With the electrostatic printing process of course you have static in the paper after printing. When processing thru a folder say 80# text the static buildup is horendous. Has anyone found a way around it?

I sometimes use dryer sheets (the ones for static cling)... tape one to the feed somewhere so it brushes against each sheet as it goes through. Depending on the type of folder it may be easy to tape a few of these on throughout the paper path. Also I spray the folder with anti-static spray each time I load paper or when it's convenient. Still doesn't eliminate the problem but it helps.

*edit*
There's also static string and that copper "garland" stuff that's used for static. I've used it a lot in the past when printing on poly with a digital duplicator.

Our bindery guys hate digital. Toner uglies up the cutter blade, and the static is a joy.
They don't know the half of it.

We print on a 4mil re-positionable vinyl label for one client - they use them as 'clings' on windows and glass doors at convenience stores. You can't wind them and jog them up - not possible. Dryer sheets, tinsel, spray, it doesn't matter what we've tried. We have to peel them apart sheet by sheet and align them up perfectly by hand just to be trimmed. If we ever sent them to the bindery without doing that, all hell would break loose. There aren't enough tissues in the world for all the crying...

If paper sticking is causing alot of problems. I would check your humidity in the air. Too low of humidity will cause paper or plastic to stick. You should be in the 40-50% range.

We are a couple miles from the ocean and normally we will have no problems with static. Then we will get dry winds from the desert and the static issues are horrible. And the fact it gets warm and we turn on the A/C and that makes I even more dryer.

For large rooms the best way, and fairly cheap way, is with 20" fans with high pressure mist nozzles. You can hook it to a humidity sensor that will turn the fan on and off as needed to keep a steady level.
