Epson has not released a printer driver for Win 7 and this printer.

My system locks up when I attempt to download images from my PDC 640 camera.

While it appears that the system is locking up, the actual problem is that a message prompt in the PhotoMAX 2.0 software is hiding beneath other open windows and needs to be answered before proceeding. In this instance, the PDC 640 TWAIN Driver window has been preset to always be the "top" window, obscuring any other windows that may be open behind it. The PhotoMAX 2.0 window must be "active" (or "brought to the top") to answer any message prompts. Once the message prompt is answered, you will be able to download images. To deactivate the PDC 640 TWAIN Driver window's "Always on Top" preset: 1. Launch the PhotoMAX application. 2. Select Get Photo. 3. Select Camera or Scanner. The Acquire From window appears. 4. Select Twain device and click OK. The Select Source window appears. 5. Highlight PDC 640 and click Select. The album window appears next, followed by the PDC 640 TWAIN Driver window. 6. Right-click on the PDC 640 TWAIN Driver window and deselect (i.e. uncheck) "Always on Top". To move the PhotoMAX 2.0 window forward: 1. Launch the PhotoMAX application. 2. Click on Get Photo. 3. Click on From Album. 4. When the album opens, answer YES to the question "The contents of this album have been changed. Do you want to save the changes?". 5. Click on the Acquire icon at the top of the album window to select the PDC 640 camera and download the thumbnails from the camera. Your system will no longer appear to lock up.
