and printed a test page.
That is interesting- what did you get?
Meanwhile take a look at the connector tracks in the colour chamber and ensure they are Clean- an alcohol wipe and flexible to ensure contact with the cartridge.
If no joy
Remove connections then have a go at removing the case- check the ribbon connector to colour cartridge chamber. May have worked work loose.
Still no luck?
Throw it away and buy another printer -preferably not Lexmark
