Tnr Supply Rate Toner Supply Rate: Display
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 between sheets (mm)/Drum speed (mm/s) x 1000.
Note: The toner supply control method is selected with SP3301.

Tnr SupplyLimits Set Upper/Lower Limits for Toner Supply
Sets the upper and lower limits for toner supply supply rate with the fuzzy logic (PID)
used as the toner supply control method. This SP takes effect only if 1 or 2 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.

These SPs set the toner supply coefficients for the fuzzy logic method of toner
supply control.
Note: These SP codes operate only when 1 or 2 is selected for SP3301.
