Rotates the mirror position motors (CMY) by 250 pulses clockwise; then by 125
pulses counterclockwise. This moves the mirrors back to the initial position. Then, the
settings of SP2-908-002 to 004 are reset to 0.
When the line position adjustment fails, it is one of possible causes when the mirror
position motor locks. Performing this SP mode can move the mirrors back to the
original position if it locks. Then, do the forced line position adjustment (SP5-993-
002).
