Type of printer head is incorrect

[vasmiz]

Hi there

I have an MG 7150. I get an error message: Type pf printer head is incorrect. I read an advice in the community posts that the problem could be fixed if I could remove the printerhead and unplug the printer for 5-10 minutes. Unfortunately, I cannot remove the ink tank, as I cannot find any levier to do so. Can you please advise?

First remove the ink tanks.

Then open the grey lever and remove the printhead
