[T bias Control] Transfer Bias Control
Use these SP's to adjust the power output and power coefficient used to
transfer the toner image from drum to paper. Four separate voltages are
applied before the leading edge, at the leading edge of the paper, across
2301 the image area and at the trailing edge of the paper.
Notes:

The coefficient adjustment should be done before the power output.

The amount of voltage applied to each area can be set independently
in each area for the type of paper in use.

[1 to 50 / 14 / 1uA/step]
E* Displays the setting of the transfer bias
control level for non image area.
[-15 to 15 / 0 / 1uA/step]
Displays the setting of the offset
E* amount of transfer bias control level
during creating an image on the face
page.
[-15 to 15 / 0 / 1uA/step]
Displays the setting of the offset
E* amount of transfer bias control level
during creating an image on the back
page.
[0 to 100 / 80 / 1%/step]
Output adjustment for the value of the
E* transfer output table which is to be a
basis when the transfer paper count is
in the range of 15K and 30K.
[0 to 100 / 70 / 1%/step]
Output adjustment for the value of the
E* transfer output table which is to be a
basis when the transfer paper count is
in the range of 30K and 60K.
