5.4 < Loading print media>Transparencies • To avoid damaging the printer, use onlytransparencies designed for use in laserprinters.• Transparencies used in the printer must be ableto withstand the machine’s fusing temperature.Check your machine’s specification to view thefusing temperature, see page 11.1.• Place them on a flat surface after removingthem from the printer.• Do not leave them in the paper tray for longperiods of time. Dust and dirt may accumulateon them, resulting in spotty printing.• To avoid smudging caused by fingerprints,handle them carefully.• To avoid fading, do not expose printedtransparencies to prolonged sunlight.• Ensure that transparencies are not wrinkled,curled, or have any torn edges.Labels • To avoid damaging the printer, use only labelsdesigned for use in laser printers.• When selecting labels, consider the followingfactors:- Adhesives: The adhesive material should bestable at 180° C (356° F), the printer’s fusingtemperature.- Arrangement: Only use labels with noexposed backing between them. Labels canpeel off sheets that have spaces between thelabels, causing serious jams.- Curl: Prior to printing, labels must lie flat withno more than 13 mm (5 inches) of curl in anydirection.- Condition: Do not use labels with wrinkles,bubbles, or other indications of separation.• Make sure that there is no exposed adhesivematerial between labels. Exposed areas cancause labels to peel off during printing, whichcan cause paper jams. Exposed adhesive canalso cause damage to printer components.• Do not run a sheet of labels through the printermore than once. The adhesive backing isdesigned for only a single pass through theprinter.• Do not use labels that are separating from thebacking sheet or are wrinkled, bubbled, orotherwise damaged.Card stock orcustom-sizedmaterials• Do not print on print media smaller than 76 mm(3 inches) wide or 127 mm (5 inches) long.• In the software application, set margins at least6.4 mm (0.25 inches) away from the edges ofthe material.Type GuidelinesLoading paperLoad the print media you use for the majority of your print jobs in the tray1. 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 thestandard tray to load an additional 250 sheets of paper. For orderinformation for an optional tray, see 7.1.The paper level indicator on the front of the tray 1 and the optional tray2 shows the amount of paper currently left in the tray. When the tray isempty, the indicator bar is completely lowered.Preprintedpaper• Letterhead must be printed with heat-resistantink that will not melt, vaporize, or releasehazardous emissions when subjected to theprinter’s fusing temperature for 0.1 second.Check your machine’s specification to view thefusing temperature, see page 11.1.• Letterhead ink must be non-flammable andshould not adversely affect printer rollers.• Forms and letterhead should be sealed in amoisture-proof wrapping to prevent changesduring storage.• Before you load preprinted paper, such asforms and letterhead, verify that the ink on thepaper is dry. During the fusing process, wet inkcan come off preprinted paper, reducing printquality.Type Guidelines3250-033Full ▲ ▲ Empty
