11. Bypass feed clutch
This is a spring-type mechanical one-way clutch used to transmit the drive from the main motor (M3)
to the bypass feed roller and bypass pickup roller. When the bypass pickup solenoid (SOL2) is
turned OFF, the spring tension of the one-way clutch decreases to cut off the drive.
12.Registration roller
Paper transported from the pickup roller or bypass feed roller is pushed against the registration
roller which aligns the leading edge of the paper. Then, the registration rollers rotate to transport the
paper to the transfer position.
13.Registration clutch (CLT1)
This is an electromagnetic clutch which drives the registration roller. When the registration clutch
(CLT1) is turned ON, the drive is transmitted from the main motor (M3) to rotate the registration
roller.
14.Registration sensor (S4)
It is used to detect that the leading edge of the paper has reached the registration roller and to
control the aligning amount of the paper (the amount of the paper bend before it is transported to the
registration roller). Also, it is used to detect the trailing edge of the paper has passed the registration
roller.
15.Drawer detection sensor (SW5)
The switch to detect whether the drawer is fully inserted or not.
