"The picture quality is somewhat fuzzy, that could 
be it, I know that my digital camera does that to 
my pictures, and using the camera is smarter than 
a hot flatbed scanned which warms the cel and 
expose it to high light."

Actually, all cels go through some temperature and 
humidity variation, and a scanner bed is hardly 
the top end of it. (Ugh, a cel shop in Tokyo was 
incredibly hot and humid, but the cels seemed ok) 
Also, it isn't only the intensity of the light 
that damages cel lines, it's mostly the length of 
time a cel remains in ANY light (even low light) 
that would damage it. Assuming the scanner is 
decent enough (mine is one of the fastest 
mid-range ones), the time the cel is on a scanner 
bed is most likely not enough to permanently 
damage it ..
