Digital BW, The Print

Hello Tomek,

I'm still waiting for MIS to make available the
new cartridge design for my printers, but I feel I
must share with you what I know about them.

After reading at the MIS site on the new
cartridge's inner workings, I proceeded to make a
simulation to test out the design. I found that
the initial ink spill is inevitable but will
disappear after a certain amount of printing,
unless the cartridge is primed after refilling
using a bottom fill adapter.

After refilling, there is positive pressure inside
the cartridge. This pressure is relieved either
after some printing or through priming.

About clogging that consistently appears after
some printing, the only explanation that I have is
this thing is called "ink starvation". Why you're
having ink starvation, I do not know.

(Pigment) ink buildup in printhead chambers, and
UT2 maybe a little heavier than what you used to
use? Cartridge has abnormally restrictive air
vent?

Jim who started the "A year of pigment printing -
1280 clogging" thread reported great success using
the MIS flushing liquid.

Good luck,
--nick
