Is there a danger of that happening with modern toners? 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. Jon
Re: sticky copies and laser prints
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 On Tue, Jun 6, 2017 at 8:33 PM, Pete Turnbull via cctalk < cctalk@classiccmp.org> wrote: > On 06/06/2017 23:58, David Griffith via cctalk wrote: > >> >> Often when I comb through old documentation, I find that the years, heat, >> and pressure appear to have remelted the toner such that pages get stuck >> together.

Is there a danger of that happening with modern toners? 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. paul
