Hi,
Does your light dim when your fridge kicks in or you use mirowave oven,
etc.? UPS = uninterrupted power supply, what makes you think UPS is
helpful? Maybe your place's wiring is at the borderline approaching max
capacity and that extra load printer is it. Laser printer has
fuser(heater which draws some current when printing).

Hi, no my fridge and microwave don't cause the lights to dim. In the
bathroom, the hair dryer does cause the lights to dim but only in that
room.

My rational for the UPS solution was that since the printer runs at
450 watts when printing, then, say a 600 watt (1000VA) UPS battery
would act as a buffer during the high load times. Doesn't this make
sense?

Hi,
It may help since it is on float charging battery situation. I'd try the
printer in several different outlet to really isolate it. Plug it in and
print a test page or sosmething.- Hide quoted text -

Something weird. A hair dryer or electric kettle or a toaster each
take more than twice that 450 watt rating. A UPS without finding out
the real cause sounds like an expensive solution, possibly bypassing
finding the real cause of a potentially dangerous situation?
