Wow open your ears and learn
Usually anything on a share you can check with your meter
Decated line mean decated . I assume you know how to use one. Or if your company has a power tracker that monitors the device. Yes it's that easy
We also had one on a dedcated line that would power off brand new machine I monitor the line voltage and would drop to 100volts and machine would turn off. Turned out it the neutral line was not tighten down..
Problem solved
Oh, maybe it ISN'T on a dedicated circuit!

We had another one "back in the day", late 90's. Another school. Customer said machine would reboot. Of course the tech couldn't find any issue with the machine.
Just happened that a tech was there during class change and it did it. On the other side of the wall was a boys bathroom that had recently installed a HOT air dryer.
Yep, that was it!👍 1Leave a comment:

We have a school system and all of a sudden (about the time it started getting COLD outside) they complained about a 65ppm color machine (20amp) that starts firing off
fuser errors. Tech replaced the fuser unit and a few days later it did it again. I told him to check the AC socket for a neutral-ground voltage. Also asked if it has an ESP filter
on the circuit and he said yes. Brought it in and I checked. Had over 100 entries in the last 9 months. About 30 for a month. Most were surge/drop outs. This ESP didn't have
the neutral to ground because it was an older one. Tech went back, showed them the printout and he checked the N-G and when the machine was running it was spiking OVER
four volts! He told them to have an electrician check the circuit to make sure it was a dedicated outlet.
Couple days later they said the machine did it again, electrician said the outlet was good bla bla bla.
Couple more yes it is, no it isn't and then one of my supervisor techs went there and had the school electrician with him and he said after seeing the N-G voltage, "oh, looks like
you have a common mode issue" (tech's jaw hit the floor when he said that...DUH! someone gets it).
But the school said it wasn't a problem, so, we pulled a like machine from the other side of the school that service history showed NO issues, and swapped the machines.
NEXT day the machine that has NEVER had a problem, had the same fuser code as the original machine.
And here's the kicker. The school said "oh, well maybe that outlet isn't a dedicated line?" YA THINK?
Most likely some "Susie secretary" doesn't like the cold, plugged in her space heater and is pulling a bit too much juice.
That, or the wiring in the building needs to be replaced.
THIS is why my hair is gray!
I liked the way you handled the situation. I don't think you could have handled it any better.

An electrical diagram of the building would be nice, if its still accurate.Leave a comment:

In the early days of the RBC 1, the West Coast Royal dealer support tech told me a story about an incident one of his other dealers had encountered. The breaker for the circuit the RBC has on kept tripping but nothing else was affected. It turned out that the wall outlet circuits in that building were single outlets on multiple floors and a secretary 2 floors below had an electric space heater under her desk.Leave a comment:

Pretty easy to tell if on a decated .line trip the breaker and see what else turns off👍 1😎 1Leave a comment:

Good gravy. It's that time of year again isn't it?
I had a similar story once. However, they were plugging their space heater into the same outlet as the UPS on the server rack.... via an extension cord from the office.... Every time the secretary got cold the breaker would trip, the UPS would drain, and the entire network would go down. Arg!👍 1Leave a comment:
