2.1.5 Ribbon Feed and
The RF motor supplies power to both the ribbon feed and tractor select mechanisms. The rotaticm
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.
Figure 2-11 shows the ribbon feed mechanism. 7he ribbon is fed in only one direction.
Counterclockwise rotatkm of the RF motor is transmitted to the ribbon feed gear through the
ribbon &d select gear and ribbon feed transmission gear. The ribbon feed gear engages the
winding roller on the ribbon cartridge to feed the ribbon.
