I purchased a Fujitsu 5750c scanner off lease, but unfortunately the ADF
colour scans have stripes in them, which is going to be a sign of
internal dirt, or if I'm unlucky, bad pixels. Fujitsu itself will
clean it, but at a cost of about $500(!). That makes sense if you buy
one of these new for $4,000 but not if you get a used one off-lease for
$1800 on eBay. Nor does their $1000 service contract make sense.

So, anybody have advice on how to find a technician who has experience
in opening one of these up to clean it, or on how to clean it myself if
need be?

These are _heavy_ suckers, about 85lbs, so they are not easy to ship.
I thought since Fujitsu is just 2 miles from me in silicon valley that
might make it easier, but it does not.

This technician could do this. And the cost would be about the same.
The advantage of having Fulitsu do this is they have the necessary
documentation, experience, tools, equipment etc to do it. And probably
with a warranty. And then you would have your scanner for $2300.00
instead of $1800.00.

Just a guess but your problem is probably some particles of dirt, or
the equivalent, in the optical path between the light source and the
scanner sensor. Perhaps trapped by a narrow strip of glass thatseves
as a lens in the optical path. Open a few covers and have a look.

Do you have the service manual?
