CAN NOT FAX TO OTHER PARTIES - Brother Sealed Mfc-j430w Wireless Printer Scanner Copier Fax

Do not understand what you mean?
Polling means you dial up the other parties fax and you pull in their document to yours. It checks both yours and their passwords. You effectively pay for the call both ways.

Printing a Fax in Memory If you have Fax Storage ON for remote retrieval, you can still print a fax in the memory when you are at your machine: 1 Press Menu/Set, 8, 4. 2 Press Fax Start. 3 Press Stop/Exit. (See Turning On Fax Storage, page R-2.) Polling For details about the Polling feature, call our Brother fax-back system 1-800-521-2846 (in USA), 1-800-681-9838 (in Canada) and request at the Index. (See Features That Are Not in the Manual, page 6-6 for details.) Polling is the process of retrieving faxes from another fax machine. You can use your fax machine to "poll" other machines, or you can have someone poll your machine. All parties involved in polling need to set up their fax machines to accommodate polling. When someone polls your machine to receive a fax, they pay for the call; if you poll someone's fax machine to receive a fax, you pay for the call. (See Canceling a Scheduled Job, page 6-5.) Some fax machines do not respond to the Polling feature.

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.

you need to check your phone line only

This means poor line conditions, check the connection, make sure its plugged directly to Wall jack and not into any splitters or extentions. You can also try another Jack or wire.

If you are able to fax out to other parties except for one, there may be an issue on the other end.

The only thing that could stop you from sending a fax or not get a dial tone, would be the connection to the phone line. Make sure the telephone wire is plugged into the line jack (not ext jack) and should go straight to the wall, without splitters or extensions. If you still cannot send a fax, try another wire or jack

It does not sound as if there is a problem with your machine. The receiving parties may have given you the wrong number to send to.

Call those numbers from a regular phone and listen for fax tones.

This is an involved process. You first have to register (log in) each of the parties in the group individually as a one-touch speed dial or a coded speed dial. Then you register the group to and list each of the parties in that group.

Rather than give you a step-by-step, you can get the manual here. Wait a few seconds for the page to load. Click on the link for the manual and it will open in a separate window (pdf). Click on the save icon in the upper left corner to save the manual to your computer.

Chapter 6 in the manual gives you complete instructions for registering one-touch speed dials, coded speed dials, and group speed dials.

I would suggest there is nothing actually wrong with your machine, as you can indeed receive faxes from other parties. The problem mostly likely lies with the equipment and/or lines of the sending party. One thing you might suggest to them is to turn off ECM (Error Correction Mode) and/or lowering the sending/receiving speed of the machine - preferably the sending speed of the sending party.

After each number you dial, press "SET" then dial the next number
After you put in your last number hit "SEND"
You will receive a confirmation with a compilation of all the numbers you sent to after all numbers receive their faxes.
