There's no real difference between 9000, 9500, 7000, 7500, 5000 
heads. The ordering numbers for the 9500 are different and they 
probably are different for the 7500. There's more to it as 
described here by K.T.Chan:

 >>The f055070 is 6 number and alphabat coded.
The f055030 is 5 number coded.
I use the 030 for 3000 and Mutoh.
The o7o, o8o o5o can be in the 5000, 7000, 9000, and 7500, 9500.
with the service program the 070 can be converted to 5 number 
code and be
used in 5000.

Price of 070 is 10 % higher in HK.

Red dots on dampers and heads indicate that they have had a 
better testing on flow and banding resp.

The only other problem seems to be that they deliver refurbished 
heads nowaday in the US. Check that you get new ones or get new 
ones that are meant for another printer but usable on the 7000. 
One buyer complained that the refurbished ones are just bad. I 
find it hard to believe that heads are refurbished but nevertheless.
