surface detection level difference 1 to 255 255
G: Set value (color) of the developing
basis correction start voltage difference
in high density image correction 0 to 255 50
H: Set value (black) of the developing
basis correction start voltage difference
in high density image correction 0 to 255 75
I: Patch forming developing bias

detection level difference 1 to 255 29
O: Adjustment target value (Color
image density sensor) when adjusting
the primary LED current value by using
the calibration plate in SIM44-36. 1 to 255 110
P: In SIM44-36, the toner patch density
is read by three kinds of LED currents
with the primary LED current
adjustment value as the center value in
order to obtain PCS C LED ADJ value.
This is the deflection range of the
current value in the above case. 1 to 255 10
