Hey Mitchl. My name is Aaron, I have inherited the CopyXpress network faxing problem. I unfortunately have no experience setting up copiers and the like although I do have experience in setting up small computer networks with a single router. Am I correct in saying that in order to use the "networkfax" utility from the KM website, that I need the su-3 board? And that if I want to get around this I have to set up the computer to fax from its modem?
