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 nonSamsung 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 machine caused by the use of a refilled, remanufactured, or nonSamsung 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 Small amount of toner is left in the cartridge. You can temporarily improve print quality by redistributing the toner. 1. Open the front cover. For ML-2240 Series, if you have installed the dust cover, remove the dust cover before opening the front cover. 2. Pull the toner cartridge out and remove it from the machine. • Avoid reaching too far into the machine. The fusing area may be hot. • To prevent damage to the toner cartridge, do not expose it to light for more than few minutes. • Do not touch the green surface (or sky blue), the OPC drum, with your hands or any other material. Use the handle on the cartidge to avoid touching this area. • Be careful not to expose the green surface (or sky blue), the OPC drum, into light. This will cause damage to the OPC drum. Cover the toner cartridge's OPC drum with paper to avoid damaging it from the light. • Do not turn the toner cartridge over. Because the machine is very light, it may be moved when you use it; for example, when opening/closing the tray or installing/removing the toner cartridge. Be careful not to move the machine.
