Mark,

While I was doing some testing with hand loaded carts. I pulled the CIS
carts out and set them on the printer with the lid open just above the point
where the CIS arm ends. I plugged the bottom cart holes with the rivets from
MIS. All the ink ran out of the tubing and back into the bottles. After
about 10 days I changed the black CIS cart using a vacuum fill and installed
it along with the old color cart. As I started doing nozzle checks,
cleanings and purge prints ink was pulled back up out of the bottles and
into the color cart. Basically the pumping action of the heads is enough to
suck ink out of the bottles or the CIS wouldn't work.

When you flushed the ports with Windex did you just push the Windex through?
When I did this I also pulled the syringe back putting suction on the ports
to pull any debris out to the nozzles. You might try this again. Push Windex
through until everything is coming out clean on the paper towel underneath.
Then let the Windex stand in the nozzles for several hours and then suction
it out to get out any chunks that may be too large to go out the other side.
If this back flush is not clean you might want to repeat it.

Did you try running some Epson carts?
