221 Transfer Transfer transformer DC
output adjustment (C)
ALL 138
<0-255>
M When the value
increases, the transfer
transformer output
increases. The output
value of the transfer belt
power supply roller is
unmeasurable since its
voltage is extremely
high.
* Make sure to close
the front cover when
this code is used.
Never touch the high-
voltage section.
* This selection is dis-
abled when the
developer unit is not
installed.
