Yes.  If stored at high temperatures, like a garage in 
summer, the toner will slowly melt and fuse the pages.
Also, the plasticizer in vinyl notebook binders diffuses 
through the pages causing the same effect, at least a dozen 
pages in.  If the pages are printed only on one side, it 
isn't that bad, if printed both sides it makes a real mess 
of the printed image.

I would bet that there is a "best way" to open a stuck page, but I usually
open very slowly to reduce damage.  It's bad enough we have to worry about
the machines, the disks, the batteries, the caps, the

Yes.  Toner composition hasn't changed much.  BTW, the worst culprit is 
the plasticiser in PVC ring binders.  All mine have at least one sheet 
of acetate (most OHP (viewgraph) transparency sheets work) in front of 
the first page, and behind the last page, which helps prevent the problem.

I would think so.  The underlying technology is unchanged as far as I know.  
It's still plastic dust that's placed in patterns by electrostatic charges and 
melted onto the paper.
