SPDF
The original is fed by the SPDF 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 the SPDF registration sensor (S16) [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 SPDF CIS [F] on
the scanning guide plate (rear side) [G], and then fed out by the exit roller [H].
When the original passes through the SPDF entrance roller [A], the SPDF feed sensor (S17) [B]
is detected OFF. If the next original is set, the original set sensor (S14) [F] detects ON and the
SPDF feed clutch (CL8) [C] is turned ON. Then, the feed roller [D] and pick-up roller [E] rotate to
pick up the next original.
