External TAD If I have an external TAD and it is impossible for it to be attached directly to the EXT jack on the FAX-575, is there a work around or a mode I can set that will allow both the fax machine and the TAD to work on the same line?

I have a Brother Fax 2820 at home. It is connected to a TAD. I want an external fax machine to send and bypass the voicemail greeting and print the fax. I thought I set the machine to TAD. Any other...

try this paul. hook your phone line from your wall jack to your "line" jack on your fax. then run another phone line from your "external" jack on your fax to your "line" jack on your TAD. now, make sure your fax machine is still set to TAD. here is whats important...set your TAD to 4 rings or less. 2 is the recommened setting. also very important...when you record your outgoing message on your TAD, make sure you leave about 5 seconds of silence before you start recording your message. the reason for this is the fax machine needs to "hear" the CNG tones that originate from the sending fax so that it knows its a fax and then can take over the call. if it doesn't hear those tones because of noise (voices, etc), it will let call go to TAD. you can try to set your TAD to 4 rings, but that doesn't leave much time for fax to "hear" these tones. if you set to 4 and don't get all your faxes, try lowering the setting to 2 or 3 rings.

good luck and hth,

I have changed from a desinated fax line to sharing a phone and fax line. the fax machine rings along with the phone however the fax does not answer. i was told to purchase a ring decipher but cannot...

Your fax can share the line with your phone, but it needs to be set to answer or not, depending on your equipment and choices.You can download the manual from Brother here. The receive modes are explained on page 5-1.
If you're often out when faxes or phone messages might come in, you probably need to plug an answering machine into the back of the fax (the EXT. jack) and put the fax in FAX / TAD mode. (TAD stands for Telephone Answering Device. Be sure the TAD is set to answer before the fax does. The fax will pass the phone call through to the TAD, and if it hears the beeping of another fax sending, it will cut off the TAD and take the call.
See the manual for more info and other options.

Brother Multi function centre with fax, MFC 885CW we have the setting on F/T, it answers a fax after 2 rings, if a call coming in it keeps ringing, but on callers end it keeps beeping fax noises, callers...


I had the same problem using my Brother MFC 8460N fax on the same line as my regular telephone, which has an answering machine.

There was nothing wrong with my equipment. It was a set-up issue. I solved it as follows, and maybe this will be helpful to you:

Here's what I did, step by step:

1. Put your MFC and your telephone near each other, and within reach of a phone wall jack.

2. Go to the fax machine. Take the telephone line with the clip on the end of it that comes out of the fax machine. Put that into the telephone wall jack.

3. Go to the answering machine. Take its telephone line with the clip on the end of it and put that into the BACK OF THE FAX MACHINE. The port on the back of my fax machine says something like EXT TAD which means external telephone answering device.

4. Go back to the fax machine. You'll now need to play around with the menu options for the fax. My Brother MFC shows this stuff in a little screen on the front. Try and find the Fax Setup options. Next, try and find the Fax Receive options. If you do, select something like External TAD fax receive mode. Do not give up, you're almost done.

5. Next, set ring numbers on both devices, the fax machine and the answering machine. I set both devices' ring numbers to 4. I don't know if these are the optimal settings, or what happens if you set them at different ring numbers. I only know that a "4 and 4" setting works for me, and am not inclined to mess with it.

6. Final detail: the setup should be transparent to a voice caller. Someone who is sending a fax, though, might be a little confused IF, like me, they lean over to listen to their fax machine dial and screech, just to be sure it's working. Such a person may faintly hear my outgoing answering machine message before they heard my fax machine's screech kick in. They might think that they had a wrong number, cancel the fax, try again, call me with questions, etc., etc. So I changed my outgoing message to something like: 'You have reached xxx xxx xxxx. To leave a voice msg, please wait for the tone. To send a fax, please continue the transmission and it will be printed. Thank you!'

That's it. Hope this was helpful.

Still can't get fax not to pick up when answering machine is connected.

if you have the fax-575 there should be a TAD setting.

This is the setting you would use if you're using an answering machine on the same phone line as your fax machine.

To set the Recieve Mode :

Press Recieve Mode. The LCD display shows your current selection.

Continue to press Recieve Mode until your new selection appears. After 2 seconds the screen returns to the date and time display, along with your new Recieve Mode setting.

The 4 Recieve modes are Fax Only, Fax/Tel, TAD:Answering Machine, Manual.

Hope this helps!!!

What does "TAD" mean when it appears on the screen?

TAD is Telephone Answering Device. TAD mode is the only mode that can be used with an external telephone answering device (unless you are using a distinctive ring number for receiving faxes). Your telephone answering device must be connected to the jack on the fax machine (labeled "EXT" for USA). When someone dials your telephone/fax number (to send a fax or to speak to you), all the telephones (including the FAX) will ring according to the number of rings you set on the TAD. The Ring Delay setting is not recognized in the TAD mode. If you do not answer the call, the TAD will answer. As your outgoing message is playing, the Fax is in the background, silently listening for fax tones. If the FAX hears fax tones, it will automatically go into the receive mode. If the FAX does not hear fax tones, it remains silent, allowing the caller to leave a message. The above information is correct for a Brother fax machine. Is your fax automatically picking up the call or do you have to push a panel button to start the receive fax process? Perhaps the fax is already "in" your fax machine's memory and only needs a manual printout. Check the fax call log.
