Operating Principles
If the paper in the printer becomes bubbled, you can pull the tractor wire to the
right to stabilize the paper tension between the left and right tractor sprockets.

Ribbon Feed and Tractor Select Mechanisms

The RF motor supplies power to both the ribbon feed and tractor select
mechanisms. The rotation of the RF motor pinion swings the ribbon feed select
gear like a pendulum, using the lever axis as a support point. The rotation of the
RF motor is transmitted after the gears are engaged. When the RF motor pinion
gear rotates counterclockwise, the motor rotates the ribbon feed mechanism; when
it rotates clockwise, the motor rotates the tractor select mechanism.
