Figure 3-16
Timing of operations, I, II, and III shown
in figure 3-16 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.
Ill:
Same as I,
