..1)Has any tried to use a scanner to pick up the projected image
..instead of
..using photographic paper? Potential problems?
If you are thinking of color images the color balance of the lamp in the
scanner is NOT daylight. It has a lot of blue and small amounts of red. If
you are projecting an image you will need to watch the intensity and
hopefully have a good IR cut filter. You will also need to limit the
intensity if using a projector bulb.
I tried to scan behind an 8 X 10 lens. Only imaged close to the center of
the lens. Needed to have ground glass but was concerned , as you are, with
the lamp.

..2) Any suggestions on how to turn off the light source inside the
..scanner,
..and also then turning it back on for regular scanning?
This may cause many problems. One of the things a scanner may do is a
"white" calibration just before moving onto the image area. With the lamp
off the software may move the color control to who knows where and the gains
will be cranked up...if it scans at all. To turn the lamp on and off just
cut the wire feeding it and put in a switch. Wait for the calibration phase
and then switch it off as it starts into the image area. But color balance
is going to be a problem because CCD's see IR well, red well, green OK and
in the blue arena they need help. While PhotoShop can balance colors it can
not add information that you should of scanned in if you had more blue
sensitivity or blue light.

..3) Any suggestions on a used scanner that would better suit this project?
Try and get a free one to make mistakes on.
