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.

Maintaining the cartridge Redistributing toner 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. 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. 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. When a toner is low 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 7.7. Note In some cases, white streaks or light printing will still occur even after you have redistributed the toner. 1 Press the top cover lever, completely open the top cover. 2 Grasp the handles on the toner cartridge and pull to remove the cartridge from the machine. 6.3 3 Holding side edges of the toner cartridge, thoroughly rock it from 5 Hold the top cover and close it slowly and carefully, until the cover is side to side to redistribute the toner. t...
