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.

Laser

Der Drucker erfüllt gemäß amtlicher Bestätigung der USA die
Anforderungen der Bestimmung DHHS (Department of Health and

In anderen Ländern gilt der Drucker als Laserprodukt der Klasse I,
der die Anforderungen der IEC (International Electrotechnical
Commission) 825 gemäß amtlicher Bestätigung erfüllt.

Laserprodukte der Klasse I gelten als unschädlich. Im Inneren des
Druckers befindet sich ein Laser der Klasse IIIb (3b), bei dem es
sich um einen Galliumarsenlaser mit 5 Milliwatt handelt, der Wellen
der Länge 770-795 Nanometer ausstrahlt. Das Lasersystem und der
Drucker sind so konzipiert, daß im Normalbetrieb, bei der Wartung
durch den Benutzer oder bei ordnungsgemäßer Wartung durch den

I prodotti laser di classe non sono considerati pericolosi. La
stampante contiene al suo interno un laser di classe IIIb (3b)
all’arseniuro di gallio della potenza di 5mW che opera sulla
lunghezza d’onda compresa tra 770 e 795 nanometri. Il sistema
laser e la stampante sono stati progettati in modo tale che le
persone a contatto con la stampante, durante il normale
funzionamento, le operazioni di servizio o quelle di assistenza
tecnica, non ricevano radiazioni laser superiori al livello della classe

2. Diagnostic Information

Start

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.
