I have a Panasonic KV S2026c scanner. I turned off my computer and unplugged the scanner to move to another office. When I turned on the computer and plugged back in the scanner the scanner will not work. It says that I need a WIA driver to use this device. Computer will not recognize the scanner anymore. I downloaded what I thought was the right driver but it says that I already have a more updated driver on my computer. Any ideas?
