This problem arises when the user has been scanning multiple large documents using the assisted scan feature. This can be resolved by rebooting the pc and clearing the cache that has built up as this program never technically closes and emptys. It is also possible to fix it by changing the dpi that it scans at to 600dpi and setting the color selection to automatic and not using the assisted scan portion.
