Storing Print Media; Avoiding Jams - Lexmark W840 User Manual

Understanding paper and specialty media guidelines
Card stock
Card stock is single ply, and has a large array of properties, such as the moisture content, thickness, and texture, that can
significantly affect print quality. See Supported print media on page 35 for information on the preferred weight and for the
grain direction of print media.
Try a sample of any card stock you are considering using with the printer before purchasing a large quantity.
See Print media weights on page 40 for information on the preferred weight of media.
When printing on card stock:
• Set the Paper Type menu item in the Paper Menu to Card Stock from the operator panel, from the printer driver, or
from MarkVision Professional. Set the Paper Weight to CardStock Weight, and select the CardStock Weight as
Normal or Heavy for the value. Set this from the operator panel, the printer driver, or from MarkVision Professional.
Use Heavy for card stock weighing more than or heavier than 163 g/m
• Be aware that preprinting, perforation, and creasing can significantly affect the print quality and cause media
handling or jamming problems.
• Avoid using card stock that may release hazardous emissions when heated.
• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi-liquid and volatile components into the printer.
• The use of grain long card stock is recommended.

Storing print media

Use the following guidelines to avoid paper feeding problems and uneven print quality.
• For best results, store media in an environment where the temperature is approximately 21°C (70°F) and the
relative humidity is 40%.
Most label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with a relative
humidity of 40 to 60%.
• Store cartons of media on a pallet or shelf, rather than directly on the floor.
• When storing individual packages of media out of the original carton, make sure they rest on a flat surface so the
edges do not buckle or curl.
• Do not place anything on top of the media packages.
• Store paper in its original wrapper until you load it into the printer.

Avoiding jams

Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing. See
Supported print media on page 35 for more information.
Note: Try a limited sample of any print media you are considering using with the printer before purchasing
large quantities.
By selecting the appropriate print media and loading it properly, you can avoid most jams. For detailed tray loading
instructions, see the following:
