Error code
Meaning
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.
4,000: PC (process control supervisor)....
4,001.40:
PC_DEV_FAULT_HEAD
_READ
Failure reading printhead NVRAM data: check the wiring
to the printhead, I
2
C bus and other hardware.
4,002.41):
PC_DEV_FAULT_HEAD
_ZEROS
Printhead NVRAM data was all 0s: has this printhead
been through normalization? If so, check wiring to
printhead.
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).
4,005.44:
PC_DEV_FAULT_DM_
CAM_ERR
Failure positioning drum maintenance cam during a drum
maintenance cycle: check drum maintenance cam
solenoid, clutch, home sensor, and related hardware.
4,009.
PC_DEV_FAULT_DM_
CAM_BEGIN
At the start of a drum maintenance cycle, when the drum
maintenance cam position should have been at blade
down, oil roller down, the drum-maintenance cam-home
sensor should have been TRUE and was instead FALSE.
Check the drum maintenance cam solenoid, clutch, home
sensor, and related hardware.
