VS-540 Yellow banding issue

[BrianX]

I am having an issue with my VS-540. Yellow, and any color with yellow in it is banding really bad. I have run medium and powerful cleaning several times, done manual cleaning, adjusted bi-di and calibration.
In the attached example photo, you can see that the banding is not occuring in any of the blues or purples, only yellows. In the test print, there is one line in the yellow that appears to be blue.
Any suggestions would be appreciated.

whats up with the black channel in the far left of the nozzle test scan?

 

[woolly]

That looks like the capping station is blocked why not 8 colours
Giving cross colour contamination
Happened on my vs but with the white if under warranties give them a ring

That is the silver metallic channel. It is always spotty until I print something in metallic.

Looks like it was a bad capping station. One of the hoses for the waste ink was completely clogged, which fouled the capping station and caused cross-contamination. Replaced it with fuel line for model airplanes - back up and running.

Thanks!!
