HP Printhead problem

[Hog Wild graphics]

I was printing a banner and had my first head strike. Now printer is giving error message to check print head plot status. So I ran a test here is my images. Do I need to change all heads except the M-LM?

I have ran printhead cleaning twice with no improvement.

Did you try pulling all the heads and reseating them?

pull out the light magenta head, clean it with alcohol with a swab, put it back in. Profit.

I pulled printheads and cleaned them about to test print. But to me it looks like the M-LM is printing good and the other heads are not by the test prints. Am I missing something?

See if you get any improvement after an automatic head align. Shot in the dark
