Error code
Meaning
2,000: System fault I/O board...
2,001.40:
SY_DEV_FAULT_IO_
RIGHT
The engine can not detect the presence of the right I/O
board. Ensure the connections are good.
2,002.40:
SY_DEV_FAULT_IO_
LEFT
The engine can not detect the presence of the left I/O
board. Ensure the connections are good.
4,000: PC (process control supervisor)....
4,001.40 (0x2401):
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 (0x2402):
PC_DEV_FAULT_HEAD
_ZEROS
Printhead NVRAM data was all zeros: has this printhead
been through normalization? If so, check wiring to
printhead.
4,003.42 (0x2403):
PC_DEV_FAULT_HEAD
_ONES
Printhead NVRAM data was all ones: has this printhead
been through normalization? If so, check the wiring to the
printhead.
4,004.43 (0x2404):
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 (0x2405):
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.
4,009.48 (0x2409)
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.
