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.
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.
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.
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.
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.
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).
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).
