I hadn't considered the possibility that my "clogs" would be air bubbles, but next time I get one I'll look into it. If so, they would probably dissipate after shutting the printer down overnight instead of immediately going through one or more $5.14 head cleaning cycles, which is what I estimate each one costs.
Your CIS must use some pretty Epson-compatible ink. From what I see and hear, the primary cause of clogging in these Epson pigment ink printers is use of third party inks. That was what I think the reason for all my trouble with the R800 was, which I was finally able to correct with extreme measures a couple of years ago, and it's still chugging along nicely, with only Epson inks, of course.This reviewer
so far seems to think the R1900 is a considerable improvement over the R1800 except for one thing, he thinks the ink cartridges are too small.
Epson is the primary promoter of the notion that only their inks are any good. The marketing term for this is "FUD" for Fear, Uncertainty and Doubt.
I did a long evaluation of this before I switched. You can read about this on my blog here:
Where I talk about my experiences with my R1800, Mediastreet inks and my Mediastreet CIS. In a nutshell, what I found is that the longevity of the mediastreet inks are just as good (if not better - both exceed the longevity of silver based chemistries and dye inks by spectacular amounts), I get better results that I got with OEM inks and papers, and I'm saving something like 70% of the ink cost.
The issue is if you select crap inks, you will have problems. If you chase the OEM ink in our printer with an ink that is chemically incompatible with the OEM ink without flushing you will have problems with clogging. If you select high quality inks, get custom profiles (no big deal), and understand your color flow it is very straightforward to get results at least as good as the OEM inks and probably better while saving an amazing amount of money. For example, I have save enough money to buy a new printer every in the equivalent amount of ink in 8 cartridge sets.
That said, the results from the R1800 are so good, that while I'm sure the R1900 is better it isn't going to be "oh wow" better. Even if it is, it will only be a short while before the 3rd party guys have an ink set to match it, I'm sure.
