‰

There are two laser diode units (LD units); one is for K and 
C, and the other is for M and Y.

Š

Each LD unit produces laser beams for two colors.

‰

There is one laser beam for each color.

The two laser diode units are physically the same. However, don’t switch them 
because the color skew adjustments for each color could be different.
