Jack, We also make large products and I insist on ESD testing every place an operator or maintainer can get to. I test in 2kV increments to 16 kV. There are even times when I will go beyond that, like testing the media path (we move polyester film around) to see what happens or to solve specific problems. Tedious, maybe. But cost effective in the long run.

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). Jack Cook EMC Engineer, Xerox Corp.

I consider this just a tad egregious - don't you? Thank you Charles Grasso Advisory Engineer StorageTek 2270Sth 88th Street Louisville CO 80027 M/S 4247.
