2.3 ORIGINAL TRANSPORT AND EXIT MECHANISM
2.3.1 Single-sided Original
[A]
[B]
[C]
[D]
When the leading edge of the original reaches the registration sensor [A], the
DF feed and transport motor will turn off. After a short delay, the DF feed and
transport motors will turn on again. The original is fed across the DF
exposure glass [B] and it is scanned in this area.
The original is fed through to the 2nd transport roller [C] and fed out by the
exit roller [D].
The DF feed motor speed while feeding the original to the registration sensor
is 59.4 mm/s. However, when the motor turns on again to feed the original to
the exposure glass, the speed will depend on the selected reproduction ratio.
At 100%, it is 90 mm/s.
