Choosing Paper and Other Media Paper Guidelines When selecting or loading paper, envelopes, or other special media, keep these guidelines in your mind: • Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams and poor print quality. • Use cut-sheet paper only. You cannot use multi-part paper. • Use only high-quality, copier grade paper. • Do not use paper that has been already printed on or that has been fed through a photocopier.
Selecting the Output Location The printer has two output locations: the face-up output slot and the face-down output tray. You can select the output location by changing the position of the output lever on the front of the printer. To use the face-down output tray, be sure the output lever is in upper (normal) position. To use the face-up output slot, push it down to open the slot.
Loading Paper Proper paper loading helps prevent paper jams and ensure trouble-free printing. Do not remove paper from the tray(s) while a job is printing. Doing so may cause a paper jam. Using the Automatic Input Tray The automatic input tray holds 150 sheets of plain paper and 5 sheets of special media. See “Media Sizes and Capacities” on page 4.2 for acceptable paper size and capacities for each input trays. Load a stack of paper into the automatic input tray and print.
Loading Paper 2 Push the output lever down to open the face-up output slot. 3 When you print a document, you must select Manual for Paper Source from the software application, and then select the correct paper size and type. For details, see page 5.3. 4 Print the document. 5 If you are printing multiple pages, load next sheet after the first page prints out. 6 Press Demo to start feeding. Notes: • The face-up output slot may not hold the printed pages properly.
Printing on Envelopes Guidelines • Only use envelopes recommended for laser printers. Before you load envelopes in the input tray, make sure that they are undamaged and are not stuck together. • Do not feed stamped envelopes. • Never use envelopes with clasps, snaps, windows, coated lining, or self-stick adhesives. These envelopes may severely damage the printer. 1 Flex or fan the envelopes to supply air through them for loading.
Printing on Envelopes 4 Push the output lever down. 5 When you print on envelopes, configure the paper source, type and size properly in the software application. For details, see page 5.3. 6 Print the document. 7 After printing, push the output lever up. 4.
Printing on Heavy Paper Guidelines • Heavy paper is any paper heavier than 24 lb (90 g/m2). For cotton papers, you can use 24 lb paper. The maximum paper weight available for your printer is 43 lb (163g/m2). • Do not use extremely heavy paper stock (greater than 43 lb, or 163 g/m2 bond). Misfeeds, mis-stacking, media jams, poor toner fusing, poor print quality, and excessive mechanical wear can result. 1 Load paper in the input tray you want to use with print side up.
Printing on Labels Guidelines • Only use labels recommended for laser printers. • Verify that the labels’ adhesive material can tolerate fusing temperature of 200°C (392°F) for 0.1 second. • Make sure that there is no exposed adhesive material between the 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 feed a sheet of labels through the printer more than once.
Printing on Transparencies Guidelines • Only use transparencies recommended for use in laser printers. • Make sure that the transparencies are not wrinkled or curled, and that they do not have any torn edge. • Hold the transparencies by the edges and avoid touching the print side. Oils from your fingers that are deposited on the transparency can cause print quality problems. • Be careful not to scratch or leave fingerprints on the print side.
Printing on Preprinted Paper Preprinted paper is a form with some type of printing on them before they are sent through the printer, such as a letterhead having preprinted logo or text located at the top of the page. Guidelines • Letterheads 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 400°F (205°C) for 0.1 second.
Printing on Card Stocks Postcards, 3 by 5 in.(index) cards can be printed with the Samsung ML-4500 printer. Guidelines • Always insert the short-edge first into the input tray. If you want to print in landscape mode, make this selection through your software. Inserting paper long-edge first may cause a paper jam. • Do not print on the card stocks that is too small or too large. The minimum size is 76 by 127 mm (3 by 5 in.) for the manual input tray and 95 by 127 mm (3.8 by 5 in.

Make sure the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges. If you are unsure of what type of paper you are loading (such as bond or recycled), check the label on the package of the paper. The following problems with paper cause print quality deviations, jamming, or even damage to the printer.
Paper Specifications Paper Specifications Category Specifications Acid Content 5.5 ~ 8.0 pH Caliper .094 ~ .18 mm (3.0 ~ 7.0 mils) Curl in Ream Flat within 5 mm (.02 in.) Cut Edge Conditions Cut with sharp blades with no visible fray. Fusing Compatibility Must not scorch, melt, offset, or release hazardous emissions when heated to 200 °C (392 °F) for .1 second.
Paper Specifications Printer and Paper Storage Environment Ideally, the printer and paper storage environment should be at or near room temperature, and not too dry or humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly. Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room.
Paper Specifications Envelopes Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components: • Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lbs), otherwise, jamming may occur.
Paper Specifications Envelopes with Double Side Seams Double side-seams construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.
Paper Specifications Labels CAUTIONS: • To avoid damaging the printer, use only labels recommended for laser printers. • To prevent serious jams, always use the face-up output slot. • Never print on the same sheet of labels more than once or print on a partial sheet of labels. When selecting labels, consider the quality of each component: • Adhesives: The adhesive material should be stable at 200 °C (392 °F), the printer’s fusing temperature.
