2.1.4 Paper Loading/Feeding Mechanism

The following stepping motor controls the Paper loading/feeding mechanism on these
printers.

The drive of the PF motor is transmitted to the LD roller shaft and the PF roller through
gears for the Paper loading/feeding mechanism. The Paper loading mechanism plays a
role in loading a paper from the ASF unit to the PF roller. And also, the Paper feeding
mechanism plays a role in feeding a paper loaded from the ASF unit. The functions of
the Paper loading/feeding mechanism varies depending on the rotational direction of
the PF motor as the table below.

*2

: The PF motor rotation direction = seen from the left side of the printer.

Following shows you the transmission path of the PF motor drive to the LD roller, the
PF roller and the Paper eject roller. (The numbers in the following figure show you the
order of transmission path.)

Note: The Clutch gear is molded on the backside of the Spur gear 35.2 such as Combination gear.
