Replacing the Toner Cartridge

IMPORTANT
•
Use only the toner cartridges intended for use with this machine.
•
Do not replace toner cartridges until the message prompting you to do so appears.
•
The colour of the toner to be replaced is shown on the touch panel display. A toner cartridge revolver is
mounted inside the machine. It holds four toner cartridges and rotates. When toner of a particular colour
runs out, its toner cartridge is rotated to the toner supply port, and can be replaced. Only one toner
cartridge can be replaced at a time. However, when two or more toner cartridges have to be replaced at
the same time, replace them in this order: black, yellow, magenta, and cyan.
•
If you continue copying or printing in black-and-white after cyan, magenta, or yellow toner runs out, do
not remove the depleted toner cartridges from the machine.
•
Do not touch the shutter door and gear of the toner cartridge, as this may cause the toner cartridge to
leak.
NOTE
•
When the <Black toner is low. Replacement not yet needed.> message appears, approximately 10% of
the toner is left. It is recommended that you get a new toner cartridge ready for replacement before the
toner runs out.
•
If toner runs out during a print job, the remaining prints are made after you replace the toner cartridge.
