Toner Near-end and Toner End Detection
This machine detects toner near-end and toner
end as follows:
Toner Near-end
A toner-end sensor, mounted on the left frame of the
machine, checks for a low-toner condition.
If the toner end sensor is activated ten times in a
row, the toner near-end condition exists.
Toner End
When the toner near-end condition occurs, the
machine starts the toner-end count.
Toner End is based on dot count. After toner
consumption equivalent to 1,250 A4 prints/copies at
5% coverage, the toner end condition is achieved.
(See the detection mechanism on the next two slides.)
