I've been using CS3 for a few years (on a Mac platform). I just got a new computer (OS 10.7.5), but can't get scans imported successfully. I downloaded the latest driver from the Epson website (my scanner is an Epson Perfecion 3200 Photo), but instead of going into Photoshop as directed, the data wound up in an otherwise blank window. I repeated this for someone at Epson Tech Support, and he said it was a Photoshop issue. Normally, accessing the scanner involved Photoshop --> file --> import, but right now my scanner doesn't show up on the sub-menu, nor do I know how to get it there! Can anyone help? Thanks VERY much. Hart 100.
The TWAIN plug-in support has been dropped from recent versions of Photoshop.
Did you update to CS6 perhaps?
Also, make sure you have a fresh, updated, Lion-compatible scanner driver from Epson.
Anyway, scanning from the Import menu item inside Photoshop is a very inefficient way to scan. Photoshop does not do the scanning anyway, and you're just tying up the very expensive Photoshop application for no good reason whatsoever. The TWAIN Import menu item only calls on your scanner application to do the scanning for you but otherwise blocks you from using Photoshop simultaneously.
By all means scan outside of Photoshop, either with your scanner's stand-alone scanning application or a utility like VueScan or $ilverfa$t (Silverfast). VueScan even will put up a menu item under Import, but will let you use Photoshopon something else while you scan.
Scanning outside of Photoshop lets you continue working on other stuff while you scan.
Thanks for clarifying, Chris.
It's not clear to me what version of Photoshop the OP has, maybe he's still on CS3, as he says.
Also, he says he's on 10.7.5. Would the Image capture bug bite him there too?
