Overview Solid State Drives (SSD), Solid State Modules (SSM), and enhanced MultiMediaCard (eMMC) technology used in some models of HP printing devices do not support data overwrite or native encryption. Files deleted from these storage devices are not immune from forensic recovery. To protect customer data, HP is implementing firmware encryption to specific areas of the storage device containing job data.
Erase Job Data The Erase Job Data command will include an option for “Secure Cryptographic Erase” when Secure Volatile Storage is active. The other erase selections will be unavailable. If these options are not present for Secure Cryptographic Erase, change the encryption from the default AES128 to AES-256. Ram Disk Replacement Secure Volatile Storage replaces the RAM Disk feature on supported devices for storing job data.
