An industry first, HP Auto-On/Auto-Off Technology automatically turns off the device to help individuals and businesses conserve energy. The U.S. Environmental Protection Agency estimates that customers waste up to 66% of energy related to equipment use by leaving devices on during nights and weekends.
The Auto-On feature turns the printer to full power when a user sends a print job, pushes the power button, or opens a paper tray. After the printer has been idle for a period of time, the Auto-Off feature turns the device off. High-end HP devices turned off using HP Auto-Off Technology consume up to 26 times less energy than most printers and multifunction products on the market in traditional sleep mode, helping users save money and reduce energy use and associated greenhouse gas emissions.
HP LaserJet products with Instant-on Technology use an innovative, quick-heating fuser system that warms rapidly and cools quickly. This, coupled with energy-efficient toner, helps users consume less printing-related energy, compared with using printers that don't have this technology.
Considering that HP ships two PCs and two printers every second, the savings add up. HP estimates that for monochrome LaserJet products alone, Instant-on Technology helped customers collectively avoid 1.3 million tonnes of carbon dioxide equivalent emissions in 2009, equivalent to removing more than 240,000 cars from the road for one year.
