Hardware :: Connecting Old Epson Scanner With Updated Drivers

I reattached my Epson Perfection 1650 Photo scanner to my Mac G4 (Sawtooth) desktop today after updating the drivers and all to OS 10.4, which is what is on my computer. (The updated drivers also work for 10.5, which is on my laptop, but that doesn't matter here.) When I hit the Smart Panel icon on the desktop, the computer went to Classic mode, for some reason, even though the updated software is for OS X. I was able to get a Twain window, but when I clicked on any of the options for scanning, I get a message saying that the scanner is not recognized (something about a bus). I looked at all the available FAQs at the Epson Web site, but they are not helpful or relevant. For example, one told me to turn off Scan Monitor in Extensions, but of course, there is no Extensions Folder in OS X. One other FAQ suggested reinstalling the software that came with the scanner, but that was way back when I used OS 9.2.2, so how could I then bring it up to 10.4?

Most of the other FAQs were for people with Windows, so of course, those didn't help at all. The Ready light is on; all the cables are plugged in properly. I'm ready, willing, and able. I can't get Epson support, because the scanner is out of warranty, and the Epson online helpers (private) want a good deal of money to provide an answer. Granted, I don't have to pay them unless I am not satisfied with the answer, but I'd rather not have to sell the farm, when I could get a new scanner for only about twice what they are asking to give me an answer. OR (breathlessly hoping) if I can get some ideas here. I have a lot of pages to copy and send to someone, and now I'll have to copy them manually at the local store or across town, at my mother's, and then send them through the mail. It all seemed so straightforward and simple: scan and send to the eager recipient.
