3.2.2 Printing Mechanism
3.2.2.1 Paper pulling-in, registration, feeding and ejecting mechanisms
These mechanisms are driven by a single paper feed motor located at the left of the engine unit via
a gear train. (See the illustration on the next page.)
The following illustration is a cross-sectional view of the machine viewed from the right. Place the
recording paper face down in the recording paper tray. This paper first proceeds to the rear, bends
upward, heads back toward the front panel, passes under the head/carriage unit for printing, and
finally enters the eject tray on top of the recording paper tray.
