I just purchased a MacBookPro 17" and moved my Epson 1670 optimistically to the new laptop.
I HAVE THE IDENTICAL PROBLEM (a blank/white document as the scanned image)! Epson has been less than useless (so far).
On the Epson website the following (similar, but not exact problem) FAQ is answered. I cannot understand what they mean. Does anyone have any understanding or, better yet, a solution to this problem.

Q:
I just installed the Epson Scan software for Mac OS X 10.4.x, but it will not run. It just pops up in the Dock and then disappears. What should I do?
A:
If you're using a Power PC or Intel-based Mac with OS X 10.4.x, your hard drive may be partitioned for Mac OS Extended (Case-sensitive/Journaled) or Unix File System. These formats are not supported. You will need to use Mac OS Extended or Mac OS Extended (Journaled) when formatting the partition.
