4.2 PAPER FEED ROLLER MECHANISM

[C]

[A]
[E]
[B]
The paper feed roller [A] is driven by the main motor [B] through gears and a
timing belt.
During the printing cycle, when the feed start timing sensor [C] is actuated by
the actuator on the drum, the electromagnetic clutch [D] is energized to
transmit the main motor rotation to the paper feed roller shaft. The top sheet
of paper is separated from the paper stack by the friction between the feed
roller [A] and the friction pad [E], and is transported to the 2nd feed roller.
A one-way clutch is installed in the paper feed roller so that after the
electromagnetic clutch is de-energized, it does not disturb paper
transportation.
