b. Control of the paper feed roller
The paper feed roller is controlled by the paper feed motor
(M301).
When the paper feed motor rotates in the forward direction,
the drive force is transmitted to the paper feed roller and the
feed roller via the paper feed drive shaft, causing pre-paper
feed to take place.
c. Control of the registration roller
The resistration roller is controlled by the paper feed roller
(M301). When pre-paper feed takes place, the paper feed
roller rotates in reverse, and the drive force is transmitted to
the resistration drive roller and the registration driven roller
via the resistration drive roller shaft, causing paper feed to
take place.
