The timing of operations, I, II, and III shown in Figure 3-304 is with reference to the leading
edge of the first page of the document (fall of Q3 signal).
I: The distance traveled by the scanner from the leading edge of the original is determined by the
reproduction ratio and the copy paper size, just as for a normal copy.
II: This is roughly the same as I. If the forward distance traveled by the scanner is greater than 210
mm the DC controller will judge that 210 mm is the leading edge of the original. If the distance
that the scanner moves forward is less than 210 mm, the point at which the scanner reverses in
I will be the leading edge of the second page of the document.
III: Same as I.
