I had the same problem. Drove me mad for days. Banding at every print head pass, most clearly visible in monochrome or duotone prints, in the middle grays - and worse at the bottom of the (portrait) print (the part that came out of the printer last.
I don't know how much ink I've spilled in nozzle cleaning, head realigning and whatnot. When I couldn't get it to go away, I took a last desperate measure - I upgraded to the latest driver (4-4-2007).
And hey presto - banding gone completely! plus a slight, but at normal vieing distance (holding an A5 print at arm's length) detectable increase in print sharpness.
Your mileage may vary, but I'm a happy printer.
