Laser notice
The printer is cert ified in the U.S. to conform to the requirements of
DHHS 21 CFR Subchapter J for Class I (1) laser products, and
elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 60825-1.
Class I laser products are not considered to be hazardous. The
printer contains internally a Class IIIb (3b) laser that is nominally a 5
milliwatt gallium arsenide laser operating in the wavelength region of
770-795 nanometers. The laser system and printer are designed so
there is never any human access to laser radiation above a Class I
level during normal operation, user maintenance, or prescribed
service condition.

Tips on preventing jams
You can avoid most paper jams by correctly loading paper and
specialty media.
The following hints can help you avoid paper jams:
• Do not load wrinkled, creased, or damp paper.
• Never mix media types within a tray.
• Flex, fan, and straighten paper before you load it.
• Do not exceed the maximum stack height.
• Push all trays firmly into the printer after loading them.
• Make sure the guides in the trays are positioned snugly against
the paper or specialty media.
• Do not remove paper trays while a job is printing. Wait for a
Load Paper light sequence before you remove the tray.
• 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 embossing
– Use 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 paper. Refer to the Card Stock & Label
Guide available on the Lexmark Web site at www.lexmark.com for
more information about which paper provides optimum results for
current printing environment.
