Displays the output value of image
quality sensor when a low-density
test pattern is written.
The larger the value is, the smaller
the toner amount adhered becomes.
The LED light amount adjustment
value of this sensor is the reference
value to set the reflected light from
the belt surface.
Displays the relative humidity at the
latest performing of the closed-loop
control.
Performs the image quality open-loop
control.
Performs the image quality closed-
loop control.
Performs the image quality control,
initialize each control value.
Sets the target value of high image
density control at the time of the
image quality control.
When the value increases by “1”, the
reproduction ratio of primary scan-
ning direction increases by approx.
0.07%. (approx. 0.1mm/step)
When the value increases by “1”, the
writing start position shifts to the front
side by approx. 0.0423mm.
When the value increases by “1”, the
image shifts toward the trailing edge
of the paper by 0.0423 mm (effective
for all pages of continuous printing).
