When you find the substance on the
drum surface that matches the print
sample, gently dab the surface of the
OPC drum with a cotton swab that is
lightly dampened with isopropyl alcohol.
CAUTION
The OPC drum is photosensitive so do not
touch it with your fingers.
Do not use a scrubbing or wiping motion
because this might damage the drum.
DO NOT clean the surface of the OPC
drum with a sharp object, such as a ball-
point pen, because this might cause
permanent damage to the drum unit.
Replacing the toner cartridge
(TN-550/TN-580)
C
The TN-580 toner cartridge can print
approximately 7,000 pages using a high yield
toner cartridge. When the toner cartridge is
running low, the LCD shows
Toner Low
.
The machine is supplied with a standard
TN-550 toner cartridge that must be replaced
after approximately 3,500 pages. 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 up the toner
cartridge tightly so that 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 machine
and corona wire of the drum unit when you
replace the toner cartridge. (See
