Finally, the printer passes the paper through the fuser, a pair of heated rollers. As the paper passes through these rollers, the loose toner powder melts, fusing with the fibbers in the paper. The fuser rolls the paper to the output tray, and you have your finished page. The fuser also heats up the paper itself, of course, which is why pages are always hot when they come out of a laser printer or Photocopier.
So what keeps the paper from burning up? Mainly, speed — the paper passes through the rollers so quickly that it doesn’t get very hot.
