Quote from Chris: "Once the cover was loose I simply unplugged the small ribbon cable that attaches to the front controls. I used the cleaning procedure as described on your web-site [Canon8400F] (thanks again for this). I did not dig any deeper than cleaning the haze off the platen as I was not sure where any mirrors were located. I might tackle that aspect in the future if needed. Perhaps I should not have, but dishwashing soap (Dawn) did not remove the haze very well so I did end up using blue Windex. I can't discern any adverse effects on the window. There is still a trace of haze left, but it is much better than it was. Re-assembly was simply the reverse of the above." I recommend using Isopropyl Alcohol for cleaning the glass instead of Windex.
