Problem with Overload (constant beeping when printing) on my pro1500

[BillP]

I have two 1500s. one is new. I have a problem with the newer power supply making a continuous beeping when I try making a print on my laser printer. It looks like the load goes over 1000 then starts a solid beep. If I plug the printer into my other 1500, everything prints fine with no load issues. I plugged the old 1500 into the same plug and the print worked fine. It just seems to be the newer 1500 that has this consistent overload problem. Any ideas of how to fix this problem?

My understanding is that you don't want a laser printer attached to a battery backup as they do draw too much power. It is better to attach it to a simple surge protector.
