I primarily use this product for work printing and making copies. As I am trying to fax and/scan it sometimes jams (meaning it does not feed through the printer without guidance. Not sure if paper or my machine (in which I bought at Staples about 6yrs ago).
I go through about a case of legal and a case of letter a month and bout Hammermill letter this time with Staples legal. The Staples brand is a much better quality paper for the price!
