As the value increases, the sensor output increases
correspondingly. The value starts changing approx. 2
minutes after this adjustment was started and is
automatically set in the range of 2.35 to 2.45 V.

When the high-voltage transformer is replaced, the
transfer cleaning bias needs to be adjusted with this
code. The larger the setting value is, the higher the
value of the current (more positive) is. This causes a
reduction in the toner adhering to the transfer roller and
an improvement in the cleaning performance. Perform
this adjustment after the process units (cleaner and
developer unit) have been removed. When the high-
voltage transformer is replaced, adjusting with the
following codes needs to be performed in addition to
this adjustment.
