Adobe Photoshop CS5 does not recognise my scanner/All-In-One in Mac OS X. What should I do?
Mac OS X.
Adobe Photoshop CS5.
Scanning functionality - importing to Photoshop.
Epson Scanner & All-In-One ranges.
Adobe Photoshop CS5 no longer automatically installs the TWAIN plug-in it needs to recognise your scanner. Instead, the TWAIN plug-in is available via download from Adobe. Follow these steps to manually install the TWAIN plug-in:
Quit Photoshop CS5.
Download the optional Mac OS TWAIN plug-in from Adobe and read the accompanying support information. Adobe has made it available via the following TechNote article on the official Adobe website.
This information is provided as is. Epson is not responsible for the content of third-party websites and the information may change without notice.
Copy the TWAIN plug-in file to the Adobe Photoshop CS4\Plug-ins\Import-Export folder on your Mac OS X hard disk.
Restart Photoshop to enable the plug-in.
We recommend using Photoshop in 32-bit mode as you must have a 64-bit version of the scanner driver to use the scanner in 64-bit Photoshop. If your Epson scanner does not have a 64-bit drivers available, run Photoshop in 32-bit mode in order to import the scanner.
