Yes my experience with this printer includes both Piezo inks and MIS VM. But
incase your question is "is MIS VM prone to greenies or DSS" I don't know,
but I don't think what I am referring to is as drastic as either of those.
My point was I think printers go through periods of subtle variance, which
makes predictability difficult.

I think what I am speaking to is printer inconsistencies that occur without
regard to what ink is in them. I sometimes get this microbanding (would
someone please define microbanding and submicrobanding for me, and what is
the corduroy banding called?) even on my 1270 with Epson inks.

Sorry if I misunderstood where you were coming from.
