Toner Supply
The toner supply clutch turns ON and the coils in the toner cartridge rotate to transfer toner to the box tap and then the PCDU. The toner transferred to the PCDU is transferred to the development unit by the 1st mixing coil.
New Unit Detection
The machine reads the ID chip to detect the status of the cartridge.
ID chip information
The toner cartridge has an ID chip [1] that records how many sheets the copier has printed with its toner cartridge, and product information.
ID chip information can be checked when in SP mode.

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)
Notify Sooner | Before 7 days | about 920 pages |
Normal (factory default) | Before 5 days | about 660 pages |
Notify Later | Before 3 days | about 400 pages |
- This setting is not available in the UP mode. To adjust, use SP3-098-001 (Days Before End Toner) 0: Notify Sooner, 1: Normal, 2: Notify Later
- The number of prints (rough indication) that can be made after toner near end notification is calculated assuming an average print volume (APV) of 3,000 sheets per month.
- The number of prints is that when continuously printing the test chart on A4 paper at 6% coverage.
Used toner
The waste toner collection coil sends used toner in the PCDU down to the used toner box.
The used toner collection box does not have a function to detect when it is full.
