Hi there and welcome
When you do the alignment, in the alignment page itself, yellow is not showing correct?
remove the ink cartridges and power off the printer then use a Q-Tip dabbed in alcohol (rubbing alcohol or something such as Vodka) then clean the inside of the yellow ink holder, especially at the bottom where the ink goes through. Try to also get on the underside and clean that as well.
Let it drive for 30 minutes, put the cartridges back in, turn on the printer and tell me how yellow then prints please.
