1.2 Carriage Function

The carriage of this printer is moved back and forth horizontally by the carriage belt,
which is driven by the carriage motor, a DC motor.
This printer has no sensor to detect the carriage's home position. The encoder sensor,
mounted on the carriage board, enables control of the carriage position by reading data
from the encoder film, assuming the initial position being where the carriage contacts
the right hand interior wall of the printer.
