As a result of your comment regarding the newer Durabrite Ultra inks, I
did a very brief analysis of the requests for my Epson Cleaning Manual
to see how those printers are doing.
Of course, they are newer (last 18 months or so) which skews the results
since the printers tend to developing clogging problems over time.
However, the results are still looking good. The printers and
all-in-ones which use the Durabrite Ultra inks have a much lower
clogging issue relative to those using Durabrite inks, based upon the
requests for help with clogs.
What this leaves me wondering is this: are there are good reasons why
Durabrite Ultra inks can't be used in printers originally released with
regular Durabrite inks? If not, why would Epson offer the Durabrite
Ultra inks for the older printers? I suppose it is possible the inks
are not compatible with one another and so the mixing could be a
problem, but they seem to have similar formulations (both types use
10-20% glycerols and the same pH). Perhaps coloring is somewhat
different, or some other concern. I don't know.
Based upon this admittedly sloppy science, it does look like the
Durabrite Ultra inks have a much lower complaint rate regarding head
clogging.
