5.1.2
Fatal Errors
Listed below are fatal errors. If a fatal error occurs, the machine may fail to store the error code
into the EEPROM or output it to the recording paper. To signal the fatal error, therefore, the
machine employs flash codes using the
ERROR
and
PAPER
LEDs in the following way to indicate
the error code in eight bits with the MSB first.
Error code
Probable causes
55
Write error into the work area of the RAM.
A5
Access to the EEPROM impossible.
Interpretation of flash codes using the
ERROR
and
PAPER
LEDs
If the
ERROR
LED flashes once, interpret it as "1"; if the
PAPER
LED flashes once, interpret it as
"0."
For example, error code A5 is expressed as "10100101" in eight bits with the MSB first, so the
ERROR
and
PAPER
LEDs will flash as follows:
5.1.3
Main PCB Uncustomized Error
In any of the following cases, a main PCB uncustomized error will occur and the machine will enter
the in-process inspection mode.
(1) A new main PCB (not a used board) is installed.
(2) The "Reserved" function (listed in Chapter IV, Section 4.2) in the maintenance mode is
mistakenly activated.
If the machine enters the in-process inspection mode (in which a sequence of the checks will be
automatically made), the
ERROR
and
PAPER
LEDs will flash at 0.5-second intervals. To exit this
mode, press the
COPY
,
FEED
,
COPY ALL
,
FEED
,
COPY ALL
, and
COPY
keys in this order
quickly. The
ERROR
and
PAPER
LEDs will go off.
