23-1. Memory Backup
Image Processing Board Backup RAM
• NVRAM (backup RAM) mounted on the Image Processing Board (PWB-B) stores the
Touch Panel-related adjustment values, and User's Choice and other settings as well as
counter values.
• NVRAM has a built-in battery that ensures that the contents of the memory are not lost
even when power to the copier and PWB-B is shut down, or when NVRAM is demounted
from the PWB-B.
N O T E S
• When replacing the PWB-B, demount NVRAM from the old PWB-B and mount it to a new
PWB-B.
• When the NVRAM is replaced, it is necessary to make all settings again to restore the
contents of the memory. For the setting values, refer to the Adjust Label and those before
replacement.
