Cleaning the corona wire
We recommend placing the drum unit and
toner cartridge assembly on a cloth or large
disposable paper to avoid spilling and
scattering toner.
1
Open the front cover and pull out the
drum unit and toner cartridge assembly.
2
Clean the primary corona wire inside the
drum unit by gently sliding the blue tab
from right to left several times.
3
Return the blue tab and snap it into the
Home position (
▼).
4
Reinstall the drum unit and toner
cartridge assembly in the DCP.
5
Close the front cover.
Replacing the toner cartridge
(TN-350)
The toner cartridge can print up to 2,500
pages. When the toner cartridge is running
low, the LCD shows
Toner Low
. Actual page
count will vary depending on your average
type of document (i.e., standard letter,
detailed graphics).
Note
It is a good idea to keep a new toner cartridge
ready for use when you see the
Toner Low
warning.
Discard the used toner cartridge according to
local regulations, keeping it separate from
domestic waste. Be sure to seal the toner
cartridge tightly so toner powder does not
spill out of the cartridge. If you have
questions, call your local waste disposal
office.
We recommend that you clean the DCP and
drum unit when you replace the toner
cartridge. (See Cleaning the laser scanner
window on page 6-17 and Cleaning the
corona wire on page 6-19.)
CAUTION
If you do not return the blue tab to the
Home position (
▼), your printed pages
may have vertical black stripes on them.
