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).
