Original Transport And Exit Mechanism - Ricoh B121 Service Manual

2.3 ORIGINAL TRANSPORT AND EXIT MECHANISM

[A]
When the leading edge of the original reaches the registration sensor at [A], the DF
transport motor turns off. After a short time the DF transport motor turns on again.
The original is fed past the DF exposure glass [B], where it is scanned. It is then
fed through to the 2nd transport roller [C] and fed out by the exit roller [D].
The DF transport motor uses a constant speed to feed the original up to the
registration sensor. When the motor turns on again to feed the original to the DF
exposure glass, however, the speed depends on the selected reproduction ratio. At
100%, the speed is 89 mm/s.
