The machine automatically calculates the correct copy (zoom) ratio based on the values you
entered; however, the original image may be cut off slightly depending on the paper size.
If the computation results in a copy ratio greater than 200%, place your original on the platen
glass.
If the computation results in a zoom ratio less than 25% or greater than 400%, a message
appears telling you that values below 25% will be set to 25%, and values above 400% will be
set to 400%.
