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 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 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.

CAUTION:
interlock switch and the printhead shutter actuator at the same
time. To perform some of the service checks and tests, such as
troubleshooting paper feed problems, you need to actuate the top
cover interlock switch with the co vers opened or remo ved and pow er
applied to the machine. It is important for personal safety that you
DO NOT, FOR ANY REASON
when power is on.
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 service error code, user error message, symptom table,
service checks, and diagnostic aids in this chapter to determine the
corrective action necessary to repair a malfunctioning printer.
The lights on the operator panel can indicate either a user error
message or service error message. When a service error occurs the
printer stops printing and all operator panel LEDs blink in a
continuous pattern, indicating a service error, until the printer is
powered off. If all operator panel LEDs are blinking, go to the
“Service Error Codes” on page 2-2.
When a user error message occurs, one or two operator panel LEDs
are on solid or blinking. Go to the “User Error Message Table” on
page 2-6.
NEVER
manually actuate or disable the top cover
, disable the printhead shutter actuator
If your machine does not have a service error code and does not
complete POST, go to the “POST Symptom Table” on page 2-12. If
your machine completes POST without an error, and you have a
symptom, go to the “Symptom Table” on page 2-13. 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.
