6. REVERSAL SECTION
B. Large size original
A specified period of time after the start of the conveyance [1] of the 1st original, the front of the 1st original is
read [2]. The 1st original conveyed to the reverse section stops temporarily after being accelerated by the origi-
nal paper exit motor /2 (M305) and the original paper exit motor /1 (M304). M305 and M304 start a reverse rota-
tion [3] to let the original hit against the conveyance roller for registration. For the back of the original that has
been registered, a specified period of time after the original reverse sensor (PS309) turns ON, the pressure roller
release solenoid (SD302) is turned ON [4] to release the pressure roller, and then release the conveyance force of
the reverse section. A specified period of time after the original conveyance sensor (PS308) turns ON [5], the
back of the 1st original is read [6].
