The image size is 204 MB if I didn't make a mistake. However, it
doesn't look like as if any of the programs buffers the whole image.
When I try that with the test backend, I don't have any problems and
the meomory usage is low. Maybe you can try the test backend also 
(-d test) to find out if it's a problem with the epson backend.

I tried:

scanimage -d test --resolution 1600 --mode color -x 400 -y 400 |cjpeg
-quality 85 >picture.jpg

--quality=85 doesn't seem to be recognised by my version so maybe we
have different versions:

Ok, pretty old :-)
