Carrier drive mechanism

The carrier transport motor controls horizontal motion. The motor rotation is transmitted via the
motor pulley to the timing belt.
The carrier, which is supported and guided by the main shaft, is secured to the timing belt.
Clockwise and counterclockwise rotations of the carrier transport motor move the carrier to the
right and left, respectively.
On the back of the carrier is the carrier home position sensor (photointerrupter) which tells the
control circuitry whether the carrier is in the home position.
