I have an HP 2510 printer. I cannot use it to fax because once I plug the phone jack into the printer I get a busy signal. If I plug the jack into a phone, it works fine. How do I get the printer to...


Hi irwinbadin,

HP fax products are designed so that other telephone equipment can be connected on the same line as the fax. The unit must be connected first using a two-conductor fax/phone cable like the one that shipped with the HP product. Using a four-conductor telephone cable may cause problems receiving faxes or calls.

There are two different types of phone cables. There are two-conductor phone cables like what originally shipped with the HP fax product and there are four-conductor cables. HP fax products are designed to work with a two-conductor phone cable. Look at the end of the cable and verify that it has only two copper leads or wires. Replace any four-conductor cables with a two-conductor cable. Only two-conductor phone cables should be used to connect the all-in-one to the phone line.

Figure 1: The difference between a two-conductor phone cable and a four-conductor phone cable

Step one: Connect the phone line to the fax
The fax will have two or three sockets (or jacks) for phone lines. Some of these may have a removable plastic plug in them. These sockets will be labeled with text, To Wall Jack , or with a graphic of the wall jack. See Figure 1 below.

Plug the two-conductor telephone cable that came with the HP product into the telephone wall jack. Then, plug it into this socket as shown below.

In areas with above ground telephone lines and electrical storms (lightning), it is a good idea to purchase a telephone line surge suppressor and connect it between the telephone wall jack and the fax. This will help prevent damage to the fax from a lightning-caused power surge on the phone line.

Step two: Add other phone-line devices
To connect other telephone devices, use the other socket (or sockets) on the fax. These are identified by text or with a graphic of a telephone and/or computer.

Connect a caller ID unit between the fax and the telephone.
Use the information below that matches the devices you need to connect.

Fax and telephone
Connect a single-line telephone to one of the added sockets on the fax. The telephone will share the same phone line as the fax. See the illustration below.

Fax, answering machine, and telephone
When a telephone answering machine and telephone are connected, connect the answering machine to the fax and then connect the telephone to the answering machine as shown below.

Fax and computer modem
To use a fax and a computer modem on the same phone line, connect the fax to the computer modem. The modem socket on the computer may be labeled Line or Wall jack .

Fax, computer modem, and telephone
To use a computer modem and a telephone with the fax, connect the computer modem to the fax. Then, connect the telephone into the second phone line connector on the computer modem or the third fax socket (if it is available). The image below shows how to connect a computer and a telephone to a fax with two sockets.

Fax, modem, answering machine, and telephone
The image below shows how to connect a computer modem, answering machine, and telephone to a fax. Connect the computer modem to the fax, then connect the answering machine to the computer, and finally, connect the telephone to the answering machine.
If the fax has three phone line sockets instead of two, some of the devices can be connected to the other phone socket on the fax.

My Brother MFC7340 Fax Machine will not send faxes it has a busy signal always and a busy signal when someone tries to fax me.


Hi,
You need to reset the memory, since previously you have dialed some number, which is not able to connect. So restart the printer. Unplug the printer for 10 minutes and plug back the power to the printer.

Hope this helps.

Cant send fax dials squeals and cuts out and busy signal?


Hi There!
Please check if the phone line where the fax machine is connected is working. You may try to disconnect the fax machine from the walljack and connect known-working telephone on that jack and try to dial/call anyone. Because sometimes this issue can be caused by the problem on the phoneline.
Hope this helps. Please rate if it works. Thanks

I am unable to use my fax when it worked before, say's busy/no signal. The last time I was able to use it was in January 2010


Verify the connectivity (phone line) first by pluging a working telephone in the wall jack, than test the cable from the wall jack to the fax, you could install a Y to plug a working telephone with the fax on the same line to spy on what is happening when the fax is engaging a connection.

Cheers!

WE CANNOT RECEIVE OR SEND FAXES, BUSY/NO SIGNAL


Plug a phone into the jack and check to make sure you have a dial tone. If not telephone company needs to be called. If dial tone it may be the other number you are trying to fax to. try calling the number from phone and see if it picks up.

Receiving faxes


If you are receiving a fax and you pick up the telephone before the fax machine answers it, the fax will never be able to respond to the fax being received. I assume that is whats happening. If you have a phone connected directly to the fax machine and you pick it up from that phone, the fax machine should transfer to itself after 2 seconds when it recognizes that it is a fax machine.
If you are going to do it from anywhere else, you need to get a fax detector device connect it to the main phone jack, and have the fax machine go to the fax jack of the connector and the other phone in to the other lines, make sure you have enough sockets on the fax detector.

thanks

Difficulty sending a fax


Hello. Please make sure your telephone line is plugged into the correct outlet.

Most fax machines typically allow you to plug the line (the cord that goes from the fax machine to the wall jack) and and a telephone (the telephone connects to the fax machine).

In order to fax correctly, you must plug the line into the jack with a block (looks like a 'T') marked on it. Do not plug the line into the jack marked with a phone hand set marked on it.

This shoulds in detail how to connect the line properly. For this printer the line cord must be plugged into the jack labelled "L"

This will show you how to actually send the fax. On your PDF View select page 42.

Problem sending & Receiving Fax Imageclass D880 Canon All in one printer


#0018 indicates there was a problem with dialing, but it should show for sending faxes only. Since you can neither send nor receive faxes, and are getting a message saying "no signal", make sure that the phone line is still securely connected to both the L (line) jack on the machine and the phone jack in the wall. If it is, plug another phone into the accessory jack on the machine, and check to see if you are getting a dial tone. It seems like the machine is not able to communicate through the phone line.

Fax doesn't recognize incoming phone call


Try this: using a cell phone, call your fax. Listen on the cell for a busy signal, fax tones, dial tone, etc. If the fax does not answer the cell, check the following: make sure the phone line is plugged into the LINE jack on the fax, NOT THE PHONE JACK. The phone jack is to connect a TELEPHONE to the fax. If problem still exists, press MENU on your MFC, and scroll to GENERAL SETUP, FAX. Scroll to SETUP RECEIVE, and, after writing down the settings, try changing the RING DELAY or RING TIME settings. If problem is still there, press CLEAR/BACK button until GENERAL SETUP appears on screen. Scroll down to INITIAL SETUP, and select RECEIVE MODE. Try changing RECEIVE MODE settings. Write them down before you change anything.

Multiple fax copies only 1 or 2 get through


First check to see if all 5 are bing sent. Sometimes paper sticks to each other and you may only see 1 or 2. Also your telphone line has a lot to do with it. If you are using a digital telephone line with your internet line such as a vontage telephone, the signal is takene from your internet line for your telephone and sometimes such as when you are on the internet and trying to fax, you do not have enough signal strength. sometimes sutting off the internet works. Also what does the report say from your copier/fax are 5 pages being sent. In the set up this Canon you can get a report after you send a fax....
