Setting Up Password Encryption (WF-C879R)

You can set up password encryption to protect confidential information stored in the product. You can also back up the encryption key that is stored in your product's Trusted Platform Module (TPM) chip to a USB flash drive.
Note: Make sure you have a USB flash drive with at least 1MB of storage space to back up the encryption key.
If the TPM chip fails, you cannot replace it or access any confidential information stored on your product. Printer functions are still available, but the password encryption feature cannot be used. Contact Epson for support.
