Replacing the Toner Bottle
The toner bottle is designed to last approximately 5000 printed pages
under the condition of 5% coverage on A4 paper or last about one year
after unpacking. The first toner bottle may print slightly fewer pages.
Replace the toner bottle when the message display indicates
TONER LOW
or
TONER EMPTY
or when printing becomes lighter than you find
satisfactory. After the toner low condition occurs, you can only
print
about 20 more pages. Under the toner empty condition (no toner),
the printer will not work.
