Make sure of the following notes when Cut Mode is "Standard"
A copy length is always equal to an acquired standard size.
Adding and reducing a trailing edge extends a part of the image out of the paper.
The excess part will be removed, and the range at which the image is placed originally will
be a blank.
If you specify both leading edge and trailing edge with selecting "Standard Cut", only the
leading edge will be applied. (trailing edge is ignored.)
Relationship between magnification and leading/trailing edge.
