Toner consumption Depending on the type of printer driver you have, you may be able to select a "draft" mode which uses about 50% less toner, thereby extending the life of the toner cartridge. This is only available using printer driver properties when printing or making copies from the software. Paper use Depending on the type of program you use, you may be able to print 2 or 4 document pages on each printed page. This "N-up" printing practice and the printer's manual duplex capability (two-sided printing) reduce paper usage and the resulting demands on natural resources. The design of this HP LaserJet printer facilitates the recycling of: Plastics Plastic parts have marking according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product's life. The plastics used in the product housing and chassis are technically recyclable. HP toner cartridges/photoconductive drum In many countries, this product's toner cartridge/drum can be returned to HP using the prepaid shipping label and instructions included inside each new HP toner cartridge box. If your country is not listed in the recycling guide, call your local HP Sales and Service Office (see appendix B) for further instructions. HP cartridge recycling program Since 1990, the HP LaserJet Toner Cartridge Recycling Program has collected more than 12 million cartridges that otherwise would have been discarded into landfills or similar facilities. Once a cartridge is returned through the prepaid return program, it is disassembled, and reusable components and the plastic housing are cleaned and inspected for quality conformance. After passing strict inspection procedures, materials such as nuts, screws, and clips are reclaimed and used to produce new cartridges. Remaining materials are melted down and used as raw materials for a variety of other products. Over 95 percent (%) of the weight of returned materials is recycled.
