The original is fed by the ADF entrance roller [A] and the pre-scanning (front side) roller [B],
scanned on the exposure glass under the scanning guide plate (front side) [C], and then
delivered by the pre-scanning (rear side) roller [D].
The feeding of the original is detected by registration sensor (S24) [E]. If an error occurs, it is
reported as a paper jam.
The original is fed by the pre-scanning (rear side) roller [D], scanned by the CIS (S21) [F] on the
scanning guide plate (rear side) [G], and then fed out by the exit roller [H].
When the original passes through the ADF entrance roller [A], the original feed sensor (S25) [B]
is detected OFF. If the next original is set, the original set sensor (S22) [F] detects ON and the
original feed clutch (CL4) [C] is turned ON. Then, the feed roller [D] and pick-up roller [E] rotate
