Selftest not passed

What happened?

This warning appears when the printer requires certain selftests to be completed before performing the requested action. The printer shows the message "Selftests required to perform this action have not been completed. The action cannot be executed".

Selftests are built-in diagnostic checks that ensure the printer’s components are functioning correctly before proceeding with specific tasks. This helps prevent damage or failed operations.
