Cleaning the Drum Unit
We recommend placing the drum unit on a drop cloth or large disposable
paper to avoid spilling and scattering toner.
1 Clean the primary corona wire inside the drum unit by gently sliding the
blue tab from right to left several times.
2 Return the blue tab to the home position (▼) and snap it into place.

(See Replacing the Drum Unit on page 11-17.)
4 Close the front cover.
5 Plug in the power cord first, then the telephone cord.
Replacing the Toner Cartridge
The machine can print up to 6,000 pages using a high yeild toner
cartridge. When the toner cartridge is running low, the display shows
TONER LOW. The machine is supplied with a standard toner cartridge
that must be replaced after approximately 3,000 pages. Actual page count
will vary depending on your average document type (i.e., standard letter,
detailed graphics).
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. If you are
not sure of them, consult your local Sanitation Department. Be sure to
seal the toner cartridge tightly so toner powder does not spill out of the
cartridge. When discarding used toner cartridges, keep them separate
from domestic garbage.
We recommend that you clean the machine when you replace the toner
cartridge.
