Consumables and Maintenance
This section deals with the replacement of the toner cartridge and image drum and
general maintenance.
T
ONER CARTRIDGE LIFE
How long your toner cartridge lasts depends on the print density; the percentage of the
page that prints black. A typical letter has 3% to 5% print density; graphics usually
have higher density. Higher print density means toner is used up faster. At 5% print
density, a standard toner cartridge will print an average of 3500 pages. Remember, this
is only an average:actual results may vary.
The first toner cartridge installed in a new printer has to fill the image drum reservoir
and saturate the developing roller with toner. The toner cartridge that is supplied with
this printer normally produces about 1,500 pages after installation.
W
HEN TO REPLACE THE TONER CARTRIDGE
When the toner is running low, TONER LOW is displayed in the operator panel LCD. After
Toner Low displays, the printer will print about 100 more pages then display Toner
Empty and stop printing. Printing will resume after a new toner cartridge has been
installed.
R
EPLACING THE TONER CARTRIDGE
It is recommended that you clean the LED array at the same time as you change the
toner cartridge.
The toner used in this printer is a very fine dry powder contained in the toner cartridge.
Have a sheet of paper handy so that you have somewhere to place the used cartridge
while you install the new one.
Dispose of the old cartridge responsibly, inside the pack that the new one came in.
Follow any regulations, recommendations, etc., which may be in force concerning waste
recycling.
If you do spill any toner powder, lightly brush it off. If this is not enough, use a cool,
damp cloth to remove any residue. Do not use hot water, and never use solvents of any
kind. They will make stains permanent.
WARNING
• Never expose a toner cartridge to an open flame. It can cause
an explosion and you can be burned.
• Be sure to switch off and unplug the machine before
accessing the interior of the machine for cleaning,
maintenance or fault clearance. Access to a live machine’s
interior can cause electric shock.
WARNING!
If you inhale any toner or get it in your eyes, drink a little water
or bathe your eyes liberally in cold water. Seek medical attention
immediately.
