Help. I bought a HP scanjet 3970 and hooked it up to my G4 Mac, The scanner goes on when I start the computer but when I go to scan it does not seem to recognize the software. I cannot scan by using the buttons on the scanner either. It also will not allow me to change the preferences. Everything freezes. I had the scanner plugged in through a Belkin TetraHub but I got no response so I went directly through the Mac. Still nothing. I now also get a message when I power up that says "insert iomega disk" which I cancel. I have practically the same set-up at home with my laptop G4 and a different model HP scanner and works perfectly.
