5.3 <Loading print media>Guidelines for selecting and storing print mediaWhen selecting or loading paper, envelopes, or other print materials, keep these guidelines in mind:• Always use print media that conform with the specifications listed on page 5.3.• Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams and poor print quality.• For the best print quality, use only high quality copier grade paper specifically recommended for use in laser printers.• Avoid using the following media types:- Paper with embossed lettering, perforations, or a texture that is too smooth or too rough- Erasable bond paper- Multi-paged paper- Synthetic paper and thermally reactive paper- Carbonless paper and Tracing paper. • Use of these types of paper could result in paper jams, chemical smells, and damage to your printer.• Store print media in its ream wrapper until you are ready to use it. Place cartons on pallets or shelves, not on the floor. Do not place heavy objects on top of the paper, whether it is packaged or unpackaged. Keep it away from moisture or other conditions that can cause it to wrinkle or curl.• Store unused print media at temperatures between 15o C and 30o C (59o F to 86o F). The relative humidity should be between 10% and 70%.• Store unused print media in a moisture-proof wrap, such as a plastic container or bag, to prevent dust and moisture from contaminating your paper.• Load special media types one sheet at a time through the multi-purpose tray to avoid paper jams.• To prevent print media, such as transparencies and label sheets, from sticking together, remove them as they print out.Guidelines for special print mediaMedia type GuidelinesEnvelopes• Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following factors:- Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lb) or jamming may occur.- Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inches) curl, and should not contain air.- Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.- Temperature: You should use envelopes that are compatible with the heat and pressure of the printer during operation.• Use only well-constructed envelopes with sharp and well creased folds.• Do not use stamped envelopes.• Do not use envelopes with clasps, snaps, windows, coated lining, self-adhesive seals, or other synthetic materials.• Do not use damaged or poorly made envelopes.• Be sure the seam at both ends of the envelope extends all the way to the corner of the envelope.• Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the printer’s fusing temperature of 200° C (392° F) for 0.1 second. The extra flaps and strips might cause wrinkling, creasing, or jams, and may even damage the fuser.• For the best print quality, position margins no closer than 15 mm (0.6 inches) from the edges of the envelope.• Avoid printing over the area where the envelope’s seams meet.AcceptableUnacceptable
5.4 <Loading print media>Transparencies• To avoid damaging the printer, use only transparencies designed for use in laser printers.• Transparencies used in the printer must be able to withstand 200° C (392° F), the printer’s fusing temperature.• Place them on a flat surface after removing them from the printer.• Do not leave them in the paper tray for long periods of time. Dust and dirt may accumulate on them, resulting in spotty printing.• To avoid smudging caused by fingerprints, handle them carefully.• To avoid fading, do not expose printed transparencies to prolonged sunlight.• Ensure that transparencies are not wrinkled, curled, or have any torn edges.Labels• To avoid damaging the printer, use only labels designed for use in laser printers.• When selecting labels, consider the following factors:- Adhesives: The adhesive material should be stable at 200° C (392° F), the printer’s fusing temperature.- Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams.- Curl: Prior to printing, labels must lie flat with no more than 13 mm (5 inches) of curl in any direction.- Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.• Make sure that there is no exposed adhesive material between labels. Exposed areas can cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can also cause damage to printer components.• Do not run a sheet of labels through the printer more than once. The adhesive backing is designed for only a single pass through the printer.• Do not use labels that are separating from the backing sheet or are wrinkled, bubbled, or otherwise damaged.Card stock or custom-sized materials• Do not print on media smaller than 76 mm (3 inches) wide or 127 mm (5 inches) long.• In the software application, set margins at least 6.4 mm (0.25 inches) away from the edges of the material.Media type GuidelinesLoading paperLoad the print media you use for the majority of your print jobs in the tray 1. The tray 1 can hold a maximum of 250 sheets of 20 lb plain paper. You can purchase an optional tray (tray 2) and attach it below the standard tray to load an additional 250 sheets of paper. For order information for an optional tray, see page 7.1.The paper level indicator on the front of the tray 1 and the optional tray 2 shows the amount of paper currently left in the tray. When the tray is empty, the indicator of the bar is completely lowered.Preprinted paper• Letterhead must be printed with heat-resistant ink that will not melt, vaporize, or release hazardous emissions when subjected to the printer’s fusing temperature of 205° C (400° F) for 0.1 second.• Letterhead ink must be non-flammable and should not adversely affect printer rollers.• Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during storage.• Before you load preprinted paper, such as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off preprinted paper, reducing print quality.Media type GuidelinesFull ▲ ▲ Empty

The printed side should be facing up with an uncurled edge at the front. If you experience problems with paper feed, turn the paper around. Note that the print quality is not guaranteed.Changing the size of the paper in the tray 1To load longer sizes of paper, such as Legal-sized paper, you need to adjust the paper guides to extend the paper tray.12341paper length guide2support guide3guide lock4paper width guides1Press and hold the guide lock, and slide the paper length guide to locate it in the correct paper size slot.2After inserting paper into the tray, adjust the support guide so that it lightly touches the paper stack.3Squeeze the paper width guides, as shown and slide them to the stack of paper until it lightly touches the side of the stack.
5.6 <Loading print media>Notes• Do not push the paper width guide far enough to cause the material to warp. • If you do not adjust the paper width guide, it may cause paper jams.Using the multi-purpose trayThe multi-purpose tray can hold special sizes and types of print material, such as transparencies, postcards, note cards, and envelopes. It is useful for single page printing on letterhead or colored paper. To load paper in the multi-purpose tray:1Open the multi-purpose tray and unfold the multi-purpose tray extension, as shown.2If you are using paper, flex or fan the edge of the paper stack to separate the pages before loading.For transparencies, hold them by the edges and avoid touching the print side. Oils from your fingers can cause print quality problems.3Load the paper with the side to be printed on facing up.Depending on the media type you are using, keep the following loading guidelines:• Envelopes: Flap side down and with the stamp area on the top left side.• Transparencies: Print side up and the top with the adhesive strip entering the printer first.• Labels: Print side up and top short edge entering the printer first.• Preprinted paper: Design side up with the top edge toward the printer.• Card stock: Print side up and the short edge entering the printer first.• Previously printed paper: Previously printed side down with an uncurled edge toward the printer.NoteMake sure that you have not loaded too much print material. The print material buckles if you load a stack that is too deep or if you push it in too far.CautionWhen you print on special material like envelopes, labels, transparencies, or cards, the output location should be the rear cover. Open the rear cover to use it. See page 5.8.4Squeeze the multi-purpose tray paper width guides and adjust them to the width of the paper. Do not force too much, or the paper will be bent, which will result in a paper jam or skew.
5.7 <Loading print media>5When you print a document, set the paper source and type in the software application. See the Software Section. For information about setting the paper source and type on the control panel, see page 2.3.6After printing, fold the multi-purpose tray extension and close the multi-purpose tray.Tips on using the multi-purpose tray• Load only one size of print media at a time in the multi-purpose tray.• To prevent paper jams, do not add paper when there is still paper in the multi-purpose tray. This also applies to other types of print media.• Print media should be loaded face up with the top edge going into the multi-purpose tray first and be placed in the center of the tray.• Always load only the print media specified in page 5.1 to avoid paper jams and print quality problems.• Flatten any curl on postcards, envelopes, and labels before loading them into the multi-purpose tray.• When you print on 76 mm x 127 mm (3 x 5 inches) sized media on the multi-purpose tray, open the rear cover for straight paper path to avoid paper jams.• Make sure to open the rear cover when you print on transparencies. If not, they may tear while exiting the printer.Using manual feed modeYou can manually load a sheet of print material in the multi-purpose tray if you select Manual Feed in the Source option from the Paper tab when you change print settings to print a document. See the Software Section. Manually loading paper can be helpful when you want to check the print quality after each page is printed. This loading procedure is almost the same as the procedure for loading in the multi-purpose tray, except you load paper sheet-by-sheet in the tray, send print data to print the first page, and press Stop (if you use the ML-3050) or OK (if you use the ML-3051N or ML-3051ND) on the control panel to print each following page.1Load the paper with the side to be printed on facing up. 2Squeeze the multi-purpose tray paper width guides and adjust them to the width of the paper. Do not force too much, or the paper will be bent, which will result in a paper jam or skew.3When you print a document, set the paper source to Manual Feed and select the appropriate paper size and type in the software application. See the Software Section. 4Print a document.The display shows a message prompting you to load paper and press Stop (if you use the ML-3050) or OK (if you use the ML-3051N or ML-3051ND).5Press Stop or OK. The printer picks up the print material and prints. After one page is printed, the message appears again.NoteIf you do not press the button, after a pause the printer will automatically pick the print material.6Insert the next sheet into the multi-purpose tray and press Stop or OK. Repeat this step for every page to be printed.
5.8 <Loading print media>Selecting an output locationThe printer has two output locations; the rear cover (face up) and the output tray (face down). The printer sends output to the output tray by default. To use the output tray, make sure that the rear cover is closed.Notes• If paper coming out of the output tray has problems, such as excessive curl, try printing to the rear cover.• To avoid paper jams, do not open or close the rear cover while the printer is printing.Printing to the output tray (Face down)The output tray collects paper face down, in the order in which the sheets were printed. The tray should be used for most print jobs. 11rear cover2output tray2Printing to the rear cover (Face up)Using the rear cover, paper comes out of the printer face up.Printing from the multi-purpose tray to the rear cover provides a straight paper path. Using the rear cover might improve the output quality with special print media.To use the rear cover, open it by pulling down.Unfold the duplex guide.CautionThe fuser area inside the rear cover of your printer becomes very hot when in use. Take care when you access this area.

This buildup can cause print quality problems, such as toner specks or smearing. Your printer has a cleaning mode that can correct and prevent these types of problems.Cleaning the outside of the printerClean 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.CautionCleaning 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 printerThere 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 manually1Turn the printer off and unplug the power cord. Wait for the printer to cool down.2Open 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.
8.2 <Maintenance>3With a dry lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and the toner cartridge cavity.CautionWhile 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.4Locate 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.5Reinsert the toner cartridge and close the front cover.6Plug in the power cord and turn the printer on.Printing a cleaning sheetIf 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.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 cartridgeToner cartridge storageTo 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 lifeThe 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 TonerTo 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.
