Yes, a delaminated head is a possible cause. The other possibility is that somehow the ink is transferring from black to yellow by running under the head.

We can discard that possibility due to the black ink not being randomly deposited or smeared. The perfect fit to the nozzle pattern means it’s going through the yellow pathway.

Once the purge pattern has cleaned the yellow nozzles it will print fine until the printer rests for a bit and the problem returns. There is no black in yellow contamination while the printer is printing. So that makes me think it could be another reason (wishful thinking).

My take on that is that the flow rate of the cross-leak is more slow than the flow during printing.
