Digital BW, The Print

Hi fellow listers;

I have been using MIS UT2 inks in my Epson 1280 for a while and love 
the prints I can make with these inks, however I am having one MAJOR 
problem in using the inks in MIS loaded cartridges.

I have noticed that when I go to install a new cartridge and peel the 
tape off of the vent holes, I get a very noticeable sucking sound ( a 
lot more than with OEM carts ). I also notice ink that has been sucked 
up out of the vent holes. I think this is creating lots of air / 
bubbles inside the cartridge chambers. I then get many BAD nozzle 
checks. Since air bubbles are causing the problem rather than clogs, 
cleaning cycles do not help. The only solution I have been able to find 
is to wait 1-3 days  for the bubbles to dissipate and then I get a good 
nozzle check. But waiting severals days every time I need to change a 
cartridge is not a really good option. Sometime you just want to make a 
print! I don't want to go with a CIS because I sometimes go for long 
periods without printing.

Is anyone else having this problem? Is MIS doing something wrong on 
their end with the filling process to cause this problem?

On a more positive note... once I do get a good nozzle check I have no 
further problems. I have left my printer idle for 3 weeks. When turing 
it back on after this prolonged period I almost always get a good 
nozzle check.

Thanks in advance for your thoughts!
