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 825.
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 wavelengthregion 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.

CAUTION: Remove power from the printer before you connect or
disconnect any cable or electronic board or assembly for personal
safety and to prevent damage to the printer. Use the hand grips on
the side of the printer. Make sure your fingers are not under the
printer when you lift or set the printer down.
Use the service error code, user status message, user error
message, symptom table, service checks, and diagnostic aids in this
chapter to determine the corrective action necessary to repair a
malfunctioning printer.
Service error codes are indicated by a three digit error code. If a
service error code is displayed, go to the “Service Error Codes” on
page 2-2.
User status messages provide the user with information on the
current status of the printer. Ready is displayed on the first line of the
display unless Power Saver is invoked, then Power Saver is
displayed. If a user status message is displayed, go to the “User
Status Messages” on page 2-12.
User error messages are indicated by a two or three digit error code
that provides the user with information that explains a problem with a
print cartridge, paper jam, option, port, and so on. If a user error
message is displayed, go to the “User Error Messages” on
page 2-16.
If your machine completes the “Power-On Self Test (POST)” on
page 2-24 without an error, and you have a symptom, go to the
“Symptom Tables” on page 2-25. Locate your symptom and take the
appropriate action.
If a service error code appears while you are working on the
machine, go to the “Service Error Codes” on page 2-2 and take the
indicated action for that error.
