Jim,

I have observed the drying out or pigment depositing in the lines. When I
decommissioned my 1200 NoMoreCarts CIS after 14 months to reuse parts for
one on my 1280's I found very heavy build up in the lines. Worst was the
black of course with some in the gray lines as well. Nothing in the Y line.
As we have discussed before it would be prudent to replace the CIS
cartridges and clean the lines and bottles on a regular basis. The frequency
I am not sure of. At least once a year perhaps. Maybe every 6 months. It may
depend upon usage and local conditions.

Yes, Martin and this has me worried, esp as I am having to do more 
cleanings to get the nozzle clear every 12 hours when I turn it on. I 
am hoping that it is due merely to not being able to yet keep the 
temperature down to 68-72 degrees f in the room (air conditioner 
doesn't turn on with outside temp below 65 degrees). I seem to be able 
to hold the RH at above 40% and it still has trouble now.

The worst thing is that the deposits visible in the bottle seem 
lately to be increasing on probably a non-linear basis- and I have 
only had the CFS in operation for 1 1/2 months. As yet I don't notice 
anything in the tubing but this is harder to detect and anyway, the 
line is getting new ink in it every 12 hours. It shows up in the 
bottle.

Our situations are probably different, as you know it is a dry climate 
here, perhaps even using an humidifier will not cut it for me. 
Replacement of the CFS every month or two is obviously not a viable 
solution. I was hoping for at least five months. We shall see. I think 
tossing the CFS/ remaining ink after some number of months is 
mandatory for some.
