i have a canoscan fs4000 that has served me well over the past 5 years. over
the past few months i have not used it very much and have not had a protective
cover. now my scans have streaks stretching across the whole image. it very
clearly is dust inside the machine (there is dust when i open up the door).
what is the best way to clean this? a canon usa service charge is estimated
at $258. or should i use a vacuum to suck out the dust? or a bottle of the
air spray stuff? or are there other 3d party repair shops to do this?
thanks for your help.
