HP Designjet T520 failure

[JoachimOvrid]

Hi.
We have HP Designjet T520 product number: CQ893A and serial: CN65D7M034.

Error message:
There is a problem with the printer or ink system. Turn printer off, then on. If problem persists, contact HP".

We earlier had some problems with ink leakage. 
When I am removing the black ink container, the error message disappears.  Tried to install a brand new black ink cointainer, still the same error message. 
In HP Design Utility software on the pc it says a orange warning signal with "!" on the brand new black ink container. 
How to fix if the problem are just on the black ink?

We tried to insert one ink at a time, still the same error. 
We verified it is the correct ink that are in use.
We ordered a new printerhead. What else can be wrong? What other parts maybe should be changed? How to fix?

Where can I get HP technican to have a look at it? We are in Stavanger in Norway.
How can we hard reset the printer?
How can we get rid of the error message?
