Your printer has a cleaning mode that can correct and prevent these types of problems. Cleaning the outside of the printer Clean the cabinet of the printer with a soft, lint-free cloth. You can dampen the cloth slightly with water, but be careful not to let any water drip onto or into the printer. Caution Cleaning the cabinet of the printer with cleaning materials containing large amounts of alcohol, solvents, or other strong substances can discolor or crack the cabinet. Cleaning the inside of the printer There are two methods to clean the inside of the printer: • Clean the inside manually. • Print a cleaning sheet, which can be done from the control panel. Cleaning the Inside of the printer manually 1 Turn the printer off and unplug the power cord. Wait for the printer to cool down. 2 Open the front cover and pull the toner cartridge out. Set it on a clean flat surface. Cautions • 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. • Do not touch the green surface underside of the toner cartridge. Use the handle on the cartridge to avoid touching this area. 3 With a dry lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and the toner cartridge cavity. Caution While cleaning the inside of the printer, be careful not to touch the transfer roller, located underneath the toner cartridge. Oil from your fingers can cause print scan quality problems. 8.1 Locate the long strip of glass (LSU) inside the top of the cartridge compartment, and gently swab the glass to see if dirt turns the white cotton black. 5 Reinsert the toner cartridge and close the front cover. 6 Plug 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. In the ML-3050, press and hold down Stop for about 10 seconds to print a OPC cleaning sheet. In the ML-3051N and ML-3051ND, this process will produce a page with toner debris, which should be discarded. 1 Make sure that the printer is turned on with paper loaded in the tray. 2 Press Menu until System Setup appears on the bottom line of the display and press OK. 3 Press the Scroll buttons until Maintenance appears and press OK. 4 When 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 To get the most from the toner cartridge, keep the following guidelines in mind: • Do not remove the toner cartridge from its package until ready for use. • Do not refill the toner cartridge. The printer warranty does not cover damage caused by using a refilled cartridge. • Store toner cartridge in the same environment as the printer. • To prevent damage to the toner cartridge, do not expose it to light for more than a few minute. Expected cartridge life The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at ISO 19752 5% coverage, a new toner cartridge lasts an average of either 8,000 or 4,000 pages. (The original toner cartridge supplied with the printer lasts an average of 4,000 pages.) The actual number may also be different depending on the print density of the pages you print on, and the number of pages may be affected by operating environment, printing interval, media type, and media size. If you print a lot of graphics, you may need to change the cartridge more often. Saving Toner To save toner, press Toner Save on the control panel. The button backlight turns on. Using this feature extends the life of the toner cartridge and reduce your cost per page, but it also reduces print quality. Checking the remaining toner (ML-3051N, ML-3051ND only) You can check the level of toner left in the cartridge. If you are having print quality problems, this can help you determine if the problem is caused by low toner. 1 Press Menu until System Setup appears on the bottom line of the display press OK. 2 Press the Scroll buttons until Maintenance appears and press OK. 3 Press the Scroll buttons until Supplies Life appears and press OK. 4 Press the Scroll buttons to access Toner Remains and press OK.
