HP Laserjet Enterprise M507 printer is displaying an error message 33 04 05  unknown TPM. How to solve it. The printer is bright new from the box.

 

When scrolling down the error message it shows that the system is using an unknown TPM module to protect data.The TPM module currently installed is unexpected. Return the original TPM module.

You need to perform a hard disk reset through the preboot menu. If you try that twice and still get the error, you need to remove the hard disk and the TPM module and perform a cold reset. Be careful removing the TPM because if damaged the whole printer will need to be replaced. As it is brand new I would contact the vendor about a DOA replacement.
