2.6.2 PAPER FEED MECHANISM
The pick-up roller [A] and paper feed roller [B] are driven by the main motor [C]
through gears and a timing belt.
During the printing cycle, when the feed start timing sensor [D] is actuated by the
actuator on the drum, the paper feed clutch [E] is energized to transmit the main
motor rotation to the paper feed roller shaft. The top sheet of the paper is
separated from the paper stack by the friction between the roller and the friction
pad (not shown), and is then transported to the registration 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 the paper transportation.
