I use an HP scanner to scan prints and some 35 film stock. I get dust
marks on the scanned files. I know the glass plate is clean (top and
bottom sides) and also the scanned image. The dust must be in the
optical train of the scanner somewhere. This cannot be in too many
places because the dust is mostly in focus. I have had the scanner to
pieces and cleaned it as far as possible but with little improvement. I
know it must be the scanner because if I move the print on the glass,
the dust stays in the same position but the image has moved. Frustrating
but Photoshop does remove most quite easily.

I see dust all the time on scans of negatives I know to be clean, when
scanning on my Epson 2450. Usually only observable on full resolution
scans, viewed 1:1 on the monitor. When the image is "dithered"
down, for emailing or putton on web sites, or printing, the specs are
usually not evident.
The scanner may be causing what appears to be white "grains", which is
probably tiny dust specs on the scanning bed, however, I see some light
"swirling" areas, on the pic, and I don't know what that is.
I sometimes see what I would call white "splotches", lately, when I
stand develop 4x5 film. I am thinking it might be to the minimal
agitation I use in this method, as I don't get the white splotches when
I roll my negatives in a Jobo drum.
