One lesson we might draw from the years of weeping
here about clogged 2200 is to avoid 3rd party ink in
2200.

Easily 90% of the tears involve 3rd party inks. 

(someone happy with non-OEM usually jumps in to blame 
users rather than ink, but I generously attribute
their reports of success to luck).

Another observation is that reports of clogging seem
to be increasing. Perhaps more people are using 3rd
party inks, or perhaps 2200's are dying of old age.

Having seen lots of examples of MIS/Piezo/OEM, QTR
with OEM looks as good as alternatives anyway. MIS and
Piezotone may produce faintly measurably better blacks
on some papers, but OEM still reportedly does better
on others, and the papers are changing.

Some measurement reports seem dubious, some measuring
folks seem constantly to be changing papers ( their
love may be tinkering more than photography, and this
is a printing Group, not a photo group after all). 

My own reluctant decision is to give my mortally
clogged non-OEM 2200 a viking funeral and to continue
to love my OEM 2200 until something better than 2400
comes along (it sounds like 1800 is an Edsel).
