A production laser printer will be wadding up paper long before the
electronics start complaining. If the paper is too wet it will curl

at 3 pages a second will turn the stacker into something that looks
like a carnation.

That may be true, but it doesn't mean it's only the printers and
card readers that are in controlled environments.

I think people are far too concerned with the rest of the electronics.
DASD in a data cernter is just the same drives you have in your PC
piled in a big box these days and the processors are not that much
different than your PC. It is certainly a similar packaging. I have
PCs running in totally unconditioned space in SW Florida with no
problems. In fact one survived a fire. 3 are running in vehicles that
see 130-140F in the day time and wide swings in RH.
IBM started saying in the 80s that if the people could handle the
environment the computer could. 4300 mainframes and AS/400 mid range
were "office environment" machines. It was really the big paper
pushers that needed conditioned space.

Mainframes are *not* specified for office environment (rather
"Class A") though. There is a difference between a "departmental
server" and a data center mainframe.
