I cannot tell what scale your image is. The banding I see under a 
magnifying glass when the heads are out of alignment does not look 
like that. Then it is discreet rows of dots forming lines that at a 
distance can be seen as bands. 
At a larger scale I sometimes see these dark areas and I put it down 
to the liquid soaking into the paper and causing it to ripple. I must 
also admit that the dark bands are at right angles to the direction 
of the heads... I have seen it a lot on EEM.
