My experience with Piezo on a 1200 was that I was always getting sub-
micro banding in the 25 - 50% tones in very smooth sections of the
prints. These sometimes got bad enough to be micro banding.

With MIS VM on a 1280 I have fine corduroy banding in the 50%-80%
tones that can only be seen with magnification.

Are you using a Cone Piezography driver on both printers?

I have used Piezography inks with both the Cone Piezography driver and
Epson's driver. With the Cone driver driver it is virtually impossible to
avoid some form of artifact somewhere in the grayscale, usually only visible
in smooth toned areas. It takes several forms including banding and
patterning. The problem is that the Cone driver requires perfecty printhead
alignment in all axes. Most of us cannot achieve that. I find the Epson
driver more forgiving and therefore prefer it.
