Paper feeding operation
(See Fig. 2-11)
Paper is feed while the paper feed drive gear assem-
bly performs one rotation. When the paper feeding
gear series (see Subsection 2.2.1,
Transmission/
Select Mechanism) causes the paper feed gear to
rotate in the direction of
➡
arrow (1), the paper feed
roller within the platen also rotates in the direction of
➡
arrow (2), and the paper is fed by friction between
the paper hold roller and the paper feed roller.

When the paper feed ratchet within the paper feed drive
gear assembly strikes the return lever, it disengages
from the paper feed ratchet wheel, the rotation of the
paper feed drive gear assembly stops, and paper
feeding terminates.
