for more than a few minutes. Cover it with a piece of paper, if
necessary.

tridge. Oil from your fingers can cause print quality problems.

STORING THE TONER CARTRIDGE
Toner cartridges contain components that are sensitive to light, temperature
and humidity. Samsung suggests users follow the recommendations below
to ensure the optimum performance, highest quality and longest life from
your new Samsung toner cartridges.
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 instal-
lation – 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 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; this
can cause internal damage and toner spillage.
