Replacing the Toner Cartridge
When the toner eventually runs out, only blank pages print when a
print job is sent. At this stage, the toner cartridge needs to be
replaced. The machine stops printing.
1 Open the front cover.
2
Lightly pushing the used cartridge down, pull it 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.
