When I printed this weekend, the yellow ink didn’t print.

Ran a test print then did a 24hr head soak, then another test print.

Photos are below

I also printed blocks of yellow without success.

Does anyone have other suggestions?

AND

Is this a timely issue to resolve (have to go out of town for family wedding later this week, will I be making the issue worse if I deal with it in 2 weeks. 
THANK YOU SO MUCH FOR ANY SUGGESTIONS OR NEXT STEPS
