Choosing Paper Labels - Use only labels designed for laser printers or plain-paper copiers in your printer. When printing labels, use the optional face-up output tray; this keeps the labels from curling or coming off the backing sheet. Always manually feed labels. To prevent the adhesive from coming into contact with the printer parts, always use labels that completely cover the backing sheet so that there are no gaps between the individual labels. You should test the label sheet for leaking adhesive by pressing a sheet of paper on top of a sheet of labels. If the paper sticks at all, do not use the labels. Other materials - You can use overhead projector transparencies and adhesive drafting film if they are made for use with plain-paper copiers or laser printers. When printing these materials, use the optional face-up output tray. Envelopes-You can insert several envelopes in the manual-feed slot for automatic loading. Load envelopes with the flap-side down as shown below. The printing quality on envelopes may be irregular because different parts of an envelope have different thicknesses, and the thickness or weight of particular envelopes may affect your results. Test a sample envelope before you buy a large number. Also, use the optional face-up output tray to keep the envelopes from curling. If the printing is too light, turn the print density knob counterclockwise. Always return the print density knob to the center position when you go back to printing on ordinary paper. 4-4 Paper Handling
