2: TD Sensor Supply Mode
3: Fixed Supply Mode
Toner Supply Clutch ON Time:
S x AT x TSC ⁄ 100
ON Time (ms) =
TS
where S = Paper Size (cm
AT = Amount of the toner developed to the latent image for the specific
area = 0.7 (mg/cm
TSC = Toner supply coefficient (%)
TS = Amount of supplied toner for the specific time [constant]
= 0.183 (mg/ms) for A153, A155, A156 copiers
= 0.133 (mg/ms) for A157, A159, A160 copiers
