Function and [Setting]
Displays the current LD unit position (number of
pulses from home position). If this is different
from the value of SP2109-01 or SP2109-02, LD
unit positioning has failed.
Displays how many times the LD unit position
has been changed (how many times the
resolution has changed.)
When the laser beam pitch adjustment is done,
this counter is reset to zero.
Resets the values of SP2109-06 and SP2109-
07.
After replacing the LD unit, this SP mode must
be performed. See section 3.9.5.
Sets the scanning resolution (dpi).

enters the energy saver mode, the polygon
motor will ignore the zero setting and switch
itself off.
