The microprocessor
on the DC controller
controls the distance
over which the scanner
moves
based on the falling edge of the scanner home position signal. Although the distance differs depend-
ing on the length of the copy paper'
and ratio of reproduction,
the scanner is moved forward
for
A4-size
paper (297
mm) at least.
* For detection of the length, see p. 3-26.
