DR MODE - using the machine as a fax with a separate phone line

I have a small business and purchased the MFC-7820N printer. How do I program/set-up the fax capability to that it will "acknowledge" the distinctive ring of someone sending a fax so that it automatically detects the other end to be a fax and switch over (without me being home)? Likewise, when the other end is a person who wishes to leave a voice message, how do I program the machine to know that if it is not a fax transmission it should revert back to a landline so that the person can leave a voice message on the answering machine. For some reason, it is staying in "DR Mode". What is this? Thanks, so much!

you might have to change the settings for the switching time into stand-by. plz have a look into the manual which describes these settings (zero seconds are possible)

try leaving easy receive on and changing the receive mode to manual. when you pick up phone and hear the other faxs' tone, wait for your machine to take over by listening for the chirps. then hang up. if you don't hear chirps from your machine, then press *51.

Im using the Brother MFC 7820n at a hotel. how do i fax? i've tired 9+1+area code+the number, 9+area code+the number and a few others but nothing seems to work, what am i doing wrong?

Depends on the hotel.
Some have a specific dedicated line that allow direct dial (no 9). Some block long distance calls and required the use of a calling card.
Otherwise, dialing 9 should work.
Can you hear the dial tone? What kind of sound do you hear when it fails? Is ti list a fast busy signal? Or do you just hear nothing?
If they have the speaker off, try to call your cell phone from the FAX just to see if it can make an outbound call at all.
Also, try tracing the wire from the fax machine. Make sure it is plugged into LINE and not PHONE. (or the jack with the picture of a wall jack, not a picture of a phone). Some hotel patrons disconnect FAX machines to use the phone line on their laptop modem and then neglect to properly reconnect the fax machine. Also make sure it is connected at the wall.

setting of 4.

page A-4 and Easy Receive on page 4-3.)

the line rings before the MFC answers

Printer says DR mode in use what does this mean

DR Mode means distintive ring. This is if you are using two or more phone numbers on one line. For example, you could have your voice mail number and your fax number on the same line, but when a call comes in to your voice mail the fax will recognize the ring pattern and won't pick up the call. If it is truly a Fax, then your fax will pick up the call by recognizing the ring pattern.

Can't Send or Receive Faxes from MFC-7820 N

You may not need a separate fax line from Vonage. If you don't need a dedicated fax line, you can try changing the "Bandwidth Saver" settings on your Vonage voice line from your account on the Vonage website. Perform the following:

1. Login to your Vonage account online and click the "Features" tab.
2. Scroll down to the "Bandwidth Saver" link and click on the "Configure" button.
3. You will see a scrollbar with 3 settings: 30kbps, 50kbps and 90kbps

NOTE: My "Saver" was set to 90kbps (Highest Sound Quality) by default.

4. Click on 30kbps (Normal) and click "Submit".
5. Wait about an hour before testing as it could take that long for the change to take effect.
6. Send a test fax to the HP fax test service at 1-888-hpfaxme (1-888-473-2963).

NOTE: This is a GREAT service provided by HP. If your fax goes through correctly, you will receive a return fax within five minutes.

We upgraded to Verizon FiOS and never thought the increased upload speed (4mbps) would present an issue sending faxes. WRONG. We never had fax issues with DSL, Comcast or even Broadstripe VOIP service but for some reason Vonage + FiOS = no fax. That is until we set our Vonage VOIP sound quality to "Normal". Our phone voice quality has been much more reliable since throttling back. This sentiment has also been shared by other Vonage users who have experienced echoing and noise when utilizing the higher quality settings.

Your phone coversations may not have FM quality sound but they will have AM quality and usually that is just fine.

If your fax machine has a Telephone Answering Device (TAD) setting, you can share your voice line with your fax machine and be able to receive faxes and voice messages. Hopefully this will work for you.

Not able to send fax to an eFax number

I've had the same problem before. I don't know if it will solve your problem directly but I can offer a work around or two.

1. I have an efax number but with a company called , I fax stuff to other customers using callwave and my MFC 7820n completes each fax successfully. So if you can get yourself a callwave efax number you can fax to yourself and forward fax as an email to your intended party.

2. Or, you can use your mfc 7820n to scan your fax docs as a pdf directly to your computer and then emailing them to your intended party.

Unfortunately it might be a brother issue because at the office when I use the hp fax machine instead of the brother machine, the hp faxes to efax numbers without a problem.

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.
