CHAPTER 2 BASIC OPERATION
· Counting Originals
The number of times that the registration
sensor has turned on in response to the trailing
edge of an original is used as the number of
originals.
The ADF is not equipped with an original
feed mode for counting originals when making
double-sided copies of single-sided originals.
The originals are copied in order of how they
are picked up and delivered accordingly.
