In laser printers running synthetic stocks (polyester based) static electricity builds up due to the image transfer mechanism involving 50KV roughly.
As the sheets come out, the operator can get a spark and they do hurt.

How can build a device to lessen the static electricity on the sheets at output?
My only idea was to have a very fine two sided metal brush at a small angle to the paper, full width, that would **** part of the static electricity as the paper comes out of the machine and brushes itself through this two sided brush. Presuming that this is not a dumb idea, and you don't have a better one, how could we do the electrical setup so that it actually does **** up the static electricity?

If I have the general idea that a certified electrician can follow that'll be good enough to make quite a lot of operators very happy.

Hi,

Usually there are carbon fiber brushes at thd paper output.

Does your printer have a true earth ground connection?

I agree with KlausST. The laser printers that I'm working with have already built-in devices to discharge media surface.
