Not only do you have a serious clog ,you have deflected nozzles.I only own a 7900 and 9890 but...
from the looks of that cleaning-capping station and all the crap sprayed around it, I'd be willing to bet there is a real problem with correct seating of the head on the capping station, those wipers look horrible, and with all kinds on gunk on the underside of the head, not to mention possibly a fried channel at this point.
I'd stay out of it! and let the "boss" get a tech in for some serious servicing!!!
How old is that machine and how much use does it get?
At some point they all need proper maintenance! ;-)
