Certificate of volatility This is a statement regarding the volatility of customer data stored in memory. It also outlines how to erase secure data from the device. Types of memory Volatile memory The MFP utilizes volatile memory (64MB on the board and 256MB installed, for a total of 320MB) to store customer data during the printing and copying process. When the MFP is powered off, this volatile memory is erased. Non-volatile memory The MFP utilizes non-volatile memory (EEPROM) to store system control data and user preference settings. No customer print or copy data is stored in non-volatile memory. This non-volatile memory can be cleared and restored to factory defaults by performing a Cold Reset or Restore Factory Defaults from the control panel. Hard-disk-drive memory The MFP contains an internal hard disk drive (40GB or larger) that may retain data after the MFP is powered off. The MFP also may contain additional optional compact flash storage, or an external EIO hard disk. Data stored in these devices may be from incoming/outgoing fax or email files, stored copy or print jobs, fax or email address books, or third-party solutions. Some of this data can be erased from the control panel of the MFP, but most must be erased using the Secure Storage Erase features available within HP Web Jetadmin. Secure Storage Erase features comply with U.S. Department of Defense (DOD) specification 5220-22.M. 324 Appendix D Regulatory information ENWW

Certificate of volatility
This is a statement regarding the volatility of customer data stored in memory. It also outlines how to
erase secure data from the device.
Types of memory
Volatile memory
The MFP utilizes volatile memory (64MB on the board and 256MB installed, for a total of 320MB) to
store customer data during the printing and copying process. When the MFP is powered off, this volatile
memory is erased.
Non-volatile memory
The MFP utilizes non-volatile memory (EEPROM) to store system control data and user preference
settings. No customer print or copy data is stored in non-volatile memory. This non-volatile memory can
be cleared and restored to factory defaults by performing a Cold Reset or Restore Factory Defaults from
the control panel.
Hard-disk-drive memory
The MFP contains an internal hard disk drive (40GB or larger) that may retain data after the MFP is
powered off. The MFP also may contain additional optional compact flash storage, or an external EIO
hard disk. Data stored in these devices may be from incoming/outgoing fax or email files, stored copy
or print jobs, fax or email address books, or third-party solutions. Some of this data can be erased from
the control panel of the MFP, but most must be erased using the Secure Storage Erase features
available within HP Web Jetadmin. Secure Storage Erase features comply with U.S. Department of
Defense (DOD) specification 5220–22.M.
