2.2.04 Paper Feed Mechanism
Paper feeding is performed by turning the platen and the tractors, which are driven by the line feed pulse
motor.
The paper feed mechanism consists of the items listed below.
Line Feed (Pulse) Motor with gears
Idle Gear
Change Spring
Change Gear
Platen
Push Tractor Assembly
Bottom Tractor Feed Unit
Paper Pressure Guide
Friction (Sheet) Feed
When the release lever is set to the SHEET FEED position, the change gear is disengaged from the
tractor gear. At the same time, the release lever applies pressure to push the pressure rollers against the
platen, allowing paper to be fed.
A photosensor located in the paper pressure guide detects PAPER END.
Tractor (Continuous) Feed
When the Release Lever is set to the TRACTOR FEED position, the release lever allows the reset spring
to push the change gear toward the tractor gear. At the same time, the release lever pushes the pressure
rollers away from the platen, allowing paper to be fed by the tractors.
The microswitch on the push tractor (rear feed) and the paper end sensor on the sensor board (bottom
feed) detect PAPER END.
