Replacing the Toner Bottle and Cleaner Pad
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 about 2500
pages under the same condition.
Replace the toner bottle and the cleaner pad at the same time when
the message display indicates
TONER LOW & PAD
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.
