Choosing Paper Envelopes-You can load envelopes as shown below. Load envelopes along the length of an envelope. The printing quality on envelopes may be irregular because different parts of an envelope have different thicknesses. 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. Also, for better printing of envelopes, use the optional face-up output tray. Other materials -- You can use overhead projector transparencies and adhesive drafting film if they are made for use with plainpaper copiers or laser printers. When printing these materials, use the optional face-up output tray for best results. 4-4 Paper Handling
