Scanner Pulls Extra Page, Keeps Asking for Next Page

I have an Epson Perfection 3170 scanner with an automatic document feeder.

I'm running OS X 10.5.5 on a PowerMac G4 FW800 (2x1.25mhz processor).

I'm running into two issues when using the scanner with Acrobat Professional 7.0:

1. After each sheet goes through, the feeder automatically runs another page through (but does not scan it).

2. I need to turn off the "Next Page" pop-up. What's the point of having a document feeder if you need to verify scanning after every page?

At one point, I did install the sane-TWAIN drivers. I assume this is related. I have totally removed that software (from the OS X side and through the terminal).

Additionally, I have tried:
-Reinstalling OS X
-Reinstalling Acrobat / CS2
-Reinstalling the Epson drivers
-Scanning with single/double-sided scanning
-Trying with/without OCR activated
-Running with the ADF (auto document feeder) option on, and "auto detect" turned on

Any fixes or helpful suggestions would be GREATLY appreciated.
