Push-Pull Tractor Method
This method is a combination of the above-mentioned push tractor method and the pull tractor method.
The push tractor pushes the paper toward the
printhead, while the pull tractor pulls the paper from
the
printhead. This provides more accuracy in paper feeding operation.
Figure 2-11 shows the push-pull tractor method from the rear feeding slot.

2.1.3.2 Release Lever Operation
The friction feed method and the tractor feed method can be switched to each other with the release
lever (LEVER, RELEASE, MAIN). When the release lever is set to the Friction Feed position, the paper
feed rollers are made to contact the platen. When the lever is set to the Tractor position, on the other
hand, the paper feed rollers are set free from the platen. The position of the release lever is detected
by the Release Sensor (CONNECTOR SWITCH).
