Power transmission route and motor rotational direction
The rotation torque of the paper feed motor is transmitted via the PF roller gear L and paper feed
roller to the PF roller gear R which always meshes with the clutch gear, as described in Section
3.2.2.2, [ 4 ].
The clutch gear also meshes with the SF changeover gear, HS changeover gear, or purge gear when
the mode switching lever is in the leftmost position, 2nd position from the left, or right position,
thereby switching the operation mode to the normal SF, high-speed feed, or purge mode,
respectively.
