Jim,
You were kind enough to help me when I had air/clogs in the lines of a CIS.  
Took the CIS off and used carts for printing a show with relative few clogs 
before printing.  I am about to be out of the printing business on this 
machine for about 3 months.  From what you are saying it would seem to be a 
good idea to take the Piezotone carts out and put in Epson carts.  Or is it 
just the path that the CIS has to take that is more prone to clogs?  Also, I 
think I have read that with the new Piezotone inks you DO NEED to use flush 
carts because of compatibility issues with the Epson inks.  Has anyone else 
read this or  know it I need to do this or not.  Can I go Piezotone to Epson 
or do I need to go Piezotone/flush/Epson?

Billie

For three months I think I would even take a dye-based ink out and put 
Epson carts in. Then I would get a friend to at least turn it on once 
every two weeks or one week maybe. Epson inks slide through the head 
like butter, far less clogs- but they still do occur and if it was me 
I still wouldn't let it sit idle for over a week or two.

I don't know about that. Since the cart is always full, it may work 
even better than regular carts, which decrease pressure head with ink 
level, but I really don't think anyone knows for sure. The big problem 
would be evaporation through the tubing or air getting in the bottom 
of the CIS cart, or so I would imagine. I've had both good and bad 
luck with vacuum filled carts and CIS/CFS. It seemed to depend more on 
the climate than any thing else. And moreso on how long I left printer 
idle between prints, even a quickie draft print keeps the nozzles more 
behaved than not printing, for me anyway.

I don't have knowledge enough of the new Piezotones so someone else 
will have to answer that.

Jim,

Glue for the tubing?  Where is the glue used? my cartridges tubes are
just pushed on.
If you tried to glue them on, surely you would get some glue inside the tubes?

Or were you talking about the little black elbow joints that go on the cartridge?

 Just a wild thought, but with the CFS of course, you can buy

Yes I meant for the elbows, which connects to both the tubing and 
carts. Glue is put on interface between elbow/cart. Not on 
tubing/elbow interface.

Thanks for the input. The part about ink going bad has me 
thinking. The CFS system I intalled was new, but the ink was 
sitting for about 6 months, never opened. Perhaps that is 
causing my drying in the lines. After my next round of printing I'll 
install new ink and see if that helps. I tend to print in batches, not 
everyday. Sitting for a week or two is common.
