Transfer cleaning bias
adjustment (negative)
ALL 41
<0-255>
M 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 negative) 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 need to
be performed in addition
to this adjustment.
