We get and send a lot of faxes every day as well as making copies etc. We/I have had no problem with this paper- it isn't flimsy and doesn't jam the fax or copier.
We use this paper in our printer/copier/fax multi-machine and it doesn't jam not even with double-sided (duplex) printing & copying. Our office only uses this paper and it is a very good value especially by the case which is how we usually buy it. [...]
