The machine warranty does not coverdamage caused by using a refilled cartridge.• Store print cartridges in the same environment as your machine.• To prevent damage to the print cartridge, do not expose it to light for morethan a few minutes.Expected Cartridge LifeThe life of the Smart Kit ® Print Cartridge depends on the amount of toner thatprint jobs require. When printing text at ISO 19752 5% coverage, a new printcartridge lasts an average of 3,000 pages. (The original print cartridgesupplied with the machine lasts an average of 1,000 pages.) The actualnumber may be different depending on the print density of the page you print.If you print a lot of graphics, you may need to change the cartridge more often.Redistributing Print Cartridge TonerWhen the print cartridge is near the end of its life, white streaks or light printingmay occur. The LCD displays the warning message, “Toner Low”. You cantemporarily recover print quality by redistributing the remaining toner in thecartridge.
