Error codes indicate the following:
the failing system ( XX ,yyy.zz)
the failing subsystem (xx, YYY .zz)
the actual problem (xx,yyy.ZZ).
the print engine copy count (xx,yyy.zz:123) the error occurred on.
Codes from 24,000 through 24,999 are engine failures reported by the PostScript
controller. They are not stored in the fault history table of the NVRAM. They
are reported when the engine has been stuck in a state for 25 minutes.
Meaning
Failure reading printhead NVRAM data: check the wiring to the
printhead, I
Printhead NVRAM data was all zeros: has this printhead been through
normalization? If so, check wiring to printhead.
Printhead NVRAM data was all ones: has this printhead been through
normalization? If so, check the wiring to the printhead.
Printhead NVRAM checksum failure: the data within the printhead
NVRAM has been corrupted. Check the the printhead ribbon cable and
associated connections.
Failure positioning drum maintenance cam during a drum maintenance
cycle: check drum maintenance cam solenoid, clutch, home sensor, and
related hardware.
Calibration failure: Target Volt-Sec Area of 300 dpi could not be
achieved. "Head Adjust" head drive voltage may be incorrectly set.
Possible hardware failure on printhead.
Calibration Failure: Target Volt-Sec Area of 600 dpi could not be
achieved. "Head Adjust" head drive voltage may be incorrectly set.
Possible hardware failure on printhead.
Failure to advance the drum maintenance tray sensor interrupt flag. It
has been in the new tray state for too long. Check the hardware.
At the start of a drum maintenance cycle, when the drum maintenance
cam position should have been at blade down, wick 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.
During the drum maintenance cycle, when the drum maintenance cam
position should have been at blade up/wick up, the drum maintenance
cam home sensor should have been FALSE and was instead TRUE.
Check the drum maintenance cam solenoid, clutch, home sensor, and
related hardware.
