Item Setting Objective When/How
Secondary trans-
fer voltage Range: -10 to +10
Increased values:
Higher secondary
transfer bias De-
creased values:
Lower secondary
transfer bias When image blurring oc-
curs, adjust the voltage
that transfers toner to the
paper. This setting can af-
fect the ‘Image clear level
adjustment’ and ‘Tail end
white patch correction’ set-
tings. If necessary, readjust
these settings too. De-
crease the value when: 1)
thin paper is used, 2) tiny
white spots appear in low-
density areas (when densi-
ty in high-density areas is
normal), 3) white spots ap-
pear in high-density areas
and 4) the used paper has
a rough surface (such as
embossed paper) and
white spots appear on the
concave side. Increase the
value when: 1) thick paper
is used, 2) the density level
in high-density areas and
low-density areas is low, 3)
uneven glossy areas occur
in high-density images and
4) outlines in high-density
images blur. Change this
setting in small steps and
check the output after each
adjustment.
