Storing the Toner cartridge
Toner cartridges contain components that are sensitive to light, temperature, and humidity. Samsung suggests users
follow the recommendations to ensure the optimum performance, highest quality, and longest life from your new Samsung
toner cartridge.
Store this cartridge in the same environment as the printer it will be used in; this should be in controlled office temperature
and humidity conditions. The toner cartridge should remain in its original, unopened package until installation – If original
packaging is not available, cover the top opening of the cartridge with paper and store in a dark cabinet.
Opening the cartridge package prior to use dramatically shortens its useful shelf and operating life. Do not store on the
floor. If the toner cartridge is removed 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 if they were installed in the machine.
• Do not store consumable in;
- Temperature greater than 40°C (104°F).
- Humidity range less than 20% nor 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; this can cause internal damage and toner spillage.
Use of non-Samsung and refilled toner cartridge
Samsung Electronics does not recommend or approve the use of non-Samsung 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 machine caused by the use of a refilled, remanufactured,
or non-Samsung brand toner cartridge.
Estimated cartridge life
Estimated cartridge life (the life of the toner cartridge yield) depends on the amount of toner that print jobs require. The
actual print-out number may vary depending on the print density of the pages you print on, operating environment, 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
you may need to change the cartridge more often.
