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. Disconnect any connections between the printer and the PCs/peripherals.
Data security notice
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 buffer 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 buffered
user data from complex print jobs, as well as form data and font data.
To erase volatile memory, turn off the printer.
To erase non-volatile memory, see the menu item under “Configuration menu” on page 240 pertaining to this.
To erase the printer hard disk, see the menu item under “Configuration menu” on page 240 pertaining to this.
The following parts are capable of storing memory:
•
printer control panel
•
UICC (User Interface Controller Card)
•
controller board
•
optional hard drives
Note: The printer control panel and controller board contain NVRAM.
After removing the old part, it must be returned to your next level of support
Handling ESD
‑
sensitive parts
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent
damage to ESD-sensitive parts, use the following instructions in addition to all the usual precautions, such as
turning off power before removing logic boards:
•
Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until you are ready to
install the part into the machine.
•
Make the least-possible movements with your body to prevent an increase of static electricity from clothing
fibers, carpets, and furniture.
