LaserWriter: Amperage Fluctuations Caused by Fuser



My understanding is that an idle LaserWriter uses around 1.5 amps. I've
measured my LaserWriter and it sometimes draws as much as six amps. Is
this normal?

What you're probably picking up is the fuser turning on and off. The fuser
comes on about every 20 seconds and causes a jump in the amount of amps
used by the LaserWriter. This is not unusual and is nothing to worry about.
