Laser notices

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.
Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) laser that is nominally a 15milliwatt laser operating in the wavelength of 787–800 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-Hinweis
Der Drucker wurde in den USA zertifiziert und entspricht den DHHS-Vorschriften 21 CFR, Kapitel I, Unterkapitel J für Laserprodukte der Klasse I (1); andernorts ist er als Laserprodukt der Klasse I zertifiziert, das den IEC 60825-1­Anforderungen entspricht.
Laserprodukte der Klasse I werden nicht als gefährlich eingestuft. Der Drucker enthält im Inneren einen Laser der Klasse IIIb (3b), und zwar einen 15-Milliwatt-Laser, der im Wellenlängenbereich von 787 bis 800 Nanometern arbeitet. Das Lasersystem und der Drucker sind so konstruiert, dass unter normalen Betriebsbedingungen, bei der Wartung durch den Benutzer oder bei den vorgeschriebenen Wartungsbedingungen Menschen keiner Laserstrahlung ausgesetzt sind, die die Werte für Klasse I überschreitet.
Avis relatif à l'utilisation du laser
L'imprimante est certifiée conforme aux exigences de la réglementation des Etats-Unis relative aux produits laser (DHHS 21 CFR, Chapter I, Subchapter J for Class I (1)). Pour les autres pays, elle est certifiée conforme aux exigences des normes IEC 60825-1 relatives aux produits laser de classe I.
Les produits laser de Classe I ne sont pas considérés comme dangereux. L'imprimante contient un laser de classe IIIb (3b), laser 15 milliwatts opérant sur une longueur d'onde de l'ordre de 787 à 800 nanomètres. Le système laser ainsi que l'imprimante ont été conçus de manière à ce que personne ne soit exposé à des rayonnements laser dépassant le niveau de classe I dans le cadre d'un fonctionnement normal, de l'entretien par l'utilisateur ou de la maintenance.
Avvertenze sui prodotti laser
La stampante è certificata negli Stati Uniti come stampante 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.
I prodotti laser di Classe I non sono considerati pericolosi. La stampante contiene un laser di Classe IIIb (3b), che è nominalmente un laser a 15 milliwatt funzionante a una lunghezza d'onda di 787–800 nanometri. 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
Deze 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 gecertificeerd als een laserproduct van klasse I dat voldoet aan de vereisten van IEC 60825-1.
Laserproducten van klasse I worden geacht geen gevaar op te leveren. De printer bevat intern een laser van klasse IIIb (3b), met een nominaal vermogen van 15 milliwatt en een golflengtebereik van 787–800 nanometer. 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.
Lasererklæring
Denne printer er certificeret i USA i henhold til kravene i DHHS 21 CFR, afsnit I, underafsnit J, for Klasse I-laserprodukter (1) og certificeret andetsteds som et Klasse I-laserprodukt i henhold til kravene i IEC 60825-1.
Klasse I-laserprodukter anses ikke for at være farlige. Printeren indeholder internt en klasse IIIb (3b)-laser, der nominelt er en 15 milliwatt laser, som fungerer i bølgelængdeområdet 787–800 nanometer. Lasersystemet og printeren er udviklet på en sådan måde, at der ikke er en direkte laserstråling, der overskrider Klasse I-niveauet under normal brug, brugers vedligeholdelse eller de foreskrevne servicebetingelser.
Laserilmoitus
Tämä tulostin on sertifioitu Yhdysvalloissa DHHS 21 CFR, Chapter I, Subchapter J -standardin mukaiseksi luokan I (1) ­lasertuotteeksi ja muualla IEC 60825-1 -standardin mukaiseksi luokan I lasertuotteeksi.
Luokan I lasertuotteita ei pidetä haitallisina. Tulostimen sisällä on luokan IIIb (3b) laser, joka on nimellisteholtaan 15 mW:n laser ja toimii 787–800 nanometrin aallonpituuksilla. Laserjärjestelmä ja tulostin ovat rakenteeltaan sellaisia, että käyttäjä ei joudu alttiiksi luokkaa 1 suuremmalle säteilylle normaalin käytön, ylläpidon tai huollon aikana.

Paper and specialty media guide

Notes:
Make sure that the paper size, type, and weight are set correctly on the computer or control panel.
Flex, fan, and straighten specialty media before loading them.
The printer may print at a reduced speed to prevent damage to the fuser.
For more information on card stock and labels, see the Card Stock & Label Guide at
http://support.lexmark.com.

Using specialty media

Tips on using card stock
Card stock is heavy, singleply specialty media. Many of its variable characteristics, such as moisture content, thickness, and texture, can significantly affect print quality.
From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the card
stock loaded in the tray.
Print samples on the card stock being considered for use before buying large quantities.
Specify the paper texture and weight from the tray settings to match the paper loaded in the tray.
Preprinting, perforation, and creasing may significantly affect the print quality and cause jams or other paper feed
problems.
Before loading the card stock on the tray, flex and fan the card stock to loosen them. Straighten the edges on a
level surface.
Tips on using envelopes
From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the
envelopes loaded in the tray.
Print samples on the envelopes being considered for use before buying large quantities.
Use envelopes designed specifically for laser printers.
For best performance, use envelopes made from 90g/m
General information
2
(24lb) paper or 25% cotton.
29
Use only new envelopes from undamaged packages.
To optimize performance and minimize jams, do not use envelopes that:
Have excessive curl or twist.
Are stuck together or damaged in any way.
Have windows, holes, perforations, cutouts, or embossing.
Have metal clasps, string ties, or folding bars.
Have an interlocking design.
Have postage stamps attached.
Have any exposed adhesive when the flap is in the sealed or closed position.
Have bent corners.
Have rough, cockle, or laid finishes.
Adjust the width guides to fit the width of the envelopes.
Before loading the envelopes on the tray, flex the stack of envelopes back and forth to loosen them, and
then fan them. Straighten the edges on a level surface.
Note: A combination of high humidity (over 60%) and high printing temperature may wrinkle or seal envelopes.
4021
Tips on using labels
From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the labels
loaded in the tray.
Print samples before buying large quantities.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide at
http://support.lexmark.com.
Use labels designed specifically for laser printers.
Do not use labels with slick backing material.
Do not use labels with exposed adhesive.
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets
also contaminate the printer and the cartridge with adhesive, and could void the printer and toner cartridge warranties.
Before loading labels on the tray, flex and fan labels to loosen them. Straighten the edges on a level surface.
Tips on using letterhead
Use letterhead specifically for laser printers.
Print samples before buying large quantities.
Before loading letterhead, flex and fan the sheets.
When printing on letterhead, take note of the page orientation.
