Toner
When to replace toner cartridge
Replace the toner cartridge after TONER LOW dis-
plays in the control panel LCD. After TONER LOW
displays, the printer prints about 100 more pages, then
displays TONER EMPTY and stops printing. Printing
resumes after a new toner cartridge has been installed.
CAUTION:
The use of original toner or toner cartridges is highly
recommended. Using compatible or counterfeit toner or
toner cartridges can seriously damage the printer.
Toner cartridge life
How long your toner cartridge lasts depends on the
print density; the percentage of the page that prints
black. A typical letter has 3% to 5% print density;
graphics usually have higher density. Higher print den-
sity means toner is used up faster. At 5% print density,
a toner cartridge will print an average of 4000 pages.
Remember, this is only an average: actual results may
vary.
The first toner cartridge installed in a new printer has to
fill the image drum reservoir and saturate the develop-
ing roller with toner. This filling of the image drum res-
ervoir reduces the number of pages produced from the
first toner cartridge.

tridge.
2. Shake the new toner cartridge to evenly distribute
toner.
3. Unwrap the new toner cartridge and carefully
peel off the sealing tape.
