6.8.2 PAPER FEED MECHANISM
The paper feed motor [B] drives the paper pick-up roller [C] and the paper feed
roller [A]. There is a one-way clutch in the paper feed roller. When the roller stops
and paper is fed by the registration rollers, the one-way clutch ensures that the
paper feed roller does not resist the paper feed.
To prevent a paper misfeed, the feed speeds are changed to match the printing
speed.
Since paper feed timing must be synchronized with pressure cylinder rotation (so
that the paper clamper on the pressure cylinder can catch paper’s leading edge
accurately), the paper feed motor on timing is maintained by the feed start sensor
[D].
A short time after the pressure cylinder [F] starts rotating, the actuator [E] on the
rear of the pressure cylinder activates the sensor.
