SP2 Mode Number Function and [Setting]
2969*LD – PWM Selection
1* Printer Output LD – PWM
Selection
Changes the LD power PWM control for printed
copies. A smaller value produces a lighter image.
Use this SP to adjust the image density for printing
from a personal computer or printing a received fax
message.
[1 ~ 5 / 1 / 1 step]
2* Fax Output LD – PWM
Selection
Changes the LD power PWM control for printed fax
messages. A smaller value produces a lighter
image
Use this SP to adjust the image density for printing
fax messages.
[1 ~ 5 / 1 / 1 step]
2971 Toner Full Sensor Count
DFU
2972* Grayscale Limit A new feature of this machine that controls the
halftone density level to prevent deterioration of the
OPC. The halftone density is detected by the ID
sensor, and the machine adjusts the intensity of the
LD beam according to the upper/lower limit setting.
1* Upper Limit Defines the upper limit for grayscale.
A larger value allows a wider range of halftones at
the pale end of the scale. If the image contains pale
areas with fuzzy borders surrounded by dark areas,
reduce this value to make the borders clearer.
[0 ~ 100 / 85 / 1 step]
2* Lower Limit Defines the lower limit for grayscale.
A smaller value allows a wider range of halftones at
the dark end of the scale.
[0 ~ 100 / 65 / 1 step]
2973* 1* Grayscale Copy Interval
Check
Sets the halftone operation interval in order to
prevent deterioration of the OPC. If the number of
copies exceeds this setting, at the end of the job, or
if the door is opened and closed, charge correction
is executed.
[0 ~ 1000 / 100 / 10 step]
2974* 1* Image Density Adjustment Adjusts image density. Changing this setting
adjusts development bias and ID sensor output
voltage that in turn raises or lowers image density.
[1 ~ 5 / 3 / 1 step]
2980* Charge Counter Sets the number of pages to print after toner and
carrier initialization before the charge input is
increased to compensate for deterioration over time
in the polarity of the carrier.
[0 ~ 1000000 / 0 / 1 step]
The strength in the polarity of the carrier in the
toner will eventually decrease and cause lower
charge output. Setting the charge output to
increase after a specified number of copies can
compensate for this effect.
