Removal precautions
CAUTION—SHOCK HAZARD: For personal safety and to prevent damage to the printer, remove the
power cord from the electrical outlet before you connect or disconnect any cable, electronic board or
assembly.
Data security notice
1 This printer contains various types of memory that are capable of storing device and network settings,
information from embedded solutions, and user data. The types of memory, along with the types of data
stored by each, are described below.
• Volatile memory—This device utilizes standard Random Access Memory (RAM) to temporarily buer
user data during simple print and copy jobs.
• Non-volatile memory—This device may utilize two forms of non-volatile memory: EEPROM and NAND
(flash
memory). Both types are used to store the operating system, device settings, network information,
scanner and bookmark settings, and embedded solutions.
• Hard disk memory—Some devices have a hard disk drive installed. The printer hard disk is designed
for device-specific functionality and cannot be used for long term storage for data that is not print-related.
The hard disk does not provide the capability for users to extract information, create folders, create disk
or network file shares, or transfer FTP information directly from a client device. The hard disk can retain
buered user data from complex print jobs, as well as form data and font data.
To erase volatile memory, turn o the printer.
To erase non-volatile memory, see the menu item under
“Configuration menu” on page 190 pertaining to
this.
To erase the printer hard disk, see the menu item under
“Configuration menu” on page 190 pertaining to
this.
The following parts are capable of storing memory:
• printer control panel
