HELP! New Aio Printer Hates My UPS! Can anyone help?

This was originally posted on APC forums on 9/5/2007


Hello:

I am not a tekkie. So...please excuse the (perhaps) elementary nature of this post.
I have an ES500 Back up UPS.
All has been well until today when I plugged in my new All - In - One Samsung Laser Printer.

Until today, I was using an old-style HP LaserJet.

I must add that neither the new AIO nor the old LaserJet were/are plugged into the ES500, however they are
plugged into another wall outlet nearby. I realize you are not supposed to plug laser printers into the UPS.

The only two (2) things actually plugged into the ES500 are the CPU (EMachines basic unit) and a LCD monitor.

In case it makes a difference, the AIO is physically located quite close in proximity to the ES500.

Anyway...initially all was well..all the machines got along.....(like in the TERMINATOR movie)

After about ten or fifteen minutes of using the AIO machine....the ES500 started howling..and eventually shut down my computer.

This happened three times in a row (after varying relatively short periods of time).

So...now..I have disconnected the AIO machine until I can figure out how to make these machines co-exist with one another.

I am assuming that it is not a capacity issue....since this new AIO is rated at 5.5 amps and the old HP LaserJet was rated at 8.7 amps....
....further..the circuit breaker in my electrical panel did not trip in any of these episodes.

In reading the posts (from what I can understand) it seems like I may have an issue with distrortion effecting the elec. line or noise eminating from the
AIO machine.

I'd really prefer to NOT have to return this machine to the store....it seems like a really nice AIO....so.....can anyone shed some light here?

Do I need a filter of some sort? Do I need a more advanced UPS ?

All replies will be sincerely appreciated!!!!

Can you describe the howling? It is possible that the laser printer was causing a localized brownout on the circuit it shares with the UPS, and the UPS reacted by going to battery power. Since the ES500 is a relatively small UPS, and offers limited runtime, its possible that the UPS went to battery enough to deplete the battery, and cause a low runtime condition. This scenerio could have triggered your shutdown software (either PowerChute or the built in Windows UPS support - I'm assuming you are using Windows) to initiate a graceful shutdown.

If you are using PowerChute Personal Edition Software with your UPS, you may be able to look at the power history section, and see what the UPS was reacting to.
