Paper jamming and feeding unevenly

Sounds like an obstruction on the right hand side of the feed mechanism. All-in-ones are a pig to find these - I've had one HP almost completely stripped before I found a chad of plastic stuck in a corner. Nine times out of ten it's a torn corner of the first bit of paper to get chewed jammed in the feed slot.

Check the machine carefully, sometins a small sliver of paper is caught in a critical place in the printer and will give the paper jam message. If you paper is being torn it is most likely due to an uneven feed caused by feed wheels that are slipping on one side while the other side still feeds normally. Clean all the feed wheels in the paper path with a Q tip soaked in Isopropil Alcohol. Also make sure that your paper guides are set to the correct widths.

Remove all print paper from the paper tray. check if there are any dust particles or any other substances that might be jamming the paper. That is the only fix.

Look closely at the "path" that the paper takes through the printer -- you probably have a small piece of paper stuck somewhere, that is causing the paper-feed to get "skewed".

Failing that, take the printer to a qualified technician.

Check the feed rollers, (IF you do a alot of printing), the feed rollers are slick with paper dust, and are causing the jam, You can clean tyhem by taking out the paper, and clean the roller with a cloth rag and some 409 cleaner. scrub the feed roller to remove the paper dust, then let the rollers dry, then re load paper and begin printng

the left side of the printer pulls the paper causing the printer to jam when trying to print

please check print delivery sensor

I have discovered that my problem was a one inch nail which had at some time been dropped into the paper feed slot. It could not be seen from the outside of the printer and was only discovered when I removed the side trim and top cover. When closely inspecting the nylon roller system that feeds the paper out, I saw a tiny piece of metal that looked out of place. Further probing then loosened the nail back to the paper input area.
My printer is now back in full operating condition after spending a couple of careful hours finding out how to remove the trim.
A well worth while exercise in my case.

try cleaning the rollers with alcohol, the tires are probably dirty and one side is not gripping the paper.

Try replacing all paper. Sometimes paper that is overly humid or has gotten wet will curl. Replace with new paper and report results.
