4Locate the long strip of glass (LSU) inside the top of the cartridge compartment, and gently swab the glass with a cotton swab checking to see if dirt turns the cotton black.
5Reinsert the toner cartridge and close the front cover.
6Plug in the power cord and turn the printer on.
Printing a cleaning sheet
If you are experiencing blurred, faded, or smeared printouts, you can clear the problem by printing a cleaning sheet, provided by your printer. You can print:
•OPC Cleaning sheet: cleans the OPC drum of the toner cartridge.
•Fuser Cleaning sheet: cleans the fuser unit inside the printer.
This process will produce a page with toner debris, which should be discarded.
1Make sure that the printer is turned on with paper loaded in the tray.
2Press Menu until System Setup appears on the bottom line of the display and press OK.
3Press the scroll buttons until Maintenance appears and press OK.
4When Clean Drum appears, press OK.
Or, press the scroll buttons until Clean Drum or Clean Fuser appears and press OK.
Your printer automatically picks up a sheet of paper from the tray and prints out a cleaning sheet with dust or toner particles on it.
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 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.
