When they took the Rizo Machine out of our school there was no copier that would run construction paper. I found that the heavier quality of copy paper was a good replacement.
The quality of this paper is superior to the others available yet it was the least expensive! I use this for double-sided copies and the color & text didn't bleed through to the other side.
Jams sometimes but less if fed on reverse side. I produce double sided documents and had to give this more attention than usual. It's still a good value at [$] per ream for 28lb paper.
