Safety information

Toner safety

Handling and storage

WARNING! Keep toner cartridges and toner particles away from excessive heat, sparks, and open flames.

If toner is spilled, avoid breathing in toner particles. Inhalation of toner particles causes respiratory tract irritation. Vacuum or sweep the material into a bag or other sealed container. A vacuum specifically designed for cleaning toner can be used if it is capable of filtering fine particles (5 microns in diameter).

WARNING! Do not vacuum toner using a conventional vacuum. Toner particles used in this product might be too fine for effective vacuuming and could result in damage to a conventional vacuum.

Dispose of waste toner in accordance with local requirements. Do not discharge toner particles in drains.

First aid measures

lIngestion. If toner is ingested, rinse mouth out thoroughly with water and drink several glasses of water. Get medical attention if symptoms persist.

lInhalation. If toner particles are inhaled, move to fresh air immediately. If symptoms occur, consult a physician.

lEye contact. If toner comes in contact with the eyes, immediately flush with plenty of water for at least 15 minutes. If irritation persists, consult a physician.

lSkin contact. If toner spills on skin, remove as much toner as possible with a dry tissue, and then wash with cold water.

	Clothing contact
Note	Toner can stain clothing. Hot water or heat (from a clothes dryer) can cause toner to melt and
	permanently fuse to clothing.
	Clothing is best cleaned by removing as much toner as possible with a dry tissue, and then washing
	with cold water. Air-dry clothing.

Safety information 11

Laser safety

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has implemented regulations for laser products manufactured 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.

Because 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, bypassing safety switches, or performing procedures other than those specified in this service manual can result in exposure to hazardous radiation.

LED safety

The infrared port on the control panel of this printer is classified as a Class 1 LED (light emitting diode) device according to International Standard IEC 60825-1 (EN 60825-1). This device is not considered harmful, but the following precautions are recommended.

lAvoid direct eye exposure to the infrared LED beam.

lBe aware that the beam is invisible light and cannot be seen.

lDo not attempt to view the infrared LED beam with any type of optical device.

Environmental Product Stewardship Program

Protecting the environment

Hewlett-Packard Company is committed to providing quality products in an environmentally sound manner. This product has been designed with several attributes to minimize impacts on our environment.

Ozone production

This product generates no appreciable ozone gas (O3).

Energy consumption

Energy usage drops significantly while the printer is in PowerSave mode, which saves natural resources and saves money without affecting the performance of the printer. This product qualifies for ENERGY STAR ® which is a voluntary program established to encourage the development of energy-efficient office products.

ENERGY STAR ® is a U.S. registered service mark of the United States Environmental Protection Agency. As an ENERGY STAR ® partner, Hewlett-Packard Company has determined that this product meets the ENERGY STAR ® guidelines for energy efficiency. For more information, see

http://www.epa.gov/energystar/

Toner consumption

EconoMode uses significantly less toner, which might extend the working life of the toner cartridge.

Paper use

This product’s duplex feature (two-sided printing) and N-up printing capability (multiple pages printed on one sheet of paper) can reduce paper usage and the resulting demands on natural resources.

Plastics

Plastic parts more than 25 grams in weight are marked according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product’s life.

C7058-90936

Environmental Product Stewardship Program 13

HP LaserJet printing supplies

In many countries, this product’s printing supplies (for example: toner cartridge, drum, fuser) can be returned to HP through the HP Printing Supplies Returns and Recycling Program. An easy-to-use takeback program is available in more than 25 countries. Multilingual program information and instruction are included in every new HP LaserJet toner cartridge and consumables package.

HP Printing Supplies Environmental Program information

Since 1990, the HP Printing Supplies Returns and Recycling Program has collected more than 39 million used LaserJet toner cartridges that otherwise might have been discarded in the world’s landfills. The HP LaserJet toner cartridges and consumables go to a collection center and are bulkshipped to our resource and recovery partners who disassemble the cartridge’s for recycling. After a through quality inspection, selected parts 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.

US returns

For a more environmentally responsible return of used cartridges and consumables, HP encourages the use of bulk returns. Simply bundle two or more cartridges together and use the single, pre-paid, pre-addressed UPS label that is supplied in the package. For more information in the United States, call (1) [phone] or visit the HP LaserJet Supplies website at

http://www.ljsupplies.com/planetpartners/.

Outside the US returns

Outside the US customers should call the local HP sales and service office for further information regarding availability of the HP Supplies Returns and Recycling Program.

Paper

This printer is suited for the use of recycled papers when the paper meets the guidelines outlined in the HP LaserJet Printer Family Print Media Guide. Also, this printer is suitable for the use of recycled paper according to DIN 19309.

Material safety data sheet

Material Safety Data Sheets (MSDS) can be obtained by contacting the HP LaserJet Supplies website at http://www.hp.com/go.msds. In the United States, if you do not have access to the internet, call the U.S. HP FIRST (fax on demand service) at (1) [phone]. Use index number seven for a listing of the material safety data sheets. Outside the US, see “Worldwide offices“in table 8 for appropriate phone numbers and information.
