Laser printer sometimes trips an APC and shuts off computer??

@Mike-Davis said in Laser printer sometimes trips an APC and shuts off computer??:
When the printer tries to heat up the fuser from being in power save mode, it probably causes a voltage drop on that circuit.
It sounds like the battery in your UPS is shot or something. If it's more than 3 years old just replace it. If you have the PowerChute software (or what ever it is for your model) you can run a load test and see if the battery can carry the load.
^This, usually happens all the time. I am going to disagree with some other comments about APC being just cheap, any other battery backup that is on 350 VA-1000VA will do the same when there is a printer plugged into the powersurge section of the battery backup. That is why all our printers are either plugged into a line conditioner or powersurge separated from a battery backup.
No matter if it is Eaton, APC, Cyberpower, Tripplite the result have been the same with multiple customers having the same issue when they decide to plug it to the battery backup surge portion.

Would you all stop fucking saying shit that is not damned true.
@guyinpv clearly stated IN THE FIRST POST, that the printer is not in the UPS.

@JaredBusch Still is on the freaking same circuit...

Yes, and that should have zero effect on a quality UPS.
-
@JaredBusch So you are saying Eaton would be the solution correct? I am assuming you would not recommend a 750 VA from Eaton on this specific situation?

I trust Eaton hardware over APC any day.
But even a brand new APC unit would likely not have these problems here. They typicaly last a yearish before having issues.

But are you talking about this: http://powerquality.eaton.com/3S750.aspx?cx=3?
I would never recommend it for anything.

I am actually buying 35 Eaton battery backups this month so it is good to hear on that. I am replacing some APCs here.

I would only buy the 5S or better series.

@JaredBusch Good to know, let me check them out.

I guess if you honestly do not care about the user, the 3 series is ok. PC, monitor, and desk phone only things on it.
Just consider it a glorified surge protector that hold power for a minute, not a battery backup.
-
@JaredBusch But the 5S is not much different in price so using a 3S is of not benefit when price is the same...

Voltage regulation is the biggest thing IMO.
-
@JaredBusch Yes, that is big.
-
I assume voltage regulation is the root of my issue then. The laser printer caused "something" that the battery is not designed or quick enough to handle.
The only weird thing is that it doesn't happen most of the time. About once in every 50 prints maybe more.
-
To troubleshoot, if you get a voltmeter, make sure to use an old analog one. The voltage dip may be too quick for a digital one to detect. With a good analog one, you can watch the needle drop for a second if there is a quick dip.

That's my guess.
-
Well it happened again.
Ordered an Eaton 5S700. Might as well give it a shot.

Never using a UPS on a laser printer is probably the only useful thing I learned in A+.....

Right. Isn't that in UPS 101?
