Question about Brother FAX-575 Plain Paper Thermal

2 Answers

Transmission I am using my 575 on a dedicated Fax line on my Vonage VOIP internet phone system. I also have a purely voice line. Problem is, that my failure rate on transmissions is almost 75%. I almost always get an "NG" - Poor Line condition error message. I have tried everything: 1. Set machine to "Basic" transmission mode 2. I use *99 prefix on all transmissions 3. Tried using "International" mode on individual faxes Vonage says that most Fax machines need to be taken off "ECM" mode to allow for less line sensitivity....but I can't figure out how to do this on the 575. Has anyone ever had similar problem.....Does anyone know how to change or disable ECM feature on this machine. Does anyone have any other thought ??? Thanks Phil Green

Like on my earlier posts. VOIP is not reliable for fax transmissions. Actually dropping the tx and rx speed to to 4800 bps might help. Successful transmissions depends on your bandwidth of your internet service. VOIP faxing suffers from latency, distortion and packet loss errors.

I found the manual if you need it. it is located here: http://www.brother-usa.com/Data/Documentation/Fax/User/UM_FAX575.pdf If you cannot sort it out with the manual, I suggest that you contact Brother USA and see if they can assist you. their telephone number should be on page 1 I think Good Luck

Fax problem

I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone? When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work. If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP. If you can verify that, we can go from there.

My problem is that I have just purchased Vonage as a VOIP phone line. I have a HP LaserJet 3055 printer/fax and I am trying to send faxes but it does not work. I was instructed to lower the baud rate,...

Configuring the V.34 setting to Disable (Enable is the default setting) to lower the speed.


Voice over IP (VoIP) services provide normal telephone service, including long distance service through a broadband Internet connection. These services use packets to break up the voice signal on a telephone line and transmit it digitally to the receiver, where the packets are reassembled. The VoIP services are often not compatible with fax machines.

If you continue to have problems faxing, contact your VoIP provider. Because the installation process varies, the VoIP service provider will have to assist in installing the all-in-one fax component.

Although a fax might work on a VoIP network, it can fail when the following events occur:

• Internet traffic becomes heavy and packets are lost.

• Latency (the time it takes for a packet to travel from its point of origin to its point of destination) becomes excessive.

Will not send a fax

There is two things i can think of that can cause this. The number one is if you are using a voip carrier (like vonage or att voip or comcast digital voice) they are usually not compatable with fax machines. You will need either a dedicated fax line or you will need to whats called a fax line from vonage or comcast, or from your voip service. If you are using a phone line test to make sure you have it connected correctly buy simply dialing your cell phone or a friends cell phone (let him know you are going to test) once you do this you will hear a ring and an annoying fax machine tone buzzing in your ear. if this is the case and you do have everthing connected correcly i would put a trouble ticket in with your phone company, to test the line condition of your line (to make sure its not shorting or anything like that)
i hope this helps if there was more information i could do better but hopefully this will help out a bit.
Thanks

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.

Faxing using voip

I can tell you after trying Vonage a few years ago and them telling us to change all sorts of settings on the machine, that faxing never worked and now I have no idea what the factory default settings should be.  So, if you decide to try it, WRITE DOWN THE DEFAULT SETTINGS so you can switch them back if you need to!

Can't send fax

Greetings,

Seems that you accidentally ended the chat session.

Here's what i got, your phone service is on VOIP

VoIP is voice transmission over a broadband Internet connection instead of a standard phone line. Basically, Vonage converts your voice into data and sends it like an email.

Fax machines, like yours, are designed to work with the regular phone lines. As your phone line is digital, the functionality of your all-in-one printer & fax cannot be guaranteed.

Vonage also offers a dedicated fax service and you might want inquire them about that.

Keep us posted and thank you for using our service.
FixYa for all your troubleshooting needs.
