2.2.5 Paper Feed Mechanism

The paper feed mechanism is composed of the paper feed motor, platen, push tractor unit, paper tension
unit, and release mechanism. Either the friction feed or tractor feed system can be selected depending
on the paper used. (There are two paper entrances. One is for friction feed and the other is for tractor
feed.) Rotational movement of the paper feed motor is conveyed to the platen in the case of friction
feed, and to the push tractor unit (the platen also rotates) in the case of tractor feed. The conveyance
mechanisms are switched using the release lever. The paper tension unit is mounted at the top of the
platen, and is rotated by the paper feed motor. The paper ejection is assisted by friction between the
platen and the paper tension unit.
