7.3 TONER SUPPLY CONTROL
7.3.1 Detect Supply Mode (SP #30 = 0)
The amount of toner supplied depends on the ID sensor data, the detect
toner supply ratio data, the paper size data, and color data. The toner supply
clutch on time in each copy cycle is calculated as explained below.
Toner Supply Clutch ON Time:
ON time (msec.)= 2.777 x 1/20 x [Toner Supply Ratio Parameter]
x [ID Sensor Level Parameter] x [Paper Size parameter]
x [Color Parameter]
Example:
•
SP mode #31 is set to "0".
Toner supply ratio parameter =2
•
Vsp=0.44V, Vsg= 4.0 V.
ID sensor level parameter=1/2
•
Paper size is A3 or DLT.
Paper size parameter=49
•
Copies are made by black toner mode.
Color parameter=24
ON time = 2.777 x 1/20 x 2 x 1/2 x 49 x 24
= 163 (msec.)
