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 dr amatically 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 (n ot standing on end) with the same side facing up as if they were installed in the machine.
• Do not store
  consumable in;
- Temp
erature greater than 40°C (104°F).
-Humidit y range less than 20% nor greater than 80%.
- An envir
 onment with extreme changes in humidity or temperature.
- Direct sunlight or
  room light.
- Dusty places.
- A ca
r for a long period of time.
-An envir
 onment where corrosive gases are present.
- An envir onment with salty air.
Handling instructions
•Do not touch the surface of the photosensitive drum in the cartridge.
• Do not expose the cartr idge to unnecessary vibrat ions or shock.
• Never 
manually rotate the drum, especially in the reverse di rection; 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 mach ine 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.

Redistributing toner
When the toner cartridge is near the end of its life:
•White streaks or light printing occurs. 
•Pr
epare new cartridge  appears on the display.
• The Status  LED blinks red. 
If this happens, you can temporarily improve print quality by redistributing the r

cases, white streaks or light printing will stil l occur even after you have redistributed the toner.
1. Ope
n the front door.
2.Pull the toner  cartridge out.
3.Thoroughly roll the cartridge five or six times  to distribute the toner evenly inside the cartridge.
 If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into 
fabric.
 Do not touch the green underside of the toner cartridge. Use the handle on the cartridge to avoid touching this 
area. 
4. Hold the toner
  cartridge by the handle and slowly insert the cartridge into the opening in the machine.
