Z2100 what's wrong with this printhead?

Dear all,

please have a look at this test chart that my Z2100 prints out after the head cleaning procedure:

I run the procedure 3 times in a row, yet light magenta comes almost identical as light cyan. So far so good, I ordered 3 new heads (all but M-Y).

What is a mystery to me though, is how the color of the defective LM head is so much blue and not red at all. I would expect any degree of banding or no color at all, but why such a regular bluish color? Almost like LC.
So I removed the LM LC head and cleaned it with alcohol. Not surprisingly both color strips have been identically cyan.

Yes, sure there is LC ink in the LC slot.

Thanks for your input,
