How To Get Epson 636U Working In Windows 7/64

I've had my Epson 636U scanner for many years, and looking at the reviews of current flatbeds, none seem to be holding up as well as this. I was a bit reluctant to gut my machine and move from XPPro/SP3 to Win7/64, but with some judicious digging around, I was able to find the process to get it working. Tried this on my testbed system and it works.

I got mine working on Windows 7 (x64) by doing the following:

1. Download the Windows 7 Epson Scan driver for the Perfection 2400 from the
epson site

2. Allow the drivers to unzip, but cancel the install. You should have an EPSON directory created.

3. In Notepad File->Open and browse for the es27.inf files in the EPSON directory as well as subdirs

4. On line 51, 54, and 57 replace PID_011B with PID_0101

5. Save the files.

6. Run Setup.exe from the Epson directory and select the 2400. Say ok to the window that pops up and it should start installing the drivers.

7. Connect and turn on the scanner.

8. You're done!

In Photoshop you should then be able to import using WIA-Epson Perfection 2400
(importing with Epson Perfection 2400 causes Photoshop to freeze)
