Lexmark CS720 User Manual

To help avoid paper jams and poor print quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is usually
indicated on the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same tray; mixing results in jams.
• Do not use coated papers unless they are specifically designed for electrophotographic printing.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent.
Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative
humidity between 40 and 60 percent.
• Store paper in cartons, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
• Do not store anything on top of individual paper packages.
• Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and
wrapper help keep the paper clean, dry, and flat.

Tips on using envelopes
• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the
envelopes loaded in the tray.
• Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed specifically for laser printers.
• For best performance, use envelopes made from 90‑g/m
2
(24‑lb) paper or 25% cotton.
• Use only new envelopes from undamaged packages.
• To optimize performance and minimize jams, do not use envelopes that:
– Have excessive curl or twist.
– Are stuck together or damaged in any way.
– Have windows, holes, perforations, cutouts, or embossing.
– Have metal clasps, string ties, or folding bars.
– Have an interlocking design.
– Have postage stamps attached.
– Have any exposed adhesive when the flap is in the sealed or closed position.
– Have bent corners.
– Have rough, cockle, or laid finishes.
• Adjust the width guides to fit the width of the envelopes.
• Before loading the envelopes on the tray, flex the stack of envelopes back and forth to loosen them, and
then fan them. Straighten the edges on a level surface.
