I bought a ream of Double A branded paper since I ran out of these. They were thicker and more expensive tha these. BAD mistake. I kept getting jams after jams on my Brother MFC laser printer. I tried fanning them multiple times and they continued to jam. Went back to these and they printed right straight out of the box. No issues. No drama. It just worked. Buy these. They are cheap and Amazon can get them to your doorstep ASAP.
