[sdiy] OT: my lights are blinking!?!?

[CHoaglin at aol.com]

I just hauled home a free color laser printer today from a local company..a 
Tek Phaser 550. I'm getting some strange behavior now from all the lights in 
the house, namely:

Every single light in the house noticeably flickers/blinks at about 4hz, if 
the motor/fuser are on...Usually this sort of thing happens with vacuum 
cleaners etc when starting the motor..momentary voltage drop due to increased 
current draw. I would normally expect this to only happen on the circuit that 
the equipment is being run on, rather than throughout the house, and I'm 
pretty sure the vacuum only makes this show up on one circuit. Now, I am 
using the printer, which is rated 10 amps worst case, on a 15 or 20 amp 
circuit along with 2 computers, 2 monitors, a VCR, and a mixing board. So, 
I'm probably pushing the limits of the circuit..could it be a line noise 
issue, or should I just find a sturdier circuit to put the printer on?
