It's shenanigans like this that make me never want to buy a Canon or HP product. If I need a high end inkjet for printing photographs, it's Epson all day. For anything else, I swear by a good used bulletproof Brother.
Brother was good but I’m disappointed by the last units I had. After 4 years of light home usage (one page here and there), they are not picking up paper in the tray. Same for some relatives which bought similar units. Feels like scheduled obsolescence …
If it's just that, then the rubber on the rollers had probably dried out. I had the same issue with a 10 year old HP inkjet. Some mg chemicals "rubber renue" worked great.
I had this same paper issue! I solved it by using heavier weight paper. I think it's just wear making parts looser. I think it just sincerely can't grab the cheap, thin sheets as well as it used to. If I were more mechanically minded, I'd be tempted to get in there and see if there was anything I could adjust. But just using heavier paper solved it, so I haven't gotten to the "if it doesn't work, force it; if it breaks, it needed replacing anyway" stage.
