Original reversal and conveyance
control
The original exit gate which switches the
original exit path is driven by SD302 (exit
gate drive). The reverse gate, which
switches the original feed path during
double-side original copy mode, is driven by
SD301 (reverse gate drive). SD303
(pressure roller release) releases the
pressure on the original exit reversal roller.
Ejection of the original and conveyance to
the reversal exit are performed by M302
(original conveyance), which rotates the
conveyance roller and original exit roller.
M301 (original feed) drives the reversal roller
