FCC compliance

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy. If it is not installed and
used in accordance with the instructions, it may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or tele vision
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase separation between equipment and receiver.

• Connect equipment to an outlet on a circuit different from that to which the receiver is
located.

• Consult your dealer or an experienced radio/TV technician.

NOTE: Any changes or modifications to the printer that are not expressly approved b y HP could void

the user’s authority to operate this equipment.
Use of a shielded interface cable is required to comply with the Class B limits of Part 15 of

FCC rules.

Paper use

Depending on the type of software program in use, y ou can request for a n umber of pages of
your document to be printed on one page of paper. This N-up printing practice and the
printer’s manual duplexing feature, which provides two-sided printing, can reduce paper

The design of this HP LaserJet printer facilitates the recycling of:

Plastics

Plastic housing parts have markings according to international standards that enhance the
ability to identify plastics for recycling purposes at the end of the printer’s life.

HP LaserJet printing supplies

In many countries, this product's printing supplies (e.g., toner cartridge, drum, fuser) can be
returned to HP through the HP Planet Partners Printing Supplies Environmental Program.
An easy-to-use takeback component of the program is available in over 20 countries. Multi­lingual program information and instructions are included in every new HP LaserJet Toner
Cartridge and Consumables box.

HP Planet Partners printing supplies environmental program information

Since 1990, the HP LaserJet Toner Cartridge Recycling Program has collected more than
12 million used HP LaserJet toner cartridges that otherwise may have been discarded in the
world's landfills. The HP LaserJet toner cartridges go to a collection center and are bulk
shipped to our recycling partners who disassemble the cartridge parts for recycling. After a
thorough quality inspection, minor parts such as nuts, screws, and clips are reclaimed for
use in new cartridges. Remaining materials are separated and converted into raw materials
for use by other industries to make a variety of useful products. For more information in the
U.S., call 1-800-340-2445 or visit the HP LaserJet Supplies website at:

Laser safety statement

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration has implemented regulations for laser products manuf actured since August 1,

1976. Compliance is mandatory for products marketed in the United States. The printer is

certified as a “Class 1” laser product 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.

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.

WARNING! Using controls, making adjustments, or performing procedures other than those specified in

this user’s guide may result in exposure to hazardous radiation.

LASERTURVALLISUUS

LUOKAN 1 LASERLAITE

KLASS 1 LASER APPARAT

HP LaserJet 1100 Printer -laserkirjoitin on käyttäjän kannalta turvallinen luokan 1 laserlaite.
Normaalissa käytössä kirjoittimen suojakotelointi estää lasersäteen pääsyn laitteen
ulkopuolelle.

Laitteen turvallisuusluokka on määritetty standardin EN 60825-1 (1993) 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 1100 Printer -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.

HP LaserJet 1100 Printer control panel

Hardware overview

The HP LaserJet 1100 Printer’s Control Panel consists of tw o LEDs and a Go ke y containing
a third LED. There is one amber LED (the Attention LED), and two green LEDs (the Ready
LED and the Go LED). The green LEDs are contained in the Go key. If the scanner is
attached, there are two additional buttons. Scanner modes are not shown on the printer
LEDs and scan keys have no effect on printer functionality.

Go key

The HP LaserJet 1100 Printer Control Panel’ s single Go k e y will be the only means the user
has of interacting with the printer, except through software. Therefore, the Go key must
perform all actions the user needs. The Go key performs ten functions. These functions are
explained in the table below. See “Scanner control panel” on page 31.
