Printing a machine report
Press and hold Stop/Clear button for about 4 seconds to print a machine report.
Cleaning your machine
To maintain print quality, follow the cleaning procedures below each time 
the toner cartridge is replaced or if print and scan quality problems occur.
Caution
• Cleaning the machine cabinet with cleaning materials that 
contain large amounts of alcohol, solvent, or other strong 
substances can discolor or damage the cabinet.
• If your machine or its surrounding is contaminated with toner, 
we recommend you to use cloth or tissue dampened with 
water to clean it. If you use a vacuum cleaner, toner blows in 
the air and might be harmful for you. 
• After cleaning, wipe the cabinet to remove any moisture.
Cleaning the outside
Make sure to brush off the dirt on the cloth provided before cleaning the 
cabinet. Make sure to spray water 4 to 6 times onto the cloth provided, or 
another cloth suitable for this purpose before cleaning the cabinet, wiping 
in on direction. 
Cleaning the inside
During the printing process, paper, toner and dust particles can 
accumulate inside the machine. This buildup can cause print quality 
problems, such as toner specks or smearing. Cleaning the inside of the 
machine clears or reduces these problems. Contact a service 
representative to clean the parts inside the machine.
1Press the top cover lever, completely open the top cover.   
2Grasp the handles on the toner cartridge and pull to remove the 
cartridge from the machine.    
Caution
• Do not touch the green surface, the OPC drum or the front of 
the toner cartridge, with your hands or any other material. 
Use the handle on each cartridge in order to avoid touching 
this area.
• If you leave the top cover open for more than a few minutes, 
the OPC drum can be exposed to light. This will cause 
damage to the OPC drum. Close the top cover should the 
installation need to be halted for any reason.

3With a dry lint-free cloth, wipe away any dust and spilled toner from 
the toner cartridges area and their cavities. 
Note
If toner gets on your clothing, wipe it off with a dry cloth and 
wash it in cold water. Hot water sets toner into fabric. 
4Locate the long strip of glass (LSU) inside the front door, and gently 
swab the glass to see if dirt turns the white cotton black.        
5Slide the toner cartridge back into the machine.
6Hold the top cover and close it slowly and carefully, until the cover is 
the cover is securely latched.   
Note
If the top cover is not completely closed, the machine will not 
operate.

Maintaining the 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 40°C (104°F). 
- Humidity range less than 20% and 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.
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. 
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.
Caution
• 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.

Redistributing toner
When small amount of toner is left in the cartridge, the toner 
LED( ) blinks slowly. It may cause faded or light areas on a paper. You 
can temporarily improve print quality by redistributing the toner. 
For detailed information about error message, see page  9.7. 
Note
In some cases, white streaks or light printing will still occur even 
after you have redistributed the toner. 
1Press the top cover lever, completely open the top cover.   
2Grasp the handles on the toner cartridge and pull to remove the 
cartridge from the machine.    
3Holding side edges of the toner cartridge, thoroughly rock it from 
side to side to redistribute the toner.
Caution
• Do not touch the green surface, the OPC drum or the front of 
the toner cartridge, with your hands or any other material. 
Use the handle on each cartridge in order to avoid touching 
this area.
• If you leave the top cover open for more than a few minutes, 
the OPC drum can be exposed to light. This will cause 
damage to the OPC drum. Close the top cover should the 
installation need to be halted for any reason.
