When the leading edge of the original reaches the registration sensor [A], the
DF feed motor turns off. After a short time the DF feed motor turns on again.
The original is fed to 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 of the DF
unit by the exit roller [D].
The DF feed motor speed while feeding the original to the registration sensor
is 47.5 mm/s. However, when the motor turns on the second time to feed the
original to the exposure glass, the speed depends on the selected
reproduction ratio. At 100%, it is 90 mm/s.
