Regular copy paper is all I use as well.
Just checked and mine is a 20 lb. paper.
Like the others said, shorten your stitch length down ... I go down to 1.0 !!
Never any problems, to remove the paper, even if multiple seams come together.
Just be sure that any seam edges that are going to get buried, that you remove the edge before the next seam is made.
I keep a roll of painter's tape handy for band aids, just in case any of the paper falls off too early!!
It's iron friendly, whereas scotch tape will melt and create a real mess!
