Epson WF 7110 - cartridge installed incorrectly error

[drawnwithapencil]

Hi,
I have cleaned the print head as I wasn't getting ink coming through. Unused for a week and in a warm room caused it I recon' After cleaning I have got the cartridges not installed correctly warning and can't get past this. The ciss cartridge has clicked in place so I don't know what else to do. I did notice when I tokd the cartridge out to clean the print head that the brass connectors at the back of the print head for the yellow cartridge was raised to the top of the housing. I managed to push it into place with my finger nail.
Any ideas what I can do please?
Many thanks
Sue
