Toner Near End (TNE) / Toner End (TE) Detection
Toner near end detection: A counter determines when the toner has almost run out by calculating the remaining toner
from the initial amount of toner and subsequently replenished toner.
Toner end detection: A sensor checks whether toner is being added to the PCDU. If it cannot see that toner is being
replenished, then the machine detects that toner has actually run out, and the machine cannot print.
The toner near end counter works as follows:
The near-end alert sounds when the number of prints that can be made until toner end is as follows (Rough indication)
