Epson Perfection 1670 used to work fine. Now when I scan a document (any
document) I get a white page. The scanner responds to all commands from the
software (it will preview and scan when tasked), and I've tried all different
settings. I've tried different software, too (the Epson Twain software, and
VueScan). No joy.

The FAQ at the Epson page for this scanner says that the scanner "may not
work properly" if a USB cable other than an Epson cable is used. What cable
should I use? I've been using one that I usually use for my Canon inkjet
printer. The scanner has one of the square 4-pin USB connectors, and the
cable is the flat 4-pin to square 4-pin ones.

Power supply "brick" is providing correct voltage.

Ideas?

Thanks,
