Re: Continuous Ink system UPDATE

[John Burch <john2004@bga.com>]

Mark,
Most of my info came from Woodrow, who put ink into lengths of tubing and
watched it drain out as air (or vapor) filled the tube. Yet tygon did not
do that. So, I guess we are all still experimenting. I had tried to lower
the tubes but leave the tanks at nozzel height. This made each end high,
but did not stop the leaks. It seemed that as long as the ink was at more
than one height, there would be high and low pressures on the ink and that
would either suck air in or create vapor. 

Maybe we don't have the final answer yet, but I definitly want to try the
tygon tubing. The leaks are so slow and vary so much between colors and
between different installations, that I will have to wait and see if I can
find a solution. It sure sounds like tygon tubing is good insurance and if
changing tubing fixes the problem, then how could it be any thing else but
bad tubing??

We shall see.
