Comments
After the selected
mode is set and
the main switch
turns off/on, the
fusing temperature
control is changed.
See SP31/SP32 for
ratios.
-260V = normal
-220V = lighter
-280V = darker
-300V = darkest
1: Shifts bias
output (+40V)
2: Shifts exposure
lamp voltage
(+2V)
This prevents low
image density
before toner end
detection.
When using mar-
gin adjustment
mode.
