When to replace the toner cartridge
B4400
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.
B4500, B4550, B4600
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.
