Maintaining the toner cartridge

Toner cartridge storage

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.
• Correct side up in a horizontal position (not standing on end).
• Do not store consumables in;
- Temperature greater than 40C (104F).
- 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.
Note
Samsungs printer warranty does not cover damage to the
machine caused by the use of a refilled, remanufactured, or
non-Samsung brand toner cartridge.

Expected 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.
Redistributing toner
When the toner cartridge is near the end of its life.
• White streaks or light printing occurs.
• The message saying that the estimated toner cartridge life is closed
may appear on the display.
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.
1Turn the machine off, then wait a few minutes for the machine to
