Microtek Artixscan 120TF needs a cleaning - how????

[Tom H.]

I am in the middle of scanning a bunch of X-Pan transparencies, and noticed a ton of dust not on the film.
This unit does not have ICE, so it's an hour cleaing up in Photoshop.
Wondering if anyone has had any expereince (or know someone who has) taking this unit apart and cleaning the CCD with a proper brush.
I've looked on line and not a word anywhere - thought there is for the Nikon 8000.
Any help much appreciated.
