Error Message on Printer

[bsmith629]

I am receiving an error message of "printer head not installed, Install printer head" on my MP520" with a code of U051.  How is this handled?

Hello bsmith629,

If the Print Head is already installed, remove the Print Head once and then reinstall it. If the error is not resolved, the Print Head may be damaged.
