6.9.4 TONER END SENSORS
The toner end sensors are below the sub hoppers for each color
[A]: K (Black)
[B]: M (Magenta)
[C]: C (Cyan)
[D]: Y (Yellow)
The toner end sensor monitors the amount of toner in the sub hopper and issues
the near-end alert when toner runs low in the sub hopper.
Toner near-end
When a toner end sensor detects no toner in a sub hopper, the toner supply clutch
in that sub hopper engages and operates the toner pump for 2 seconds to supply
more toner from the toner cartridge (STC) to the sub hopper.
If the toner end sensor cannot detect toner in a sub hopper after 10 consecutive
readings, this triggers the toner near-end alert (this number of readings can be
adjusted with SP3411 007-008).
