good day, probably you have to update for a new driver to work whit windows 7.

Hi rachellmaldo,

Please try to download these DRIVERS for your EPSON scanner.

Hope this helps.

The driver is classed as inbox. An inbox driver is already installed and should install automatically when the printer is connected and powered on. This if the printer driver. You will also need the scanner driver which epson say the Vista version is compatible and can be downloaded from their website.

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. Install the drivers 3. In Start Menu->All Programs->Accessories right-click Notepad and select Run as administrator 4. In Notepad File->Open and browse for the es27.inf file located in C:\Program Files (x86)\epson\escndv\es0027 5. On line 51, 54, and 57 replace PID_011B with PID_0101 6. Save the file. 7. Connect and turn on the scanner. 8. In Device Manager (Start Menu, right-click Computer, select Properties, Device Manager) right-click the scanner and select Update Driver Software->Browse my computer for driver software 9. Select the location of the modified INF file (C:\Program Files (x86)\epson\escndv\es0027 Include subfolders checked). 10. Say ok to the window that pops up and it should start installing the drivers.
In Photoshop you should then be able to import using WIA-Epson Perfection 2400 (importing with Epson Perfection 2400 causes Photoshop to freeze)
I hope that works for you :)

I switched off the power, then I disconnected the lid from the base, put the power back on, the green light came on & then I reconnected the lid to the base & it has been working fine ever since
