Item
DRUM_SEL Use it to set the sensitivity to
suit the photosensitive drum.
ATM Use it to set the operating envi-
ronment in relation to the
atmospheric pressure. (A high-
er setting will lower the target
potential of potential control. A
low pressure tends to cause
leakage, requiring lowering the
target potential for potential
control.)
BRAKE_SC Use it to adjust the braking for when
the scanner is moving in reverse.
LE_BLANK Use it to adjust the margin
along the leading edge width.
(ON period of blank exposure lamp)
MULT_SZ Use it to correct the input data
of the multifeeder paper width
detecting variable resistor.
