Securing the printerStatement of VolatilityYour printer contains various types of memory that can store device and network settings, and user data.Types of memory DescriptionVolatile memory Your printer uses standard Random Access Memory (RAM) totemporarily buffer user data during simple print and copyjobs.Non-volatile memory Your printer may use two forms of non-volatile memory:EEPROM and NAND (flash memory). Both types are used tostore the operating system, device settings, networkinformation, scanner and bookmark settings, and embeddedsolutions.Hard disk memory Some printers have a hard disk drive installed. The printerhard disk is designed for device-specific functionality. This letsthe device retain buffered user data from complex scan, print,copy, and fax jobs, as well as form data, and font data.Erase the content of any installed printer memory in the following circumstances:• The printer is being decommissioned.• The printer hard disk is being replaced.• The printer is being moved to a different department or location.• The printer is being serviced by someone from outside your organization.• The printer is being removed from your premises for service.• The printer is being sold to another organization.Disposing of a printer hard diskNote: Some printer models may not have a printer hard disk installed.In high‑security environments, it may be necessary to take additional steps to make sure that confidential data storedin the printer hard disk cannot be accessed when the printer—or its hard disk—is removed from your premises.• Degaussing—Flushes the hard disk with a magnetic field that erases stored data• Crushing—Physically compresses the hard disk to break component parts and render them unreadable• Milling—Physically shreds the hard disk into small metal bitsNote: Most data can be erased electronically, but the only way to guarantee that all data is completely erased is tophysically destroy each hard disk where data is stored.Erasing volatile memoryThe volatile memory (RAM) installed in your printer requires a power source to retain information. To erase the buffereddata, simply turn off the printer.Securing the printer 205
