Calibration is preset and should not be changed.

Decimal 27 126 87 nl nh m
Where
n = The offset adjustment of the Black dot in n/203 inches where n =
nl + 256*nh. Default is 304 or 1.5 inches. Values greater than 368 will set
n to 368.
m = The Width of the black dot in m/203 inches. The default is 76 or
0.375 inches. Values less than 51 will be ignored.
The offset adjustment is the position of the black dot in relation to the cut point. If n = 0
the cut point will be in the center of the black dot. If the value of n = 304, the cut point
will be 1.5 inches above the black dot.
Note: This command may be issued as part of an application. If the
values in the configuration match the requested values, no operation
occurs.
