The Physics of Color Lasers
A physicist is taking the teaching of Benjamin Franklyn on the science of electrostatics to improve color laser printers. According to Lawrence Schein, the physics of electrostatic adhesion -- concerning how charged particles stick to each other -- can make laser toner work more efficiently. Lower adhesion toner will make it possible to more easily build color images onto a single belt (rather than using more than one belt, as today's color lasers use). At least, a company called Aetas Systems, Inc., hopes to try it to build smaller and less expensive color laser. Keep an eye on this one.
