138 M When the value
<0-255> 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.
55 M A relative humidity
<0-99> detected at the image
quality closed-loop con-
trol is displayed.
0 M 0: Normal
<0-2> 1: Error (control stopped)
2: Error (sensor abnor-
mality)
0 M The drum surface poten-
<0-999> tial of the main charger
center bias measured by
the sensor is displayed.
60 M The humidity of the

surface potential sensor
control is displayed.
0 M The measured value of

discharging is displayed.
50 M The lower limit bit value
<0-255> of the main charger grid
control voltage is output.
207 M The upper limit bit value
<0-255> of the main charger grid
control voltage is output.
59 M The lower limit bit value
<0-255> of the developer bias

227 M The upper limit bit value
<0-255> of the developer bias
control voltage is output.
