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 <Remaining toner is low.> message appears, approximately 10% of the toner is left.
• If toner runs out during a print job, the remaining prints are made after you replace the toner cartridge.
