Travis, I've replied to your tentative solution, which confirms my suspicion that all my problems are due to my model number, 1315xi of the 1310 Series All in Ones, being somehow confused with 1350 !
Don't know if it's my own typo, or machinery, but this happened the day before Sept. 1, and my System Restore closed for previous dates. Created a new "Check Point", but nobody's been able to find any other problem than this one. As I've told you in the post just now,( that I probably can't find again, so I'm also putting this in Tracked discussions) A technician at Driver Update did a remote scan, deleted THOUSANDS of HP bits, so many that Recycle Bin didn't even try to count them as they usually do. I bet you know what to do next, but remember I'm an elderly person and I don't even install drivers myself. Hope it's not complicated. Thanks, Travis. I'll do the Kudo's thing, as usual, if I can find it when I'm just a tiny bit upset. It's been a long day. Thanks so much. .
