Apologies for the late reply - I've moved house and started a new job!

It took a certain amount of cunning to get the scanner apart in such a way
that I didn't cause any permanent damage. I'll tell you what I remember.

There are two plastic strips at each edge of the scanner. One end of each
of these is engaged in a hold to secure it, and the other end is held in a
slightly less secured slot. Essentially, you want to carefully peel up the
middle of each strip (they're glued, but not too strongly) until you can
pull out one end (should be the end nearest the front of the scanner).
When all the glue has been lifted, pivot each strip vertically through 90
degrees about the other slot and it should come out.

Once the strips are removed, the glass will come out fairly easily, but be
careful not to damage the scan head whilst sliding the glass back and

When re-assembling, the glue marks should help you get the glass in the
right place - it has a calibration thing at the scan head end.
