Please forgive me if this is a repeat. I got some bounced mail from
my first posting that leads me to think it got scrozzled somehow...
This post was prompted by a previous post on laser writers having
spikes in power use. I have had experience with an Apple Personal
Laser Writer NT that causes lights on the same circuit to dim for a
fraction of a second every few seconds when it is on, as if it is
pulling a fairly large current (but not enough to trip the 10 amp fuse
on my surge-protector).
Is this normal?
Thanks.

There is a heater inside the fuser roller. (The fuser roller melts the toner (which is plastic) onto the paper) I have seen what you describe (lights dim) but generally only in buildings where the wiring is less than ideal. I have even had to move the laser printer to a differnt circuit sometimes when it causes computer crashes because of spikes. This again was in locations where wiring was completely inadequate. Something about computer installations in buildings that are >100 years old that always causes problems. tj
