How do I change baud rate to 9600 on Epson CX9400Fax?

I am using a Epson CX9400Fax with my VoIP phone. I have been able to send faxes, but I cannot receive faxes. I have changed all the settings as advised, except the baud rate. I cann't get Epson to advise: How do I change baud rate to 9600 on CX9400Fax?

If someone can help me, I would be very grateful! I have spent days trying to get an answer on this.

    I am having exact problem. Epson seems to ignore the question. I can't believe they ignored a baud rate change in their engineering in this day and age of digital phone lines and Voip? I have taken everystep there is.

    The answer is:

    It cannot be done!

    I finally called Epson and demanded an answer. They were trying to avoid the question again and I told them I didn't need to go through every thing with them again that I only needed an answer to this question. They finally told me that it cannot be done. It only works on their dot matrix. So, I am taking mine back to the store that I bought it and buying one that I can change the baud rate to 9600!

This fax speed is 33.6 or 33600
You can change settings to 14.4 or 14400 but not to 9.6 or 9600.
Under: Fax Settings you have this choices:
Speed Dial Setup
Scan and print setup
Header and time

Under Communication:
ECM - error correction put this one: off
V.34 - this one is for speed: on - 34400; off - 14400

    I found error in my info it should be:

    1. Press Setup.
    2. Select Fax Settings, then press OK.
    3. Select Communication, then press OK.
    4. Adjust any of the following settings:

    V.34 On (default) - Indicates the speed at which you transmit faxes.
    On is 33.6 Kbps and Off 14.4 Kbps.

    More info:

    ECM On (default) - Indicates whether you use Error Correction Mode to automatically request retransmission of fax data that is received with detected errors.

    DRD All (default) - This feature can be used with a Distinctive Ring Service (Detection)provided by your phone company. With this service, you can have two or more phone numbers assigned to the same line, with each number given a distinctive ring. For example, if you have a phone number for personal calls that's set to ring normally (with a single ring) and a fax number set for a double ring, select Double as the DRD setting. Then the fax system picks up only those calls with a double ring.

    Rings to Answer - Indicates the number of rings that must occur before the CX9400Fax Series automatically receives a fax. You may want to change this setting if you have connected a telephone or answering machine.

    Dial Tone Detection - When this setting is on, the CX9400Fax Series dials automatically when it detects a dial tone. It may not be able to detect a dial tone when connected to a PBX (Private Branch Exchange) or TA (Terminal Adapter) system. In that case, turn this setting off.

How do I change baud rate on Lexmark X5650 in

Just to set your expectation, MagicJack phone service may work but Lexmark does not recommend the printer to be connected to a digital phone signal (e.g. MagicJack, Vonage, etc.) since there are lots of jitter and packet loss in the transmission signal resulting to fax failures. The Lexmark fax machine will have its optimum performance when connected to an analog signal(regular telephone line). But here's how to configure the printer's baud rate. From the Control Panel, press Settings(wrench icon)> Fax Setup, hit Ok > Dialing and Sending, hit Ok > Max Send Speed, hit Ok > set down the speed to 9600 bps. Hope this helps. If you need more assistance, leave a comment and I'll get back to it. Thanks.

How do I change the baud rate to 9600 on an HP Laserjet All in one 3015

The baud rate is usually determined by the receiving machine. When one fax contacts another, they negotiate their send/receive rates. That's an automatic function and not generally adjustable on modern faxes.

Need to know what bod rate is on my fax

older fax machines used a 9600bps baud rate, meaning a transfer rate of 9600 bits per second. a Bit being an 7th/8th of a byte. The newer machines can transfer at 14400bps, which older machines can not read, as its too fast. thats why they asking the BAUD rate.

You should change the Baud rate to 9600 on the machine. This should correct your issue.

Also call vonage and they have some settings they can modify to improve performance.

Good luck!

Receiving faxes with a Cisco ATA 186

More investigation implies that faxing over VoIP, as I am doing, requires setting the fax BAUD rate to 9600 bps or slower. So does anyone know if it is possible to set the BAUD rate on the Dell MFP 1600n multifunction printers?

1 Answer


Make sure baud rate is set to 9600 and error correction mode (ECM) is off. If this does not correct your issue then you may have to contact your provider to adjust your sample rate (packetization). This adjusts the size of the packets and is often a common fix. You may want to run a ping/tracert from command prompt to check for latency and/or packet loss with your ISP. I'm a voip tech and these are the primary fixes for fax issues.
