I am not able to send/receive to some area codes due to a condensed phone system, and am being told I need to increase the baud rate of my Okifax to 9400. I have tried to locate a manual, but do not have on on hand.
I have had this Oki since 2002, and have had no problems until improvements interfered. Can someone guide me through changing the baud rate?
Try the following with the machine in standby mode. (no document fed) Press MENU/EXIT key ONCE. Press RESOLUTION key TWICE. LCD display should indicate "Technical Prg." Press DOWN ARROW key ONCE LCD -display should indicate "2 Setup" Press RIGHT ARROW key ONCE LCD display should indicate "Setup" Press the DOWN ARROW key TWELVE times. LCD display should indicate "13>H/Modem Rate" Press the RIGHT ARROW key ONCE. *** NOTE WHAT IT IS ALREADY & DO NOT FORGET IT IN CASE YOU WANT TO UNDO *** Press the DOWN ARROW key repeatedly to change the setting to 4.8, 9.6, 14.4, 28.8 or 33.6K. For "9400" set it to "9.6" (9.6K = 9600 Baud)
Also note that for this to fix your problems I would expect to find your machine is currently set to 14.4 or higher. Change it and see how it works for you. If it is no good, you can always change it back to the original setting.

Check the baud rate of your transmissions. Slow them down to the slowest setting and send a test fax to a helpful person. Slowly increase the baud rate (communication data speed) and send the fax test. When the fax doesn't show up on the receive site, then step one baud rate speed back, and save the setting.
It could also be your fax that is faulty, or even the receive sites fax, also being faulty.
To test your copy-head, insert a document into your loading section of the fax and press copy. If the copy prints out fine, then you know the head is reading correctly.
It is also possible that the receiver fax (the other end) has a printhead failure.
The baud rate is automatically set by the machine when it connects to the remote machine. The machines start at the highest speed and drop down until both machines can send/receive without any errors then they send the pages. You can not manually set the speed.
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.
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.
That's not even a coherent response. Even analog phones go from an analog signal from your home, to a digital signal at the carrier, to an analog signal at the recipients end. It all goes digital at some point.
Fax machines work fine with a digital phone. The baud rate may need to be lowered in some cases, but working for a cable company, I've personally worked with hundreds of fax machines that work just fine.
Try lowering the baud rate and/or using a DSL filter if you are having problems. If you are unable to find the baud rate or speed setting on your fax, you may want to contact Canon to find out how.
Because you are using a VOIP service it can from time to time lose connection briefly. The slower the speed the less data can be loss do to network congestion. It also gives the error correcting function of the receiving fax a better chance of filling in any lost data.
9600 is a good choice becasue the industry minimum is 9600. This means you will be able to communicate pretty much any fax thats is still tickin today. Raising the speed will get you a faster transfer but will also increase the chance that you are sending data at a faster rate than the recieving fax can send.
2. How to change the baud rate....
Press Menu/Set, 2, 0, 1.
Press ▲ or ▼ to select Basic or
Normal (or High*).
* High is available for FAX-2910, FAX-2920
and MFC-7225 only.
Basic reduces the modem speed to 9600
bps. Unless interference is a recurring
problem on your phone line, you may
prefer to use it only when needed.
Normal sets the modem speed at
High sets the modem speed at
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?
Do you have an analog phone line or are you trying to run it through a PBX system? I was just having this discussion with RKS tech support. Their fax software was hanging up as soon as the connection was established and all I had available was a VOIP phone line. It took 4 tries but I found a US Robotics fax/modem that worked fine in class 2.0 mode.
Newer fax technology adjusts transmission speed automatcally, so no adjustment is necesary. therefore, there is no menu option to change it. Your problem resides either on your phone line or the one you are trying to connect to. Call the other people and ask them if thei are receiving without problem. If you are able to transmit elsewhere and the other party is receiving from everywhere, try turning off the ECM option on your unit.
