Nearly everytime I print out a noozle check pattern I see clogs in the MK-position (I leave it in all the time cause I figured out (with the kind help of Paul) how to print on glossy and Matte with the dark greys building black for glossy). So even after one or two days the black position does not ive a proper noozle check. Is that normal? Any ideas how i can avoid this?

As I figured out, the missing lines are always in the same place (after about two days 2 lines, after about a week sitting 4-5 missing lines. I think (not quite sure) the problem occured since I put a claria black in for some prints and after that the Eboni again. The last two days I had to run a cleaning cycle before printing to get the K-position clean. The other ink positions are fine. I´m a bit frustrated, because i was so happy to get the system going and get amazing (esp. matte) prints with it. Can I do something with the printhead (cleaning or something like that) to get rid of the problem?
