The cartridge location spring pushes the ribbon cartridge to the CS drive lever via the cartridge location pin
to lock the ribbon cartridge. A color section of the color ribbon is selected by moving the motor to
the color ribbon position using point as a start point (color home position: black ribbon
Figure 2-7 a). At this time, the color home position is detected by the CS sensor.
When the black ribbon cartridge is mounted at the carriage, the projection the carriage prevents the
bottom face of the ribbon cartridge from touching the CS driver lever.
As a result, the drive lever going up or down never touches the bottom face of the black ribbon cartridge,
and the color selection mechanism is functionally canceled. (See Figure 2-7 b).).
