9.7.4 Checking the Level of Toner
The machine checks the level of toner using the following sensors:
T-9-32
F-9-38
Developing
assembly
ATR sensor
magnetic sensor
Description
checks the concentration of toner inside the developing assembly.
relies on the fact that a change in the ratio between carrier (magnetic) and toner (non-
magnetic) changes the force of magnetism.
detects changes to identify the level of toner.
SALT Sensor
photo sensor
Description
checks the sample toner formed on the intermediate transfer belt (ITB) at such times
as programmed.
checks the density of the toner image after development.
