No vacuum involved after carts full- but you could get air in the head
and carts. You can remove air from the carts with a syringe and MIS
"bottom fill adapter" using their recovery procedure for a CFS- should
work for a CIS. Even if the ink isn't foamy, it can get out big air
pockets, if by chance it is an issue.

If you were getting good nozzle checks, and if the ink was older than
5 or 6 months, and if you had shaken the bottles up just a tad,
then...
You might want to replace the inkset, it sounds like it may have
problems, though I don't know which ink you're using. This condition
was one of the main symptoms of DSS I discovered with the old Piezo
inkset. At best I could only clear about 90% of the problem by
inserting Epson carts. A couple people had more complete sucess by
injecting Fantastik into the heads. In hindsight, I realized that I
should of replaced the ink at that point, as the DSS only came back
within two months.
Use your own discretion of course, inksets can be $$ to replace. And I
would make sure all three conditions above have been met first.
thus I assumed that the
heads were experiencing some build up.
This was the case with my DSS too, as inserting Epson carts
temporarily cleared 90% of problem.
So I thought the heads needed
cleaning,

What did you use as ink/fluid to perform the cleaning cycles? I
wouldn't reinstall the CIS with the pig ink. I also would not use
cleaning carts. I would only use Epson carts.
So I thought that I would
try cleaning the tubbing and I bought new CIS carts, these are now

Sounds like air in there- Epson carts/purge patterns could clear. Your
pig ink has to be okay too though. You can run just one color purge
pattern full page or all colors-files on MIS site.

Okay, as suggestions, not as a font of absolute wisdom<g>:
Use Epson carts to flush out heads/with purge patterns. If on the off
chance ink is bad as defined above consider replacing (this would also
mean yet another replacement set of CIS carts). If you stay with the
old CIS carts (punctured seal), this may help slightly... inserting a
syringe with a bottom fill adapter into exit port, drawing out ink,
dumping into bottle, repeating, etc- to remove excess air. Be carefull
not to poke any filter/screen that may be near exit port in CIS cart
when using bottom fill adapter, insert gently.
