Re: Epson 1650

I can't answer for the Epson 1650 specifically, but I don't see how 
it would be any different from any other scanner for which my generic 
answer would be:

o I personally have never had a problem that I could attribute to 
leaving scanners (or computers or printers or hard drives, etc.) on 
for weeks at a time.

o I have worked at several computer and software companies where 
hundreds of employees left everything on continuously and I've never 
heard any hint of excessive equipment failures.

o It's true that the flourescent tubes in flatbed scanners have a 
limited operating lifetime (in the 5,000 hour range?), but they 
normally turn off after a period of inactivity to prolong this.  So 
leaving scanners on should not noticeably shorten their lives.

o I've heard a rumor (but not tested myself) that you get less 
scanner induced shadow noise when the scanner's only been on a few 
minutes; before the CCDs have been warmed by the adjacent electronics.

o The only caveat I can think of is that if you have frequent, large 
power spikes then turning off your equipment will help protect it 
from spike-induced failures or shortened lifetimes.  Similarly, if 
there's active lightning in your area unplugging your equipment is 
often recommended.
