One of my customers has one of these boxes and used to use it primarily as a fax so when the machine is turned on it selects fax as the initial setting , they dont use it as a fax anymore and want it to select copy as its initial setting this is the only model like this i ever saw it looks like an hp engine..........is there a way to select copy as the initial setting? dont have a manual and it has limited user functions .....any help would be appreciated
