It was me who wrote the report originally. I removed only the lamp carrier (2 screws) and the front upper portion of the film advance housing (4 screws), then decided any further dismantling looked too hard and probably unnecessary. Access to the reflex mirror is limited, through a roughly 20mm x 15mm aperture in the bed of the film carrier, but I found it was enough to be able to thoroughly clean the mirror with a DSLR sensor cleaning pad on an angled arm (I use Green Clean, the wet pads have a plastic arm, and I heated and bent one about 45 deg). My mirror had been utterly filthy with thick dust. Once I'd done that I could shine a torch onto the mirror and was able to see the lens cell reflected. That was perfectly clean, so I left it alone. Just as well, getting to it would require an awful lot more dismantling. The only other thing I did was to wipe the parts of the coarse and fine carrier advance worm gears and support rods that I could see, using a pad with some WD40 to remove old lubricant. I then dribbled a little light machine oil onto the rods and some light grease onto the worm gears. As expected, after reassembly, the carrier movement distributed this to the areas I couldn't get to just by scanning a few frames. The sound of the mechanism changed noticeably, sounding less strained, during the first couple of scans. All the internal dust I could get at was removed at the same time, especially the little sensor notch toward the rear, LHS of the carrier mechanism. I have no idea how this sensor works - it doesn't even look like a sensor just a V-shaped notch in plastic - but that is what detects the filmstrip holder is not the mounted slide holder. Mine was filled with fluff that wanted to stay there. You can figure out where it is from the design of the Polaroid brush (which I don't have). Just cleaning that mirror has made an amazing difference to scan quality. It also now very seldom fails to correctly recognise the filmstrip holder at the first attempt. I think I've had 2 misfeeds in maybe 30 loads. It had been driving me crazy before, misfeeding about 2/3 the time. > Any suggestions? Is there a site with some images of this process?
