anybody here know how to clean the dust from the inside of a plustec 7200 film scanner. I haven't used mine for a while and it has huge amounts of dust. Must be on the sensor but I cant figure out how to get inside the little bugger to clean it. I can get a lot of screws out but nothing moves. I just cant get inside that darn case. I'm sure there is a trick to it. Also what is the best way to clean the whatever it is that collects dust inside there. I hope there is a cover on the sensor but I wouldn't bet on it. if none of that is possible who do you reckon could clean if for me.
