I have replaced the batteries in the two that were beeping but they are still beeping!!! I have been searching on here and have found clean the detector, replace battery, replace back up battery. Any idea of why they would beep only after a power outage? Thank you in advance.

The rollers on Deskjets need to be cleaned from time to time. It is jamming because it cannot pick up the paper. Get some long q tips and some alcohol and clean the rubber rollers. Also, go to the HP website, support page. download the latest printer driver. They also have a Q A page that you can get more answers there. Hope this helps.
