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.
For more information on how to update the Enterprise printer firmware, please refer to document titled HP
Enterprise - Update the firmware.
Enable RAM Disk
Follow these steps to enable RAM Disk:
1. Power the printer off.
2. Install the DIMM in the printer according to the DIMM installation instructions.
3. Power the printer on and wait for the printer to come to the Ready state.
4. Open a web browser.
5. In the URL field, type the IP address of the printer and then press Enter.
NOTE: If the web browser displays a message indicating that accessing the website might not be safe,
select the option to continue to the website.
Accessing this website will not harm the computer. This message is received if the printer enforces HTTPS.
6. Select the Information tab, click Configuration Page to view the printer information (Figure 1). Verify the
DIMM shows in the installed personalities and options.
Figure 1: EWS - Configuration Page
7. Select the Security tab, and then select the Protect Stored Data in the left navigation menu.
4
8. Under RAM Disk Settings section, select the Enable RAM Disk check box. (Figure 2).
Figure 2: EWS - Enable RAM Disk in the Security tab
9. Click Apply. A restart of the printer is required to activate RAM Disk.
10. Click Restart Now. If desired, select Restart Later.
NOTE: HP recommends securing the formatter with a Kensington lock via the Kensington lock port.
See the printer manual for additional information.
To verify RAM Disk is enabled after the printer restart:
1. Open the printer Embedded Web Server.
2. Select the Security tab, and then select the Protect Stored Data in the left navigation menu.
3. Under the Drive Status section, in the Drive Content column, verify that RAM Drive is listed, and the Job
Data is displayed. (Figure 3).
NOTE: The Encryption Status will list with a warning “Status Disk cannot be encrypted.” This is means
that the RAM Drive is not self-encrypting.
NOTE: There is no customer-facing method or interface to directly access information stored in the RAM
Drive. Upon shut down of the device or loss of power, the RAM Disk loses any data held in its memory.

The configuration page in the Embedded Web Server will also display the RAM Disk Size under the Memory
column (Figure 4)

Disable RAM Disk
1. Open a web browser.
2. In the URL field, type the IP address of the printer, and then press Enter.
NOTE: If the web browser displays a message indicating that accessing the website might not be safe,
select the option to continue to the website.
Accessing this website will not harm the computer. This message is received if the printer enforces HTTPS.
3. Select the Security tab, and then select the Protect Stored Data in left navigation menu.
4. Under the RAM Disk Settings section, uncheck the Enable RAM Disk check box. (Figure 5).

5. Click Apply. A restart of the printer is required to deactivate RAM Disk.
6. Click Restart Now. If desired, select Restart Later.
7. The DIMM accessory can now be safely removed from the printer, if desired.
RAM Disk Error 33.03.07
The RAM Disk error 33.03.07 can be displayed on the BIOS menu in three different scenarios:
• If the DIMM accessory is removed from the printer prior to disablement via the Embedded Web Server.
• If the DIMM accessory is left off the formatter during a printer repair.
• If the DIMM accessory fails.
In any of these scenarios, the printer boot process will stop at the pre-boot menu and post the 33.03.07 No
DIMM Installed message (Figure 6). This message is also logged in the Event Log (Figure 7).
Figure 6: Error message: 33.03.07 No DIMM Installed
Figure 7: Event Log Page
Resolve the error
To resolve the error, use one of the following solutions:
• Solution one: Reinstall the accessory DIMM onto the formatter as per the DIMM installation instructions.
Or
• Solution two: Disable the RAM Disk function from the Preboot menu, using the following instructions:
a) At the Preboot menu error code, press the Back arrow.
b) Press the down arrow to the Administrator menu. Press OK.
8
c) Press the down arrow to the Ramdisk Disable menu (Figure 8). Press OK.
Figure 8: Ramdisk Disable
d) When prompted, press OK to accept (Figure 9).
Figure 9: Accept Ramdisk Disable
e) Press the back arrow to return to the main menu.
f) Select Continue, press OK to resume the printer start up process.
