WHEN TO REPLACE THE TONER CARTRIDGE
B4100, B4250
Replace the toner cartridge after Toner Low displays in the printer Status
Monitor. Also, the Error LED indicator slowly blinks when toner is low.
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.
B4350, B4350n
When the toner is running low, TONER LOW is displayed in the operator
panel LCD. If printing continues without replacing the toner cartridge,
CHANGE TONER is displayed and printing is cancelled. Printing will
resume after a new toner cartridge has been installed.
REPLACING 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
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.
