Cobbco 0 Posted February 11, 2013 Just purchased a used 48" Summa D120 at a close out sale. Try to connect via USB port and it seems to disable the port. Tried the cable off of my graphtec and it does the same thing. Downloaded usb drivers off the summa site and it doesn't help. Happen to anyone else? Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted February 11, 2013 give Summa support a try. I can't think of 1 person on here, that owns a Summa, but there is probably 1 http://www.summausa.com/support/ Share this post Link to post Share on other sites

dwp99 283 Posted February 12, 2013 I have a D60 and this is what I do. hook up the plotter to the usb and turn it on. Run the plotter software it will find the plotter and install the drivers. Another thing I found out. If for some reason you have to disconnect the plotter from the computer and don't get it back in the same USB port, you have to reinstall the software. Great plotter by the way, I've had mine for some time now and I bought it used. Still going great. Share this post Link to post Share on other sites
