Hi, does anyone reuse printer paper? I try but it seems to lead to more paper jams. Any suggestions?

The rough edge of the paper needs to go toward the rollers in the printer. 

Not ever in the machine. Increases the risk of damage. Paper is cheap, printer is not. Best to just use the paper for scratch.

Paper is too cheap to wreck your printer over it (and yes you can). Just set it aside for scrap and use a fresh piece. Some printers are better designed to do the double sided copy, but they tend to be at a higher price point.  My brother paid extra to get a decent Canon printer that does both sides nicely. It was a feature he wanted but has only used about 12 times since he bought the printer 2 years ago so a waste IMHO.

The older style inkjet printers were fairly fine for reusing paper (as long as NO wrinkles or bending or folds)--where the paper was open in a tray below and you see it sucked in and start to come out the top.    That's a simple paper path.

Ones that have fancier paper paths (anything with a paper tray that slides in, lasers, etc) are a lot more likely to jam.  They are just more touchy and I can't recommend trying it.  If you are going to do it--use the manual feed tray.  Unfortunately, that's less durable than the slide-in-paper tray, so it'll wear out faster.

Just found this forum.  Hope you all don't jinx me.  I have reused paper forever.  I always make sure the edge going in is perfect.  No folds, no bunches nothing wrong.  I have had jams using new paper out of a new pack.  It's how one removes the jam that matters (my opinion).

I have a nice Canon.  Quit my HP.  Too many ink carts.

I use the back, blank side of paper all the time in my HP Laserjet P1102w. Even use junk snail-mail with ad sheets printed on only one side. The only time I've ever had a problem with a printer jamming is when I stupidly add a bunch of paper to the tray and overlook two sheets stapled together.
