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.

the cleaner.)
SYS When the value increases by "1", the image shifts by
approx. 0.0846 mm toward the front side of the paper.
SYS When the value increases by "1", the image shifts by
approx. 0.13013 mm toward the trailing edge of the
paper.
SYS When the value increases by "1", the reproduction ratio
in the secondary scanning direction (vertical to paper
feeding direction) increases by approx. 0.025 %.
