Sorry I don't think I explained this well. The printer is plugged directly into the wall not the UPS. The UPS certainly couldn't handle the printer. But the UPS and the printer use the same socket which has two outlets.
X - Printer X - UPS with everything else (forgot to mention also have a 22inch Acer LCD monitor in the UPS) I will get an extension cord and plug the printer in elsewhere for a test and see what that does. I'll keep you posted. -----Original Message----- From: hardware-boun...@hardwaregroup.com [mailto:hardware-boun...@hardwaregroup.com] On Behalf Of DSinc Sent: Sunday, February 14, 2010 10:07 AM To: hardware@hardwaregroup.com Subject: Re: [H] Power Issues Gary, Interesting problem. a) I think that your UPS is too small (in capacity and available wattage) for everything you have plugged into it. I'll assume your ups is the ES350G. It is only capable of 200W (?sustained?). Certainly your PC does not idle at 200W; still, when the printer comes on, the ups may not be able to react to the large load spike of the printer and still supply enough oomph for its' attached devices (PC, speakers, switches). I have noticed that my two oldest PCs that use "last generation" PSU's still record 120W-133W on their Back-Ups 1500LCD on startup. Both PCs typically idle at the 100W-115W level. By contrast, my three C2D machines w/new 600W psus rarely exceed 70W on startup, and, frequently idle in the 30W-40W range. These new "+80" psus are much more efficient to my view. b) Your printer specs at 20W (sleep), 85W (awake), and, 510W (printing). That 510W is ~1/3 of the total available wattage of the duplex outlet (1800W). I'd put the printer on another power outlet (fused line) than the ups for starters....as a test. JMHO. YMMV.
