I
CAUTION
Before removing any of the printer components, do the following:
1. If the data-in lamp on the operation panel is blinking or lit, wait until a
document or report is printed, then turn off the machine.
2. If there is a fax unit in the machine, print out all messages stored in the
memory, as well as the user-programmed items and the system
parameter lists.
3. Turn off the main switch and disconnect the power cord, the telephone
cable(s), and the Ethernet cable.
4. If a fax unit, PC fax expander, or ISDN G4 is installed, remove them
before removing the printer controller.
5.2 CONTROLLER
NOTE: 1) When replacing the controller board, remove the NVRAM (IC26) from
the defective board, then install the NVRAM on the new board.
2) If the controller does not start up after a firmware update, try to boot
from the IC card and download the firmware. If that does not work, you
may need to replace the controller board. Refer to section 4.5.3 (Error
Recovery) for details.
1. Remove the covers.
2. Remove the controller (3 screws).
3. Remove the optional component(s) and the NVRAM from the controller, then
install them on the new controller.
4. Install the new controller.
5. Turn on the machine and print the Printer Configuration Page ([User Tools] –
[Printer] – [List Print]).
Ensure that all the controller settings are restored.
