax is plugged into the LINE socket, NOT THE PHONE SOCKET on the fax machine. Next, go to the MENU on the fax.You may have to check or change one or more of the following settings by trial-and error to fix the problem. BEFORE YOU CHANGE ANY SETTING, WRITE DOWN OR PRINT OUT THE ORIGINAL SETTINGS. In the MENU, find FAX SETTINGS, FAX SET-UP, or INITIAL SETUP settings. Try changing one or more of the following: PULSE/TONE, RECEIVE MODE, SEND MODE, RING DELAY, RING TIME, OVERSEAS MODE, etc.

set baud rate to 9600 or slow
set resolution to standard
set error correction mode (ECM) off

if fax has overseas mode turn it on

vonage can make changes to the line that could help, if your using a voice line with call waiting use *70 prior to the number to disable call waiting for that call

Slim1234,
          A multitude of problems might cause receive problems, and the User's Guide has no "receive Problems" section under troubleshooting - so here goes:

        If I had to guess right off the bat, your problem is probably
that the FAX is in "FAX Storage" mode, and is out of memory.
In this mode, it will print FAXes until it runs out of memory.
See problem "g" below.

   a. Voice mail active on the line - if voice mail and FAX-2820 are
       set to answer the line on the same number of rings, there's
       no way to know which will answer first.

   b. Voice mail active on line - if voice mail is set to answer in
       fewer rings than the FAX, then the FAX will always lose
       (but you'll have no problems Xmitting).

   c. Call Waiting active on the line - the call waiting "boop" will
       kill incoming FAXes (and outgoing FAXes too, but your
       personnel will retry the outging ones until they succeed
       and you may only hear complaints about incoming FAXes).

   d. Your FAX-2820 is set to "Manual" or "External TAD" mode.
       Reset it to "FAX only" or "FAX/Tel" mode (depending on
       your office use of the FAX telephone line).
       How to do this: Menu/Set,0,1 <up/down to select mode>
                              press Menu/Set.
   NOTE: your LCD display tells you your receive mode:
       Mine says "Sleep 22:08 Fax", telling me I'm in "FAX only"
       mode, and its 10:08 PM.

   e. You've set the FAX to RING DELAY - if so, the FAX
       must win. Setting ring delay to 00 tells the FAX to answer
       the line silently (an advantage for a busy MD's office).
       How to change this: Menu/Set,2,1,1
       Ref: FAX-2820 User's Guide p.4-2

   f. You dont have a shared (FAX/human) line set to
     "Easy Receive"; if someone answers the call and
      Easy Receive is off, then they need to press START on
      the fax machine front panel or dial *51 and hang up.
      How to change it: Menu/Set,2,1,3
      REF: Fax-2820 User's Guide p. 4-2

  g. You may be set up for "FAX storage."  In this mode, received
      FAXes will be stored (and printed) until you run out of
      memory (quickly done on a Brother FAX-2820), then you
      get nada (but sending FAXes still works).
      How to reset this: Menu/Set,2,5,1 <up/down>
      REF: Fax-2820 User's Guide p.6-2

  h. You may have set up FAX forwarding.  In this mode, sending
      FAXes will work fine, but all incoming FAXes willl be sent
      to another telephone number.
      How to turn it off: Menu/Set,2,5,1 <up/down>

      If this laundry list of (sending OK, Receiving dead) scenarios
 doesn't resolve the problem, email your FAX number to me
and we'll do some cross-country FAX debugging.

P.S.
      The above features may have been set remotely by a
   nefarious (or somewhat knowledgeable) individual - remember
   that a little knowledge is a dangerous thing (even for
   FAXes). See (extensive) remote programming instructions
   on p.6-6 of the User's Manual.

   source of the remote programming:
