Push Tractor Feed Operation
When the push tractor unit is used, the paper is
the tractor belt. The paper feed motor is driven and, via the pinion on the motor shaft, rotates the gears
in the direction shown in Figure 2-39, rotating the tractor belts. This causes the paper advances in the
direction indicated by the arrow. When push tractor feeding is used, the pressure of the paper feed
rollers against the platen is released by moving the paper release lever to its forward setting.
