I'll put this together bit by bit as I switch back and forth from the site, so forgive any disjointedness...
1) Nice colour scheme (I like that blue generally, and it fits with the company type)
2) There are at least four different 'types' of rollover behaviour on the site: on the first page - the left side links, the drop down menu, and the right hand side; on the subpages, the "home" rollover.
It makes it seem a little bitty and disjointed for my liking.
With the menu divided between left, top, and right, it wasn't clear to me how the menus were related
3) The left menu (large document, etc) - I'd personally make it so that pointing to the round bullets also acts as the link, and triggers the image swap. Just a personal thing, but it didn't feel right that the screw-heads(?) didn't "do" anything...
4) The top drop down menu - odd things seem to happen with resizing the page: menu being truncated, not disappearing properly, not being in the right place, that kind of thing (IE 5.5, windows). Also it isn't clear which items are direct links, and which items trigger submenus, particularly when the submenus don't always disappear when they should - you'll need to check the consistency of the layer appear/disappear behaviours there.
5) The right menu: first item (levels/lasers) seems very squashed in that box, as well as having a strong black border which none of the others have. Also when the image swap occurs, the segments slide sideways - and become rectangular, rather than looking like the same shapes moved across. Is it supposed to give the appearance of a sliding block, or am I just misinterpreting the model there?..
6) I expected the three items at the bottom - quality, service, experience - to be clickable...
7) On some subpages the left menu (large document copying, etc, etc) disappears, on some it is retained.
All in all, not too bad, but comes across as very inconsistent. I'd strongly recommend picking one of the navigation systems and sticking with it for all the navigation, or make the navigation systems less dramatically different to each other.
