G'morning!
Hardy, I came very close to downloading the wrong driver because the paperwork inside the scanner box was for the 2400 - I realized at the last minute that something didn't sound right and got the correct one.
Geoffrey, oh boy. I think that you have given me something to try and a heads-up to the reason it hasn't worked thus far. The link to the driver you gave is the very one that
MUSTEK had me download. The driver that
ADOBE had me download was here: (I hope but if the link doesn't work the name of the dmg is in it)

In the file structure for PSe8, the folder Plug-Ins has 10 sub-folders. OK. The twain.plugin that came with the original installation of the PSe8 program was placed in a sub-folder called Import Modules (where it remains). The twain.plugin that I downloaded per MUSTEK's instructions, the same one you used, was placed at their instruction in a sub-folder called Extensions. The
third twain.plugin (can you believe it?) that ADOBE had me download was placed at their instruction in a sub-folder called File Formats.
The one thing ADOBE had me do that Mustek did not, was to add the folder pointer under Preferences/Plug-Ins in PSe8.
The documentation that came with the package you used, and that MUSTEK recommended directs the plug-in to be placed in Import-Export. That sounds similar to the folder called Import Modules, where the program's own pre-installed plug-in resides.
I hope this is clearer than my own confusion makes it seem to me (keeping all the variations straight is making me dizzy). I am going to try to use the plug-in you are using, place it in the Extensions sub-folder that MUSTEK wanted and then add the folder pointer in preferences. I don't think I'm knowledgeable enough at this point to try replacing the program's original plug-in with the legacy version. I just don't know what other implications that would have.
Of course, I could use all this as the perfect excuse to treat myself to an upgrade to Photoshop. 🙂
I really appreciate the input you all have given me, and your patience with a newbie. While I do want the scanner to work, I am very much enjoying this as an opportunity to learn more about my Mac and how it works. A week ago I had no idea of "TWAIN" and laughed at the "Technology Without An Informative Name" and other versions. If I get something to work, I'll post the specifics of what went where to make it happen.
Thanks! MJ
