SP2 Mode Number Function and [Setting]
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]
2975 1* Toner End Time Sets a time limit for issuing the toner near end
warning on the operation panel. The time may need
to be shorter for customers who run especially large
print jobs (working at night, for example) to ensure
earlier warning of the toner near end condition so
toner out does not interrupt a long job.
[0 ~ 2,000 /
0 / 10 s step]
0: Normal end detection (90 sheets after near-end
detected (SP2213)
2976 1* Toner Bottle On Count Displays the total ON time of the toner supply
motor, calculated from when the toner bottle was
replaced. Use this to check that the toner end count
(SP2975) is working properly.
[0 ~ 2,000,000 /
0 / 1 ms step]
When SP2975 is set to any value other than “0”,
this value is displayed when it matches the setting
of SP2975. When SP2975 is set to “0”, SP2976 is
disabled. SP2976 is automatically set to zero by
toner end recovery.
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.
2981 Polygon Mirror Revolution
Switching Switches the number revolutions per minute of the
polygon mirror motor.
