2-301 * 1 * Transfer Current
Adjustment
(1st side of the
paper) Adjusts the current applied to the
transfer belt during copying on the 1st
side of the paper.
If the user uses thicker paper, the
current may have to be increased to
ensure sufficient transfer of toner.

Adjustment
(Leading edge of
the paper)
Increase the current to separate the
paper from the drum properly in high
humidity and high temperature
conditions.

2-309* 1* Adjusts the lower paper width threshold
for the transfer current correction. 0 ~ 297

150 mm Transfer Current
Correction a
(Paper width -
lower)
Use this SP when an image problem
(e.g., insufficient toner transfer) occurs
with a small width paper. If the paper
width is smaller than this value, the
transfer current will be multiplied by the
factor in SP2-309-3 (paper tray) or SP2-
309-5 (bypass).
Refer to Detailed Section Descriptions –
Image Transfer for more details.

216 mm Transfer Current
Correction b
(Paper width –
upper)
As for SP2-309-1, but the factors are in
SP2-309-4 (paper tray) and SP2-309-6
(bypass).
