The file size is too 
large.
The size of the file will depend upon 
many factors. The physical size of the 
document and the amount of text / 
graphics on each page are factors that 
will affect the resulting file size. These 
factors cannot be changed.
To produce the smallest scan file for a given docu-
ment, use the lowest resolution and Black and 
White mode, and scan the smallest area possible. 
Using the opposite settings (scanned in the highest 
resolution, in the Color mode, and scanning the 
largest area possible) will produce the largest-sized 
file.
