Well try some 5-6 spoons of boiling water & keep the cartridge in it .i men the ink nozzle side in the water for some hrs.
or else,u can try like here.May dip the ink in isoproply alcohol.I read it on cruisersforums

tried isopropylic alcohool but i didnt put the cartidge in it... not successfull ...
the only method that worked about 90% is boiling water....
put the head only in boiling water and then wipe few times in one direction.
Just to know..

Suckers werent successful

Today i successfuly refilled this cartidge!!! I did the mistake to let it dry for several months...
Unluckily i dont have a sucker and this is a problem..

After refilling i couldnt see anything at nozzle check(almost)
THen several eforts with windex helped but a little..
I let the cartidge in windex for 3-4 hours...
Then i used our steam cleaner and spayed with steam the cartidge for about 1 minute!

Then i repeated that but no success initially.. After removing the water thant had entered the cartidge i got great success!
Black cartidge which had several invisible nozzles and many dull no all dulls were clean and only one nozzle had problem..
ALso the 344 was almost perfect!
