3303 Tnr Supply Rate
Displays for confirmation the toner supply rate of toner supply control using the PID method.
The toner supply rate is calculated as:
Toner Supply Rate = Toner Supply Time/Time Allowed for Toner Supply x 100
where:
• Time is measured in msec.
• "Time Allowed for Toner Supply (ms)" = Length of the paper (mm) + Width of the gap
Note: The toner supply control method is selected with SP3301.

3304 Tnr SupplyLimits
Set Upper/Lower Limits for Toner Supply.
Sets the upper and lower limits for toner supply rate with the fuzzy logic (PID) used as the
toner supply control method.
Note: This SP takes effect only if 1 is selected for SP3301 to enable fuzzy logic as the toner
supply method.
The machine reads 1) the maximum and minimum settings of this SP and 2) the toner
consumption of the output image surface (pixel count data). Then it calculates the maximum
and minimum amount of toner for that image. After this is done, toner supply amount will not
change during the job, even if Vt or any other measurement determines that more toner is
necessary.
