Safety Information
Product and Laser Safety
HP printers are UL 1950 listed, CSA 22.2 950 certified, and manufactured in accordance with DIN IEC 950. The printers are certified as “Class 1” laser products under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard, according to the Radiation Control for Health and Safety Act of 1968. The printers do not produce hazardous laser radiation.
Since radiation emitted inside the printer is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration implemented regulations for laser products on August 2, 1976. These regulations apply to laser products manufactured from August 1, 1976. Compliance is mandatory for products marketed in the United States.
N o t e |
In accordance with West German standard |
|
VDE0836 (VDE-Bestimmung fur die Elektrische |
|
Sicherheit von Lasergeraten und Anlagen), two |
|
servicemen are required to service each unit. |
Since the laser beam is invisible, the label on the following page is attached to the Laser Scanner Cover inside the printer where there is danger of exposure to laser radiation.
C a u t i o n |
Never service or operate the printer with the |
|
protective cover removed from the laser scanner |
|
assembly. The reflected beam, although invisible, |
|
can damage your eyes. |

LASERTURVALLISUUS
LUOKAN 1 LASERLAITE
KLASS 1 LASER APPARAT
HP LaserJet(s) 4/4M, 4 Plus/4M Plus laserkirjoitin on käyttäjän kannalta turvallinen luokan 1 laserlaite. Normaalissa käytössä kirjoittimen suojakotelointi estää lasersäteen pääsyn laitteen ulkopuolelle.
Kirjoittimen on hyväksynyt Suomessa laserturvallisuuden osalta Sähkötarkastuskeskus. Laitteen turvallisuusluokka on määritetty valtioneuvoston päätöksen N:o 472/1985 ja standardin EN 60825 (1991) mukaisesti.
VAROITUS ! Laitteen käyttäminen muulla kuin käyttöohjeessa mainitulla tavalla saattaa altistaa käyttäjän turvallisuusluokan 1 ylittävälle näkymättömälle lasersäteilylle.
VARNING ! Om apparaten används på annat sätt än i bruksanvisning specificerats, kan användaren utsättas för osynlig laserstrålning, som överskrider gränsen för laserklass 1.
HUOLTO HP LaserJet (s) 4/4M, 4 Plus/4M Plus-kirjoittimen sisällä ei ole käyttäjän huollettavissa olevia kohteita. Laitteen saa avata ja huoltaa ainoastaan sen huoltamiseen koulutettu henkilö. Tällaiseksi huoltotoimenpiteeksi ei katsota väriainekasetin vaihtamista, paperiradan puhdistusta tai muita käyttäjän käsikirjassa lueteltuja, käyttäjän tehtäväksi tarkoitettuja ylläpitotoimia, jotka voidaan suorittaa ilman erikoistyökaluja.
VARO !Mikäli kirjoittimen suojakotelo avataan, olet alttiina näkymättömälle lasersäteilylle laitteen ollessa toiminnassa. Älä katso säteeseen.
VARNING !Om laserprinterns skyddshölje öppnas då apparaten är i funktion, utsättas användaren för osynlig laserstrålning. Betrakta ej strålen.
Tiedot laitteessa käytettävän laserdiodin säteilyominaisuuksista:
Aallonpituus 770-795 nm
Teho 5 mW

Toner Safety
N o t e |
Toner may stain clothing. Skin and clothing are |
|
best cleaned by removing as much toner as |
|
possible with a dry tissue, then washing with cold |
|
water. Hot water causes toner to melt and |
|
permanently fuse into clothing. |
A Material Safety Data Sheet (MSDS) for the toner cartridge used in the HP printers, is available through Hewlett-Packard by either mail or fax.
Mail. To obtain a MSDS for the 92298A LaserJet Toner Imaging System through the mail, call the Customer Information Center (CIC) at 1-800-752-0900 between 6 A.M. and 5 P.M. Pacific Standard Time.
Fax. To obtain a MSDS for the 92298A LaserJet Toner Imaging System by fax, call the HP FIRST number at (800) 333-1917 (U.S. and Canada) and enter document number 1512.
N o t e |
To get documents from HP FIRST by fax, you |
|
must use a Group 3 (touchtone) fax machine. |
Ozone Statement
These printers do not use high voltage corona wires in the electro-photographic process, and therefore generate no measurable ozone gas (O3). They use a charging roller in the toner cartridge and a charging transfer roller in the printer.
