Energy and Certifications
Energy Saving Features For the most part, you can judge energy saving issues by the appropriate certifications, notably Energy Star, but there are at least two specifics you should also look for. First, an instant warm-up fuser will save energy by not having to warm up before printing, and as a nice bonus, it will speed first page out time. Similarly, for all-in-ones or multi-function printers, an instant on light source will both save energy and speed scanning. More important, an instant on light source usually goes hand in hand with a mercury-free lamp in the scanner, which is a hazardous substance that's best avoided.Finally, don't overlook the importance of certifications. In particular, look for Energy Star (for energy savings) and RoHs (for avoiding hazardous substances).
