- As the value increases, the sen-
sor output increases correspond-
ingly.
- The value starts changing
approx. 2 minutes after this ad-
justment was started and is auto-
matically set in the range of 2.35
to 2.45V.
(
chapter 2.2)
Adjustment value of auto-toner
sensor can be displayed.
As the value increases by “1”, out-
put from the transformer increases
correspondingly. Remove the de-
veloper unit and install the service
jig to make adjustment. However,
the service jig is not necessary to
adjust the developer bias DC.
(
chapter 2.5)
When the value increases by “1”,
the laser output increases corre-
spondingly.
When the value increases by “1”,
the image shifts toward the leading
edge of paper by approx. 0.17mm.
When the value increases by “1”,
image shifts toward the rear side
of paper by approx. 0.0423mm.
Moves the carriages to the adjust-
ment position.
(
chapter 2.3.4)
When the value increases by “1”,
the reproduction ratio of the sec-
ondary scanning direction de-
creases by approx. 0.025%.
When the value increases by “1”,
the aligning amount increases by
approx. 0.5mm.
Perform the adjustment and initiali-
zation when the PC board or sen-
sor of the RADF is replaced.
When the value increases by “1”,
the reproduction ratio of the sec-
ondary scanning direction on origi-
nal fed from the RADF increases
by approx. 0.1%.
When the value increases by “1”,
the image of original fed from the
RADF shifts toward the rear side
of paper by approx. 0.0423mm.
