5.3 SELF-DIAGNOSTIC MODE
5.3.1 RUN TIME DIAGNOSTICS
Throughout the operation of the machine all functions and components are moni-
tored. Should an error occur, a fault code is displayed. Many faults can simply be
corrected by the operator. In that case a picture shows the location of the fault with
a text message, such as ”Clear Misfeed(s)”. If the fault can not be corrected by the
operator, the text message ”Fault in area” is displayed. All messages regardless of
nature are always accompanied by a fault code. The operator manual lists the fault
codes that the operator can solve. This manual lists all fault codes. To correct the
fault, go to Fault Code Descriptions ( 4.1) .
5.3.2 POWER ON SELF TEST
At power on the program checks the EEPROM. It checks that it is present and not
corrupt. If not present or corrupt, the machine will lock-up. If present and not corrupt
the machine will enter normal operation mode unless:
A. The service mode is entered.
B. EEPROM reset is entered.
