Toner Cartridge

Toner Supply

The toner supply clutch turns ON and a coil in the toner cartridge rotates to transfer toner to the bottle tap and then the PCDU. Toner which falls into the PCDU is transferred to the development section by the upper mixing coil.

New Unit Detection

The machine reads the ID chip to detect the status of the cartridge.

Toner Near End (TNE) / Toner End (TE) Detection

The TE sensor is mounted on the LED unit. It monitors toner supply through the TNE detection window

TNE is detected when the TE sensor on the LED unit detects non-supply of toner after the toner supply count by the software has exceeded the specified amount.

When TNE is detected, TNE information is written to the ID chip. TE information is written to the chip when the TE sensor detects TE.

The number of prints that can be made after toner near end (Rough indication)

Normal (Before 5 days): 475pages

Notify Later (Before 3 days): 285pages

Notify Sooner (Before 7 days): 665pages

*Users can set “Normal/ Notify Sooner/ Notify Later”. The default is “Normal”.

*The number of prints is a reference value for the following conditions: “A4, SEF, Color ratio 50%, Each color 5% on the original, Serial printing”. The actual amount (replacement cycle) fluctuates due to conditions such as: “paper size, paper type, page orientation, contents of original, P/J, and the number of times that process control and MUSIC are done”.
