After I have printed so many prints in such a short time I need to do some
cleaning and other maintenance stuff with my printer. I need to established
"SIPHON BREAK" which i lost while using so much black ink. As I had trouble
to see ink going to cartridge through pipe, I used all of it in cartridge
and therefore lost black color completely. I was doing all the tricks and
nothing helps. I was desperate and I am still not sure if I will recover
completely my CFS with MIS inks. Now I have original color cartridges in
the printer and seems that I have got all inks back. I am leaving my
printer to sit for few hours before I put back my CFS with MIS UT2 inks. I
hope I will have my complete printing solution back Monday latest. I must
say this was not nice experience, but all I did it myself. I need to be
more careful next time.
