2.3.5 PAPER FEED
This section describes the paper-feed operation.
2.3.5.1 Paper-Feed Mechanism Operation
The paper-feed mechanism operates by friction feed for cut sheets and by the push tractor feed method
for fanfold paper.

Friction-Feed Operation

The paper is held against the platen by two paper-feed rollers and by the printer cover. The paper-feed motor
is driven to rotate the platen gear, via the paper-feed reduction gear, in the direction shown in Figure 2-58.
The rotation of the platen gear feeds the paper in the direction of the arrow, as a result of friction from the
paper-feed rollers and platen. Because the paper is held against the platen by the spring force of the paper-
feed rollers, the paper can be released by shifting the paper-release lever forward.
