In order for a vacuum cleaner to work you must permit air to move - and
sealing all of the holes except the one that the hose is attached to
prevents any air moving.  You can see this if you tape a glass tube to
the end of the cleaner hose and then try to vacuum some dust from a tray
- - the dust all falls back onto the tray when the tube is pressed against
it to prevent any air getting in.

Even if you managed to get a vacuum pump and take all of the air out of
the scanner, you would still be left with dust in there...  :-(

Even if all but one hole is sealed I doubt if the scanner so air tight as to
create a vacuum. I would guess there would be enough extraneous openings to
create an air flow. Even so, you still could leave one hole open in the
opposite end of the scanner in order to provide an air flow.
