Printer saying Type of Print head is incorrect, install correct print head


I know lots of people have had this before. Mine is a Canon MG7150 printer which I haven't found mentioned.  I tried the inssturtion of removing all the ink cartridges and lifting the grey lever on the ink tank but there isn't a grey lever on the MG7150.  It has started doing this since I installed Windows 365 on my ageing iMac (which I am about to replace). (Can't help feeling the two things are related?).  How can I get the machine printing again.  I need it!
