Question about Brother FAX-2920 Plain Paper Laser

HISSS on line; no dial-tone; no fax in or out

This unit is linked to a DSL line that splits to a router before entering fax -- line has DSL filter between splitter-out and Fax-IN port.

  • The machine has previously worked well as Fax, but always had a line HISSS heard on handset (we don't care, as we don't use the phone feature).
  • Now, the Fax does not operate, there is no dial tone and the HISSSS is still present.
  • No trouble advisories show in machine window, date shows correctly. The machine printer operates properly and copies as it should.
We have tried:
  • Disconnecting the line from the splitter and the network the line shares, and fed the line directly into the Fax with no luck.
  • A different DSL filter. No luck.
  • Rebooted the unit, no luck.
Anyone have any thoughts?

    So obvious, yet easily missed. Actually, I always thought a DSL required a dial-tone -- it doesn't. Verizon provides DSL service even without a dial-tone, so the problem was in their switching staiton. Many thanks

I have exactly the4 same problem on a Samsung fax machine. Works fine in the office on ADSL line/internet and filter. At home, no dial tone, ADSL line/internet and filter. Have tried disablingall other fones on line and plugging direct into line - still does not work but the old grotty fax machine does. Not logical!

It sounds like you may not have any dial tone. the hiss [white noise] you are hearing is from the dsl modem.try plugging a regular corded phone into the jack to check for dial tone.if there is none,call your phone company.also try plugging the fax machine into another jack where you know there is dial tone.
good luck

Why won't the fax work?


My recommendation would be to hit the speaker button when sending a fax to hear why your fax wont go through.

When you hit speaker you should have a clean dial tone, then when you start dialing and the tone stops make sure you don't have any static or noise on the line.

There are several reasons you might get a NG error. One is the fax line you're trying to send to is busy. Maybe it's a phone line not a fax you're trying to send to. Maybe you need to dial a 1 or 0 for long distance, maybe your fax line has noise on it.

Using the speaker can help troubleshoot what the problem is.

Phone off hook message


A "Phone Off Hook" message is not an error. It simply indicates that a telephone receiver is off the hook (the handset is lifted) and the telephone line is open. This message would be expected in the following situations:
  • A modem on the phone line is accessing the Internet.
  • A phone connected to the HP fax (or the same phone line) is using the line, or the handset has been lifted.
  • A credit card machine is using the phone line.
  • Another electronic device is using the phone line.
  • The Start Fax button was pressed with no telephone number entered. Pressing Stop or Cancel should return the display to a ready state.
When the other device is no longer using the phone line, the display should revert to the normal message. Checking the phone line The most common reason for this message is when a dial-up modem is accessing the Internet on the same phone line. Just as two phone calls cannot come in at the same time, two devices cannot use the phone line at the same time. If a broadband modem (such as DSL or ISDN) is on the same phone line and the message appears all the time, please contact your Internet provider for assistance. Even if a dial tone is present when listening to the phone line, the HP product may detect the broadband data connection at the higher line frequencies. Broadband modems must have a line filter installed to work correctly. Contact the telephone company for assistance. Please follow the directions below to verify functionality.
  1. Verify that the phone cable going into the HP fax product from the wall jack is a two-conductor cable type, not four-conductor. A two-conductor cable, like the one that ships with the HP product, has two copper leads in the connector. The connectors are usually clear, making it possible to see how many copper leads are inside the cable. Replace a four-conductor cable with a two-conductor cable.
  2. Disconnect the phone cable from the back of the HP product and the message should clear. If the message does not clear, unplug the power cable from the back of the unit, wait 15 seconds, and then plug in the power cable. If the message persists, see the "Problem still exists" section below.
  3. Disconnect the phone cable from the HP product and connect it to a single line phone. Pick up the handset and listen for a dial tone. If no dial tone is present, replace the phone cable. If a dial tone is still not present, a problem exists with the phone system. Continue with the steps below if a dial tone is present.
  4. Plug the phone cable back into the HP product and hang up any phones with a lifted handset.
  5. Disconnect, one at a time, other phones and devices using the same phone line. Check the HP product display after disconnecting each phone or device. If the message clears after disconnecting a phone or device from the line, the problem is with that phone or device.
  6. If the message still exists after unplugging all other phones or devices, see the "Problem still exists" section below.
Problem still exists If the problem still exists after performing the steps above, the line interface unit (LIU), the part that the phone line plugs into, may be defective or the HP product may need to be serviced.

Telecom Issue, when a Netgear router (DG834G) linked to a small server unit, dissconnects the telephone line. The router works fine but no dial tone on the phone side of the micro filter. Any assistan


a POTs (plain old telephone) line should never be connected to a router. that adsl filter does not make a phone line share a data line.
ADSL is a type of internet service supplied over a phone line. think of it as raw (unusable) when its on the phone line. then you use your dsl filter/splitter to feed the raw internet into a special dsl modem and the other port can be used by a standard phone.

you will know a dsl modem when you see it because its uplink or internet port will only be big enough to fit a phone cord into, not an internet cord. these dsl modems then feed usable internet to your routers and all devices on your network. but, like i said before, at this point it is too late for your phone and internet to share the same wire.

OK, thats not entirely true

pin out of RJ45 internet
1=orange/white *
2=orange *
3=green/white *
4=blue
5=blue/white
6=green *
7=brown/white
8=brown

1,2,3+6 are used in a typical network

if your network is typical you can "get fancy" and use 4,5,7+8 for telephone or even put 2 data lines on the same wire (not recommended for long distances). however, this may involve cutting some wires and splicing them together or something.

Panasonic fax machine plays "not


First, the phone line to your fax machine should go through the filter.
Also, you haven't mentioned if you can just dial and call someone. Can you?

One way to test it is to dial manually as you would dial any telephone number.

Insert the document to be faxed, lift the receiver on the fax machine, listen for a clear dial tone, then dial the number.

If there is a fax machine at the other end you will hear the chirping sound after a few rings. Then press START and see what happens.

Lexmark x2470. Fax solutions not working after going high speed


Please check that the Phone line for faxing is connected to a seperate NON FILTERED phone line. Not to the dsl line. You can use a line splitter for this. Also the dial up modem may need to remain in your computer for the fax software to dial out. Hope this helps.

Fax nightmare!!!


If you have a BT line and use the 1571 answering facility , when you have a message waiting the dialling tone changes from a constant tone to a split tone. This is to let you know that you have one or more messages waiting.

In order to get the dialling tone to revert to the constant tone you have to deal with the waiting messages in accordance with the options provided i.e Save, Listen Again or Delete. BT say the Split Tone is to let subscribers know when they have a message waiting. This should resolve the Fax problem.

It certainly worked for my phone/fax system.

Good Luck
