main body firmware and the internal devices
of the scanner.
Also, it can be checked by the user mode
“Maintenance” using the operation panel ex-
cepting the [SERIAL NUMBER].

[SERIAL NUMBER]
Special serial number for main body
Note:
The [SERIAL NUMBER] above could
not be changed in the market. If you re-
placed the control PCB to the service
parts, this number does not display.
4. Error History
This is used to check the error code and
occurrence time. Displays up to 8 errors.
Figure 5-215
Refer to the “I. ERROR DISPLAY” to the
contents of error code.
Note that not all errors are displayed. For
example, errors occurred before scanning,
cover open (C001/C009), and document re-
maining (P000), or error could not record,
EEPROM writing error (E086) and others.
And only the first error code is displayed,
such that the error indicated may differ from
the observed error.
Also, while the computer is not connected
or the computer does not control the time, oc-
currence time cannot be displayed.
