Epson Sure Colour P800 Issue URGENT?

I have an epson SC-P800 it had a paper jam a few days ago and now is running prints with ink drops. I have cleaned the nozzle heads and the pump cap. Currently doing head alignment and the other maintenance items. It seems there is some black appearing in the yellow a little. Need help urgently. I do have pictures as the ink drops are at the top and slight to the top left hand side and right hand side always in those positions and no where else. Thank you Samantha
