2,000: SYSTEM FAULT I/O BOARD...
2,001.40:
SY_DEV_FAULT_IO_
RIGHT
The engine cannot detect the presence of the right I/O board.
Ensure the connections are sound.
2,002.40:
SY_DEV_FAULT_IO_
LEFT
The engine cannot detect the presence of the left I/O board.
Ensure the connections are sound.
2,002.61:
SY_PROG_FAULT(2)
Queue Initialization failure during execution of sy_app_init()
(early initialization code), the engine firmware was unable to
initialize the queues used for inter-task communication. This
indicates a failure in the call to function sy_creat_queues().
2,003.62:
SY_PROG_FAULT(3)
Can’t start service diagnostic tasks, (while booting into diagnostic
mode) during execution of sy_app_init() (early initialization code),
the engine firmware was unable to start the service diagnostics
task.
4,000: PC (PROCESS CONTROL SUPERVISOR)....
04,001.40:
PC_DEV_FAULT_HEAD_
READ
Failure reading printhead NVRAM data: check the wiring to the
printhead, I
2
C bus and other hardware.
May also be related to ESD.
04,002.41):
PC_DEV_FAULT_HEAD_Z
EROS
Printhead NVRAM data was all 0s: has this printhead been
through normalization? If so, check wiring to printhead.
May also be related to ESD.
4,003.42:
PC_DEV_FAULT_HEAD_
ONES
Printhead NVRAM data was all 1s: has this printhead been
through normalization? If so, check the wiring to the printhead.
4,004.43:
PC_DEV_FAULT_HEAD_
CHECKSUM
Printhead NVRAM checksum failure: the data within the
printhead NVRAM has been corrupted. Check the hardware and
wiring. The printhead may need to be renormalized (a
manufacturing function).
4,006.67:
PC_PROG_FAULT(0x06)
This indicates that an undefined message was found by the
processor. This may be caused by ESD. Check grounding and
media issues.
