1) Before driving the drum,
the calibration plate is
opened with the
process control BK
sensor, and light is
emitted with the gain
value of 0 and with the
light emitting quantity
fixed to 120. The
average of ten light
quantities repeats to be
5 or less for 3 times
continuously.

driving the drum, the
calibration plate is
opened with the
process control BK
sensor, and one whole
turn of the belt surface
is scanned with the gain
value of 0 and with the
light emitting quantity at
the optimum value (120
– 50). The difference
between the max. value
and the min. value of
