Replacing the Toner Cartridge
When the toner eventually runs out, only blank pages print
when a print job is sent or when a fax is received. At this stage,
the toner cartridge needs to be replaced. The display on the
control panel shows the warning message, “[Toner Empty]” and
the machine stops printing.
N OTE : You can set the machine to ignore the “[Toner Empty]”
message and continue printing. See page 8.10.
1 Open the front cover.
2 Lightly pushing the used cartridge down, pull the cartridge
out.
3 Unpack the new toner cartridge and gently roll it
horizontally four or five times to distribute the toner evenly
inside the cartridge.
Save the box and the plastic bag for shipping.
4 Slide the new toner cartridge in until it locks into place.
5 Close the front cover.
