Scanner Movement for Two-Page Separation Mode (copy
count "2")
Figure 3-303
Timing of operations, i.e., 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 (220V, or 240V copier) 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.
