>Does this problem machine have it's own UPS? We've run into problems at customer sites where the power coming from the wall was inconsistant (103 volts to 114 volts). When low voltage occured, there would be many seemingly random errors. (Their power was so bad at this site, that the lights flickered when the phones rang!) A UPS (on each machine) cured all of these problems.

Fred,
I insisted that it was an electrification problem but all measurements were same as neighboring rooms :( Even grounding was in limits.
