Code
0100 EEPROM (U12) write error
• When it cannot make normal to access
to the EEPROM (U12) which is
installed in the socket of the engine
controller PWB (KP-1054).
(The total counter, serial number and
engine parameter etc. are stored in the
EEPROM [U12]).
0150 EEPROM (U11) write error
• When it cannot make normal to access
to the EEPROM (U11) which is
mounted on the engine controller PWB
(KP-1054).
0420 Paper feeder communication error
• When turning on power, the ASIC of
the engine controller PWB (KP-1054)
recognized the optional paper feeder
PF-60, but when it becomes not be
able to communicate from the middle.
After the error occurring, when power
source is turned on/off, there are times
when the paper feeder is not recognized.
0460 Duplexer communication error
• When turning on power, the ASIC of
the engine controller PWB (KP-1054)
recognized the optional duplexer DU-
300, but when it becomes not be able
to communicate from the middle.
After the error occurring, when power
source is turned on/off, there are times
when the duplexer is not recognized.
