Digital BW, The Print

Albert,

This sounds like what is sometimes called corduroy banding where no paper
shows through but the density varies to create bands parallel to the travel
of the print head. There have been times with my two 1280's when this was
not present but for the most part it is there. Various things can help but
never seem to completely eliminate it but I have mine down to where you need
a loupe to see it.

Try cleaning out the heads with Windex or ammonia and water using a syringe
and cleaning the undersides of the heads.

Full head realignment, not just the lines portion but the two rows of
squares as well.

Try sending your file to the printer at a different resolutions. This can be
a big help and will often move or narrow the effected tonal range.
