Laser notice
The printer is certified 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 wav elength 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.

then remove any jams.

assembly.
3. Remove any jams located in the area behind the print
cartridge assembly.
4. Lift the flap at the front of the printer and remove any jams
located beneath the flap.
5. Open the rear exit and remove any jams.
6. After you have cleared the jams, reinstall the print cartridge
assembly, make sure all printer covers and trays are closed, and
then press the button to resume printing.

Tips on preventing jams
You can avoid most paper jams by correctly loading paper and
specialty media.
The following hints can help yo u 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 sn ugly against
the paper or specialty media.

from sticking together.

POST functioning of the base printer by observing the following
process:
1. All operator panel lights flash irregularly for approximately
10 seconds.
2. If there is a problem in the printer such as a paper jam, the
panel lights indicate the problem. See “Common light
sequences” on page 2-3 for more information.
3. Otherwise, the light flashes until the fuser comes up to
temperature (5–20 additional seconds depending on the initial
temperature of the fuser).
