Caution • Cleaning the cabinet of the machine with cleaning materials containing large amounts of alcohol, solvent, or other strong substances can discolor or distort the cabinet. • If your machine or its around is contaminated with toner, we recommend you to use cloth or tissue dampened with water to clean it.

The machine warranty does not cover damage caused by using a refilled cartridge. • Store toner cartridges in the same environment as your machine. • To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Expected cartridge life The life of the toner cartridge depends on the amount of toner that print jobs require. The actual number may also be different depending on the print density of the pages you print on, and the number of pages may be affected by operating environment, printing interval, media type, and media size. If you print a lot of graphics, you may need to change the cartridge more often. Redistributing toner When the toner cartridge is near the end of its life: • White streaks or light printing occurs. • The toner related message telling that the toner is low. • SmartPanel program window appears on the computer telling you which color cartridge is low on toner. • The Status LED blinks red. If this happens, you can temporarily reestablish print quality by redistributing the remaining toner in the cartridge. In some cases, white streaks or light printing will still occur even after you have redistributed the toner. 1 Open the front cover. 2 Pull the corresponding toner cartridge out. 3 Holding the toner cartridge, thoroughly roll it 5 or 6 times to distribute the toner evenly inside the cartridge. 4 Grasp the toner cartridge and align it with the corresponding slot inside the machine. Insert it back into its slot until it clicks into place. 5 Close the front cover. Make sure that the cover is securely closed. Note If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric. 10.5 Replacing the toner cartridge The machine uses four colors and has a different toner cartridge for each one: yellow (Y), magenta (M), cyan (C), and black (K). When the toner cartridge is completely empty: • The Status LED and the toner-related message on the display indicate when each individual toner cartridge should be replaced. • The machine stops printing. At this stage, the toner cartridge needs to be replaced.
