All these, printers, plus larger dot printers like the 3000, use the same 
dithering resolution of 720 x 1440. So, as the dots get smaller, the space 
between them gets larger, and actually blending the dots on many tones 
ceases, causing the visible (or magnifiable) bands. Improved dithering 
patterns helps with this, but as you point out, it is clearly visible in 
magnified prints, on many papers. Printhead problems can increase this 
problem to the point it becomes visible to the naked eye.
