Laser Safety Statement IV Environmental and Safety Consideration Ozone Safety Power Saver During normal operation, the Samsung ML-1250 Series printer produces ozone. The ozone produced does not present a hazard to the operator. However, it is advisable that the machine be operated in a well ventilated area. If you need additional information about ozone, please request your nearest Samsung dealer. This printer contains advanced energy conservation technology that reduces power consumption when it is not in active use. When the printer does not receive data for an extended period of time,…

Setting Up Client PC Printing on a Network Environment 5.23 chapter This chapter provides suggestions for high-quality and economical printing and information for maintaining the toner cartridge and the printer. Topics included in this chapter are: Maintaining Toner Cartridge Cleaning the Printer 6 6 MAINTAININGYOURPRINTER 6.1 Maintaining Toner Cartridge To get the most from the toner cartridge, keep the following guidelines in your mind. • Do not remove the toner cartridge from its package until you are ready to use it. • Do not refill toner cartridges.The printer warranty does not cover damage caused by using a refilled cartridge. • Store toner cartridges in the same environment as the printer. • Do not remove a toner cartridge from the printer except to replace it, clean it or clear a paper jam. Replace the cartridge immediately. • To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Toner cartridge storage The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at 5 % coverage, a new toner cartridge lasts an average of 2,500 pages. (But, the toner cartridge supplied with the printer lasts an average of 1,000 pages.) Toner cartridge life expectancy After you install a new toner cartridge (see page 2.2), follow the instructions included in the toner cartridge box to recycle the old cartridge. Recycling toner cartridge To save toner, press the Toner Savebutton on the printer control panel. The button will be lit. You can also enable the Toner Save Modein your printer properties. Refer to “Using Toner Save Mode” on page 5.6. Selecting this option will extend the life of the toner cartridge and reduce your cost per page, but will reduce print quality. Saving toner MAINTAININGYOURPRINTER 6.2 Maintaining Toner Cartridge When toner is low, faded or light areas may appear on a printed page. You may be able to temporarily improve print quality by redistributing the toner. The following procedures may allow you to finish the current print job before replacing the toner cartridge. Redistributing Toner 1Grasp the front cover by both sides of the cover and pull it toward you to open. 2Remove the toner cartridge from the printer. CAUTIONS: • Avoid reaching too far into the printer. The fusing area may be hot. • To prevent damage to the toner cartridge, do not expose it to light formore than a few minutes. MAINTAININGYOURPRINTER 6.3 Maintaining Toner Cartridge 3Gently shake the toner cartridge from side to side 5 or 6 times to redistribute the toner. 4Reinsert the toner cartridge into the printer. Be sure that the toner cartridge snaps in its place. 5Firmly close the cover. If the print remains light Remove the old cartridge and install a new toner cartridge. See “Install the Toner Cartridge” on page 2.2. Note:If the toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric. MAINTAININGYOURPRINTER 6.4 Cleaning the Printer To maintain print quality, follow the cleaning procedures below every time the toner cartridge is replaced or whenever print quality problems occur. As much as possible, keep the printer free from dust and debris. Notes: • Do not use ammonia-based cleaners or volatile solvents such as thinner, on or around the printer. These can damage the printer. • While cleaning the inside of the printer, be careful not to touch the transfer roller (located underneath the toner cartridge ). The oil from your hands on the roller can cause print quality problems. Wipe the outside surface of the printer with a soft, clean, lint- free cloth. You can dampen the cloth slightly with water, but be careful not to let any water drip onto the printer or inside it. Cleaning the Outside During the printing process, paper, toner, and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems such as toner specks or smearing. Cleaning inside the printer will eliminate or reduce these problems. Cleaning the Inside 1 Turn the printer off and unplug the power cord, then wait for the printer to cool. 2 Open the front cover and remove the toner cartridge. 3 With a dry, lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and the toner cartridge cavity. Cleaning inside the printer Note:To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover it with a piece of paper, if necessary. Also, do not touch the black transfer roller inside the printer. By doing so, you can damage the printer. 3 Your printer automatically picks up a sheet of paper from the tray and prints out a cleaning sheet with the dust or toner particles on it. MAINTAININGYOURPRINTER 5 Then, plug in the power cord, and turn the printer on. Note:The cartridge cleaning process takes some time. To stop the printing, turn the power off. Cleaning the Printer Printing a cleaning sheet Printing a cleaning sheet cleans the drum inside the toner cartridge. Use this process if you are experiencing blurred, faded or smeared printouts. This process will produce a page with toner debris, which should be discarded. 1 Make sure the printer is turned on and in the Ready mode and that there is paper loaded in the automatic input tray. 2 Press and hold down Demoon the control panel for about 10 seconds until all control panel lights remain lit, then release the button. 4 Reinsert the toner cartridge and close the cover. 6.5 chapter This chapter gives helpful…
