Use letterhead designed specifically for laser printers.
Print samples on the letterhead being considered for use before buying large quantities.
Before loading letterhead, fan the stack to prevent sheets from sticking together.
Page orientation is important when printing on letterhead. For information on how to load letterhead, see:
Print samples on the transparencies being considered for use before buying large quantities.
When printing on transparencies:
Feed transparencies from the standard 250-sheet tray or the manual feeder.
Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure transparencies are able to withstand temperatures up to 190°C (374°F) without melting, discoloring, offsetting, or releasing hazardous emissions.
| Note: Transparencies can be printed at a temperature up to 200°C (392°F) if Transparency Weight is set to Heavy and Transparency Texture is set to Rough. If the transparencies you are using can withstand that temperature, select those settings using the Embedded Web Server, or from the printer control panel Paper menu. |
To prevent print quality problems, avoid getting fingerprints on the transparencies.
Before loading transparencies, fan the stack to prevent sheets from sticking together.
We recommend Lexmark part number 70X7240 for letter-size transparencies and Lexmark part number 12A5010 for A4-size transparencies.
Print samples on the envelopes being considered for use before buying large quantities.
When printing on envelopes:
Load envelopes from the manual feeder.
Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the envelopes can withstand temperatures up to 210°C (410°F) without sealing, wrinkling, curling excessively, or releasing hazardous emissions.
For the best performance, use envelopes made from 90 g/m2 (24 lb bond) paper or 25% cotton bond. Use up to 105 g/m2 (28 lb bond) weight for envelopes as long as the cotton content is 25% or less. All-cotton envelopes must not exceed 90 g/m2 (24 lb bond) weight.
The minimum supported weight for envelopes is 75 g/m2 (20 lb bond). For non-peel strip, self-seal envelopes, the minimum supported weight is 80 g/m 2 (21 lb bond).
Use only new envelopes.
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
Have rough, cockle, or laid finishes
Adjust the width guides to fit the width of the envelopes.
| Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal envelopes. |
Print samples on the labels being considered for use before buying large quantities.
| Note: Use only paper label sheets. Vinyl, pharmacy, and dual-sided labels are not supported. |
For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com/publications.
When printing on labels:
Use labels only in the paper tray or manual feeder. Do not use labels in the ADF.
Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
The labels can withstand temperatures up to 225°C (437°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions.
| Note: Labels can be printed at the highest fusing temperature if Label Weight is set to Heavy. Select this setting from the Embedded Web Server or from the printer control panel Paper menu. |
Label adhesives, face sheet (printable stock), and topcoats can withstand up to 25 psi (172 kPa) pressure without delaminating, oozing around the edges, or releasing hazardous fumes.
Do not use labels with slick backing material.
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and cartridge warranties.
Do not use labels with exposed adhesive.
Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label.
Be sure adhesive backing does not reach to the sheet edge. Zone coating of the adhesive at least 1 mm (0.04 in.) away from edges is recommended. Adhesive material contaminates the printer and could void the warranty.
If zone coating of the adhesive is not possible, remove a 1.6 mm (0.06 in.) strip on the leading and driver edge, and use a non-oozing adhesive.
Portrait orientation works best, especially when printing bar codes.
Card stock is heavy, single-ply specialty media. Many of its variable characteristics, such as moisture content, thickness, and texture, can significantly impact print quality. Print samples on the card stock being considered for use before buying large quantities.
When printing on card stock:
Make sure the Paper Type is Card Stock.
Select the appropriate Paper Texture setting.
Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams or other paper handling problems.
Check with the manufacturer or vendor to ensure the card stock can withstand temperatures up to 210°C (410°F) without releasing hazardous emissions.
Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting introduces semi-liquid and volatile components into the printer.
Use grain short card stock when possible.
