Apc surge protector and battery backups

I would replace batteries, they do not have a long life.

1st I see you posted this question in the Printers area. You should not plug printers, particularly Laser Printers, into a UPS. Surge suppressor is fine just not the battery backup. Depending on the age of the APC, you may need to replace the batteries. You may also try turning off the entire unit then pressing the reset and turning it back on.

why don't you replace the battery

I just chatted with Dell support about this since I have the same problem of the grinding noise on my C1760NW Dell printer. I have it plugged into an APC backup battery which acts like surge protector (unless power goes out then battery kicks in). He said the printer needs more power and that surge protectors and battery backups are not good for this printer since they restrict the power which sends less power to the motor and fuser than what it was designed for. So with less power from the APC backup/surge protector, the motor moves very slow and may not fuser the toner to the page correctly and can cause permanent damage over time. So I plugged into the wall directly instead and the grinding noise went away immediately even when printing 10-15 pages right after plugging into wall, but then the noise came back when I printed a bigger job. So for now I'm letting it cool down for a couple hours and crossing my fingers that the damage is not permanent. So... answer is plug it into the wall directly for maximum power and hope that your printer is not permanently damaged. By the well, Dell support chat was awesome.

It is probably a bad battery. They usually don't last much longer than 2-3 years. You could try replacing the battery, but I would suggest just replacing the whole UPS with a new model.

the battery back-up will smooth out the voltage, You will definitely need a battery in or else it will beep nonstop and drive you batty! the APC should have surge protected outlets already built into it. And since you will be using it outside of a computer environment, im guessing on a worksite, there will be nothing extra you need to do besides plugging it in. I would suggest plugging it into a stable voltage for the first hour or so to allow it to charge the battery.

It certainly indictes a problem with the APC unit a replacement bettry may or may not solve the problem. Do you really need one as you have an anti surge protector?

Hi,

Surge protector, minimizes voltage spikes or burst that could damage your electronics. You may not see it doing anything but it does. It clips those voltages to the right rating befrore letting them in to your system.

I hope this helps.

No no need to charge there may loose contact between power cord and surge protecter or internal loose contact between sockets that can be removed

Yes, you must run your phone line thru the BackUPS for it to properly protect telephone equipment!
