Direction
 The two-dimensional VCSEL array of laser diodes allows precise
control of image reproduction.
 If the MUSIC sensors detect that lines across the image are bent
as shown above, the machine can adjust the image signals that
are sent to each of the 40 lasers. This reconstructs the image that
would be printed if there was no bow skew.
 Without this adjustment, color registration errors may be
observed.
