6.3. ERROR INDICATION
If the self diagnostics find an error, the error is displayed by a combination of
the four LEDs on the Scanner and the ADF. If the dip switches on the rear of
the machine are set up for normal operation, the error is indicated roughly for
users. When the dip switches are set to the self diagnostic mode position, the
system error is indicated in detail for technicians.
