Removal precautions

CAUTION—SHOCK HAZARD: This product uses a soft power switch. It does not physically disconnect
the input AC voltage. To avoid the risk of electrical shock, always remove the power cord from the
printer when removal of the input AC voltage is required.
CAUTION—SHOCK HAZARD: To avoid the risk of electrical shock and to prevent damage to the printer,
remove the power cord from the electrical outlet and disconnect all connections to any external devices
before you connect or disconnect any cable, electronic board, or assembly.
CAUTION—HOT SURFACE: The inside of the printer might be hot. To reduce the risk of injury from a hot
component, allow the surface to cool before touching it.
CAUTION—PINCH HAZARD: To avoid the risk of a pinch injury, use caution in areas marked with this
label. Pinch injuries may occur around moving parts, such as gears, doors, trays, and covers.

Data security notice

Identifying printer memory
•
Volatile memory—The printer uses standard random access memory (RAM) to buffer user data temporarily
during simple print and copy jobs.
•
Nonvolatile memory—The printer may use two forms of nonvolatile memory: EEPROM and NAND (flash
memory). Both types are used to store the operating system, printer settings, network information, scanner
and bookmark settings, and embedded solutions.
•
Hard disk memory—Some printers have a hard disk drive installed. The hard disk is designed for printer-
specific functionality and cannot be used for long‑term storage of data that is not print-related. The hard
disk does not let users extract information, create folders, create disk or network file shares, or transfer FTP
information directly from a client device. The hard disk can retain buffered user data from complex print
jobs, form data, and font data.
The following parts can store memory:
•
Printer control panel
•
User interface controller card (UICC)
•
Controller board
•
Optional hard disks
Note: The printer control panel and controller board contain NVRAM.
Erasing printer memory
To erase volatile memory, turn off the printer.
To erase nonvolatile memory, do the following:
1
From the control panel, navigate to Settings > Device > Maintenance > Out of Service Erase > Sanitize all
information on nonvolatile memory.
2
Select Sanitize all information on nonvolatile memory, and then select ERASE.
