surface of the PC drum onto the paper.
(The transfer roller is not incorporated
in the imaging cartridge.)

unit consists of the LED and the sensor.
Light emitted from the LED is reflected
by the reflection mirror built in the
imaging cartridge and then detected by
the sensor. the sensor monitors the
toner's empty/near empty condition by
referring to the voltage level, pulse
width, and detected times of the
detection signal.
