[filmscanners] Sprintscan 4000 cleaning

["HPA" <tom@historicphotoarchive.com>]

By request, here is a re-post of how I accessed the mirror for cleaning
without dismantling the works.  I did remove the top cover, which pops off
after four catches on the bottom are sprung open.

The mirror of course hinges while scanning, so I turned on the scanner power
(with the lid removed), and pressed the power button, which sends it through
a cycle.  As soon as the mirror was fully exposed, i unplugged the power
cord.  This is when I was able to best get at the mirror with the compressor
hose.

Additional note: I did not have the problem with blowing dust from the
mirror to the lens, I was able to clean both from my vantage point.  I did
notice a huge difference in scan quality.  My unit was about six months old
new out of the box when I did this.
