Paper jams
Avoiding jams
Most paper jams can be avoided by correctly loading paper and specialty media in the printer.
The following hints can help prevent paper jams:
• Use only the recommended print media.
• Do not overload the print media sources. Make sure the stack height does not exceed the maximum height
indicated by the stack line on the labels in the sources.
• Do not load wrinkled, creased, damp, or curled print media.
• Flex, fan, and straighten print media before loading it. If jams do occur with the print media, then try feeding
one sheet at a time through the manual feeder.
• Do not mix print media sizes, weights, or types in the same print media source.
• Push all trays in firmly after loading them.
Note: Make sure the media stack is below the maximum media fill indicators on the 250-sheet tray before
pushing the tray into the printer.
• Make sure paper guides are positioned before loading the paper or specialty media.
• Do not remove trays while a job is printing.
• Before loading transparencies, fan the stack to prevent sheets from sticking together.
• Do not use envelopes that:
– Have excessive curl
– Are stuck together
– Are damaged in any way
– Contain windows, holes, perforations, cutouts, or embossments
– Have metal clasps, string ties, or metal folding bars
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed position
• Use only recommended media. Refer to the Card Stock & Label Guide available on the Lexmark Web site
at www.lexmark.com for more information about which media provides optimum results for the current
printing environment.
