SERVICE PROGRAM MODE TABLES
2976* Toner Bottle Total On Time
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.
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.
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 Rotation Switch DFU
Switches the number revolutions per minute of the polygon mirror motor.
0: Rpm determined by engine
1: Rpm for 35 CPM
