Storing Media - Lexmark C920 User Manual

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 Identifying media sources and specifications for information on the preferred weight
for the grain direction of media.
Try a sample of any card stock considered for use with the printer before purchasing a large quantity.
See Media types and weights 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 media

Use the following guidelines for proper media storage. These help avoid media 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.
