Jack,
I also remember instances of a charge being developed internally from the
movement of paper along the "paper-path" of the copier. At that time I
utilized internal ESD discharges.

Charles,
This is a contentious subject for us due to the time it
takes to thoroughly
test a large product, so I'd be interested in hearing
other's opinions and
practices.
A scenario where ESD can cause a genuine problem (in our
business) is when
someone walks across a room to add paper to a printer tray.
In some
machines, the unit will be in standby mode. In others, it
may continue
printing from a different tray or cabinet. In either case,
a discharge to
the internal metal parts of the paper tray could conceivably
cause problems
we would consider failures (and have).

Hello,
Does anyone in this august group apply ESD discharges
INTERNAL
to a product as required by EN55024.
I consider this just a tad egregious - don't you?
Thank you
