You don't need a hardware realignment on the 7000 like you need 
one on the 9000 ?  With the service manual at hand you  use the 
service mode alignment tests to set the height of the light ink 
head to the height of the dark inks head (that's the right 
lever's task) after that the slant of both heads is corrected 
with the front levers (first the left one, the right order of 
handling may be different but that's written in the SM).  I 
replaced the Phillips screws in the middle of the heads with 
Inbus (US term is different, hexagon hole in the middle) screws 
as you often have to loosen and fasten them in aligning and the 
Phillips screws require too much pressure on the head carriage to 
turn them. !!!! Metric thread however !!!!
After that you have the software alignment. So describing at 
which point the levers should be is in my opinion not done :-)
The heads don't shift easy with the levers (clumsy design, 
plastic isn't stiff enough for levers, heads stick to the plate 
they move on) so a small screw driver as a lever to get them in 
motion isn't a luxury.

9000 knowledge, never done a 7000.
