PIXMA MX922 Print head error messages after power supply replacement

[CraigB]

I have a Canon MX922 printer that is about 5 years old.  It wouldn't power up and I determined that it needed a new power supply.  I got one and installed it.  Now it does power up, but it is showing strange error messages that the print head is the wrong type and the right type needs to be installed.  Any ideas or suggestions on what I can do to solve this problem?  Thanks.

Try removing printer from wall power and press power on button a few times.

Thanks for the suggestion John.  I tried it and it still powers up and gives me the same error message "support code 1405" that says "The type of print head is incorrect.  Install the correct print head."
