This paper likely caused a very gently used HP8640 that had occasional paper-feed issues re the ADF but not from paper trays to jam. I will try to avoid Staples-branded papers in the future as I experienced similar issues with a new sheaf of their legal-sized as well.
This paper produces clean professional results that are a step above the cheap 20 lb. papers. I haven't had any problems with jamming in our home printer and I go through a ream every two months or so. It's also fountain pen friendly an added plus!
