Thetoner cartridge should remain in its original, unopened package until instal-lation – If original packaging is not available, cover the top opening of thecartridge with paper and store in a dark cabinet.Opening the cartridge package prior to use dramatically shortens its usefulshelf and operating life. Do not store on the floor. If the toner cartridge isremoved from the printer, always store the cartridge:• Inside the protective bag from the original package.• Store lying flat (not standing on end) with the same side facing up as ifthey were installed in the machine.• Do not store consumables in;- Temperature greater than 40°C (104°F).- Humidity range not less than 20% nor not greater than 80%.- An environment with extreme changes in humidity or temperature.- Direct sunlight or room light.- Dusty places.- A car for a long period of time.- An environment where corrosive gases are present.- An environment with salty air.Handling instructions• Do not touch the surface of the photosensitive drum in the cartridge.• Do not expose the cartridge to unnecessary vibrations or shock.• Never manually rotate the drum, especially in the reverse direction; thiscan cause internal damage and toner spillage.Use of non-Samsung and refilled toner cartridgeSamsung Electronics does not recommend or approve the use of non-Sam-sung brand toner cartridges in your printer including generic, store brand,refilled, or remanufactured toner cartridges.Samsung’s printer warranty does not cover damage to the machinecaused by the use of a refilled, remanufactured, or non-Samsungbrand toner cartridge.Estimated cartridge lifeEstimated cartridge life (the life of the toner cartridge yield) depends on theamount of toner that print jobs require. The actual print-out number mayvary depending on the print density of the pages you print on, operatingenvironment, printing interval, media type, and/or media size. For example,if you print a lot of graphics, the consumption of the toner is high and youmay need to change the cartridge more often.TIPS FOR MOVING & STORING YOUR MACHINE• When moving the machine, do not tilt or turn it upside down.
