5.13 ID SENSOR TONER SUPPLY LEVEL
The amount of toner supplied depends on the toner supply level data, toner
supply ratio data, and the paper size. The toner supply clutch on time (in pul-
ses) is calculated as follows:
MC ON Time = l x T x P
Where:
I = ID Sensor Supply level Data
T = Toner Supply Ratio Data
P = Paper Size Data
For example: Vsp = 0.65V which means that the ID sensor toner supply
level is “2” and the data = 52
The toner supply ratio is 15% which means that the
corresponding data = 2
Paper size is A4 so the paper size data = 1
The toner supply clutch turns on for 104 (52 x 2 x 1) pulses. One pulse is
2.259 milliseconds so the clutch on time is 235 milliseconds.
