For I, II, and III shown in Figure 3-305, control is with reference to the leading edge
of the 1st original (falling edge of PS1).
I: The distance from the leading edge of an original over which the scanner moves is
determined by the selected reproduction ratio and cassette size as in the case of
normal copying.
II: More or less the same as I; however, if the distance over which the scanner travels
is longer than 210mm/8.5", 210mm/8.5" will be used as the leading edge of the 2nd
original.
If it is shorter than 210mm/8.5", the point at which the scanner reverses in I will be
used as the leading edge of the 2nd original.
III: The same as I.
