Maybe a memory problem with your system. Or with MS photo Editor.
Make sure you have enough HD space and your virtual memory setting is large
enough. Virtual memory is HD space.
Most scanners must have at least 64 Megabytes of ram in the computer. If
part of the 64 MB is shared with video, then you do not have 64 MB of ram
for programs.
The amount of virtual memory need for a 8.5 inch by 11 inch scan at 1200
dpi, which you should never need (Flat stuff, no more that 600 DPI) is:
8.5 inches X 1200dpi = 10200 pixels
11 inches X 1200dpi = 13200 pixels
10200 X 13200 = 134,640,000 pixels.
Each pixel is about one byte. (256 levels fits in one byte)
So that is 134,640,000 bytes of space for an 8 bit gray scan of 8.5 X 11 at
1200DPI.
Scan one image then save that image. Close the twain interface (to clear the
temp memory usage). Open twain then scan another. You may have to close the
photo editor also.
In short you need more horsepower. More ram, more hard drive and faster CPU.
