Laser notice
The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR, Chapter I, 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: 2014.
Class I laser products are not considered to be hazardous. The printer contains a Class IIIb (3b) AlGaInP laser
that is nominally 15 milliwatts operating in the wavelength region of 650–670 nanometers and enclosed in a
non-serviceable printhead assembly. 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
conditions.
Avis relatif à l'utilisation du laser
Cette imprimante est certifiée conforme aux exigences de la réglementation des Etats-Unis relative aux produits
laser de classe I (1) (DHHS 21 CFR, Chapitre I, Sous-chapitre J). Pour les autres pays, elle est certifiée conforme
aux exigences des normes CEI 60825-1: 2014 relatives aux produits laser de classe I.
Les produits laser de Classe I ne sont pas considérés comme dangereux. L'imprimante contient un dispositif
laser AlGaInP (aluminium, gallium, indium et phosphore) de classe IIIb (3b) d'une puissance nominale de
15 milliwatts fonctionnant dans la plage de longueurs d'onde allant de 650 à 670 nanomètres et scellé dans
un compartiment de têtes d'impression non réparable. Le système laser ainsi que l'imprimante ont été conçus
de manière à ce que personne ne soit jamais exposé à des radiations laser dépassant le niveau de classe I
dans le cadre d'un fonctionnement normal, de l'entretien par l'utilisateur ou de la maintenance.
Notificació
La impressora està certificada als EUA per complir els requeriments de DHHS 21 CFR, capítol I, subcapítol J
per a productes de làser Classe I (1), i a la resta del món s’ha certificat com productes de làser Classe I segons
els requeriments de la norma IEC 60825-1: 2014.
Els productes de làser Classe I no es consideren perillosos. La impressora conté un làser intern Classe IIIb (3b)
AlGaInP que normalment és de 15 miliwatts, que funciona a la regió de longitud d’ona de 650 a 670 nanòmetres
i es troba dins d’una unitat de capçals d’impressió no substituïble. El sistema làser i la impressora estan
dissenyats de manera que les persones no estiguin exposades a una radiació del làser superior al nivell de
Classe I durant el funcionament normal, el manteniment de l’usuari o les condicions de servei prescrites.

Aviso sobre laser
Esta impressora foi certificada nos EUA por estar em conformidade com os requisitos do DHHS 21 CFR capítulo
I, subcapítulo J, para produtos a laser de Classe I (1) e, nos demais países, foi certificada como um produto a
laser de Classe I em conformidade com os requisitos da IEC 60825-1: 2014.
Os produtos a laser de Classe I não são considerados prejudiciais. A impressora contém, internamente, um
laser de Classe IIIb (3b) AlGaInP que funciona nominalmente a 15 miliwatts no comprimento de onda de 650-670
nanômetros, incluso em um conjunto do cabeçote de impressão sem possibilidade de manutenção. O sistema
do laser e a impressora foram projetados para que jamais haja acesso humano à radiação do laser acima do
nível da Classe I durante a operação normal ou a manutenção pelo usuário ou sob as condições de manutenção
prescritas.
Avvertenze sui prodotti laser
La stampante è certificata negli Stati Uniti come prodotto conforme ai requisiti DHHS 21 CFR Capitolo I,
Sottocapitolo J per i prodotti laser di Classe I (1), mentre in altri paesi è certificata come prodotto laser di Classe
I conforme ai requisiti IEC 60825-1: 2014.
I prodotti laser di Classe I non sono considerati pericolosi. La stampante contiene internamente un laser AlGaInP
di Classe IIIb (3b) con valore nominale di 15 milliwatt, funzionante nella regione della lunghezza d'onda dei
650-670 nanometri e contenuto in un gruppo testina di stampa non riparabile. Il sistema laser e la stampante
sono stati progettati in modo da impedire l'esposizione a radiazioni laser superiori al livello previsto dalla Classe
I durante le normali operazioni di stampa, manutenzione o assistenza.
Laserinformatie
De printer is in de Verenigde Staten gecertificeerd als een product dat voldoet aan de vereisten van DHHS 21
CFR hoofdstuk 1, paragraaf J voor laserproducten van klasse I (1). Elders is de printer
laserproduct van klasse I dat voldoet aan de vereisten van IEC 60825-1: 2014.
Laserproducten van klasse I worden geacht geen gevaar op te leveren. De printer bevat intern een laser van
klasse IIIb (3b) AlGaInP met een nominaal vermogen van 15 milliwatt in een golflengtebereik van 650-670
nanometer in een niet-bruikbare printkopeenheid. Het lasersysteem en de printer zijn zodanig ontworpen dat
gebruikers nooit blootstaan aan laserstraling die hoger is dan het toegestane niveau voor klasse I-apparaten,
tijdens normaal gebruik, onderhoudswerkzaamheden door de gebruiker of voorgeschreven
servicewerkzaamheden.

CAUTION—SHOCK HAZARD: This product uses a soft power switch. It does not physically disconnect
the input AC voltage. To avoid the risk of electrical shock, always remove the power cord from the
printer when removal of the input AC voltage is required.
CAUTION—SHOCK HAZARD: To avoid the risk of electrical shock and to prevent damage to the printer,
remove the power cord from the electrical outlet and disconnect all connections to any external devices
before you connect or disconnect any cable, electronic board, or assembly.
CAUTION—HOT SURFACE: The inside of the printer might be hot. To reduce the risk of injury from a hot
component, allow the surface to cool before touching it.
CAUTION—PINCH HAZARD: To avoid the risk of a pinch injury, use caution in areas marked with this
label. Pinch injuries may occur around moving parts, such as gears, doors, trays, and covers.
Troubleshooting overview
Performing the initial troubleshooting check
Before you start the troubleshooting procedures, perform the following checks:
• Use genuine Lexmark supplies and parts for the best results. Third-party supplies or parts may aect the
performance, reliability, or life of the printer and its imaging components.
• With the power cord unplugged from the electrical outlet, check that the cord is free from the breakage,
short circuits, disconnected wires, or incorrect connections.
• Make sure the printer is properly grounded. Check the power cord ground terminal.
• Make sure the power supply line voltage is within 10% of the rated line voltage.
• Make sure the machine is securely installed on a level surface in a well‑ventilated area.
• Make sure the room temperature is between 16 and 32°C (60 and 90°F) and that the relative humidity is
between 20 and 80%.
• Avoid sites generating ammonia gas, high temperature, high humidity (near water faucets, kettles,
humidifiers), cold spaces, near open flames, and dusty areas.
• Avoid sites exposed to direct sunlight.
• Make sure the paper is the recommended paper for this printer.
• Make a trial print with paper from a newly opened package, and check the result.

Initial print quality check
Before troubleshooting print problems, perform the following:
• Make sure that the printer is located in an area that follows the recommended operating environment
and power requirement specifications.
• Check the status of supplies. Replace supplies that are low or empty.
• Load 20‑lb (75-80 g/m

• From the control panel, navigate to Settings > Tro ublesh ooting > Print Quality Test Pages.
• Print and keep the Menu Settings Page. The original page is used to restore the custom settings if
necessary.
• On the Menu Settings page, check if the print resolution is set to 600 dpi and the toner darkness is set
to Normal.
• Check the toner cartridges for damage, and replace if necessary.
• Make sure that the correct print driver is used to prevent print problems. If the wrong print driver is
installed, then incorrect characters could print and the copy may not fit the page correctly.
