I just bought my first Mac. It's a mini.I'm trying to get my printer and scanner working. Printer works fine. Scanner is an Epson 640u. I plugged it in, and started Image Capture. No scanner. I downloaded the driver and scan software from Espon. Still can't see the scanner. I don't think this scanner works with 10.3.8. Anyway, how do I remove the software I just installed?
