Toner Near End (TNE), Toner End (TE)
The TE sensors are mounted on the LED arrays.
They monitor toner supply through the TNE detection
windows in the PCDUs.
TNE is detected when the TE sensor detects non-supply of
toner. Then the near-end status is written to the ID chip.
Then, the toner end alert is shown after a certain number of
prints is made (the following are reference values based on
3 prints/job, color ratio 50%, 5% coverage for each color).
Normal (Before 5 days): 625 pages
Notify Later (Before 3 days): 375 pages
Notify Sooner (Before 7 days): 875 pages
Users can set
“Normal / Notify Sooner / Notify Later”.
The
default is “Normal”.
Then, the toner end status is written to the ID chip.
Approximate number of prints that can be made with each setting:
0: 875 pages before the end
1 (default): 625 pages before the end
2: 375 pages before the end
The number of prints is a reference value based on the following conditions:
A4, LEF, 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, number of
pages per job in serial printing, and the number of times that process control
and MUSIC are done. The numbers are based on drum rotation.
For example, if there are fewer prints per job, the toner will need to be
replaced earlier.
