Jochen, and anyone else who wants to chip in here...I hope the following
makes sense and helps in the resolution of this problem.

When I sun scanimage > out.pnm it appears to work at first then issues
the following screen output
Missed a bink: got 3 [0xFF (255) 11111111], wanted 1, waited 700 msec
Missed a bink: got 3 [0xFF (255) 11111111], wanted 0, waited 700 msec
Missed a bink: got 3 [0xFF (255) 11111111], wanted 0, waited 700 msec

I leave it a while longer (minutes) then I couldn't resist lifting the
lid (I know I shouldn't) and see that the lamp is stationary about 1
inch from the home position.  When I break out of the scan (using
CTRL-C) I get the following output
scanimage: stopping scanner...(sig 2)
scanimage: sane_read: Operation was cancelled

I can then reset the scanner by issuing a scanimage --test command.
the output file out.pnm is 9709605 bytes long!  I'm afraid I have no
where to 'publish' it on the web, so write to me separately if you want
me to send it to you.  When I try to load it in gimp I get 'premature
end of file'.

I have just tried scanning as root using gim (and again using xscanimage
on it's own) which obviously invokes xscanimage.  

I have noticed that the Geometry is set as follows;
Top-left x 0cm
Top-left y 0cm
Bottom-right x 21.7cm
Bottom-right y 29.6cm

It appears to make no difference whether I'm root, local, or remote, nor
which device I choose to use (net:linux, net:localhost, or
mustek:1200CP).

The page I'm scanning has a actual left-hand margin of 2.9cms, however
xscanimage reports this as 5.1cms (i.e. the first text appears at the
grid mark equivalent to 5.1cms).

The furthest I get to the right-hand side of the page is approximately
11.5cms (of actual paper, including the left-hand margin), and yet
xscanimage reports this as 21.7cms (according to the grid at the top of
the page).  

In reality I'm missing the last 9-10cms of my page (horizontally).

The top and bottom margins are correct!

Here's the output from the above command run as a normal user (i.e. me)
