Maybe it's just this batch I got but on several occasions as I was faxing documents I just printed in the same machine and the printer would drag more than one page through to be faxed. Needless to say I had to stop and do over. Perhaps it was my printer/fax (Canon) or just this batch but I would shake the pages and 'seperate' them and it would work. Other than that it is fine paper. I have been using this paper for a very long time FYI.
I used it for double sided brochures that were tri-folded with folding machine. 20 pound weight edges warped from heat of the laser printer. This caused feeding jams on the second pass thru the printer and handling problems going thru folding machine. Solution: moved up to 24 pound paper and no problems!
