Certificate of volatility This is a statement regarding the volatility of customer data stored in memory. It also outlines how to securely erase data from the product. Types of memory Volatile memory The product utilizes 1024 MB of volatile memory used for temporary storage during the process of jobs, and for applications running on the operating system. When the printer is powered off, the memory is erased. Non-volatile memory The product utilizes non-volatile memory (EEPROM, Flash) containing the boot code and factory product configuration data required for the device to function. No customer print data is stored in non-volatile memory. There are no steps to clear this data. Mass Storage memory The product contains an internal Hard Disk Drive (HDD) or Solid State Disk (SSD) to store customer data, device operating system, applications, digitally signed firmware images, persistent data, and temporary data used for processing and system functions. This data can be erased using the device BIOS menu, embedded web server (EWS), and HP Web Jetadmin with the following commands: ● Erase and Unlock Encrypted Disk - This changes the encryption keys rendering all data unreadable ● Secure Disk Erase - Industry standard ATA Secure Erase. Overwrites all data on the disk ● Secure Storage Erase - Erases temporary files and job data by overwriting information one or three times (HDD only) ● Secure File Erase - Erases files when jobs finish processing by overwriting them one or three times (HDD only) Secure Storage Erase and Secure Disk Erase features comply with U.S. NIST Special Publication 800-88 Guidelines for Media Sanitization.
