Print head complaint and other colors

[msenjur]

Hello again

I have replaced print head (left one) few months ago. At that time i was using colors that was not original. Already then there were some problems with black nozzles. they werent ok. The tech said that it is probably becouse of non-original colors, and that eventualy the head should be ok, when i will print some material... Now im using original colors again, and the black still has some missing nozzles, but sometimes it was ok. Now i cant get clean nozzle check! So, i did complaint about print head, becouse it has 3 month warianty, but tech-guy said, that he can't do complain becouse i used other colors. So, do you guys, wich are using other colors know that warianty has no meaning if you use other colors???

I know Roland down here will only warranty the print heads if you are using their inks. All other components which the ink doesn't come into contact with are still covered.

about other componets i understand...

so just like that non-original color can damage print head?

Different inks use different pigments. Cheaper inks use cheaper pigments which I am led to believe are larger or heavier. I guess if the heads are designed for it clogging etc might occur. I am not saying all 3rd party inks are the same but I can't see how we can expect manufacturers to give a blanket policy on the warranty on the heads if we start using inks which won't help them out.

A good 3rd party ink supplier should stand by their product and offer to take over the head warranty if they have confidence in their product.

hm. yes you are right! Studpid me - i didn't ask about that when i was buying other inks!

Did you flush the ink lines, dampers and heads when you switched from "non-original" to "original" inks?

 

[msenjur]

nope. i didnt do that!

On friday the tech guy came, and try to do some ultra-sound cleaning of the head... but he said that there is no warrianty that head will be better. It even can get worse. And than we should buy new head anyway... So we decided not to do this cleaning... Did some of you ever use this kind of cleaning??
