Overview
RAM Disk provides volatile temporary storage for the print data. Upon shut down of the device or loss of power
the RAM Disk loses any data held in memory. The RAM Disk function meets the needs of customers with
requirements to have no user print data written to mass storage, such as a hard disk, eMMC or SSD.
With the installation of a supported HP DIMM, supported single-function printers can be configured to use the
DIMM as RAM Disk. Once enabled, all print data that would have been written to mass storage will instead flow
through the RAM Disk for print processing.
The supported accessory RAM DIMM modules for Ram Disk, HP 1GB 90-Pin DDR3 DIMM (2NR03A) and HP 2GB
DDR3x32 144-Pin 800MHz SODIMM (2NR09A), are Trade Agreements Act (TAA) compliant.
The RAM Disk feature is available on HP FutureSmart Enterprise single-function products introduced after
January 2015 and running HP FutureSmart firmware 4.8 or higher. See Supported Printers for a complete list
of supported products and compatible TAA compliant DIMM accessories.
Data written to RAM Disk
When the RAM Disk is enabled, the print data is sent to the RAM Drive. All other data, including system data and
configuration data will remain on the original device drive.
If the RAM Disk is enabled on a system that already has sensitive content on the mass storage device, the data is
deleted upon enabling of the RAM Disk. This is done via a cryptographic erase of the storage device.
System requirements
RAM Disk functionality requires FutureSmart 4 firmware version 4.8 or higher to be installed on the printer. The
product firmware must be installed prior to configuring the device for RAM Disk.
