SP2 Mode Number Function and [Setting]
2975 01 Toner End Time Sets a time limit for issuing the toner near end
warning on the operation panel. The time may
need to be shortened for customers who run
especially large print jobs to ensure earlier
warning of the toner near end condition.
[0 ~ 2,000 / 0 / 10 s step]
0: Normal end detection (90 sheets after near-
end detected – SP2213)
Setting for 1300 s allows about 26 K prints at 5%
coverage starting with a new cartridge, before
the toner near-end warning is issued.
2976 01 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 when using 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 set for SP2975. When SP2975 is set to
“0”, SP2976 is disabled. SP2976 is automatically
set to zero by toner end recovery.
2980* 01 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.
[1 ~ 1,000K / 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 prints can
compensate for this effect.
