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
No transitions are observed of the media width home sensor. The sensor
may be bad or the sensor is unplugged.
Failure reading printhead NVRAM data: check the wiring to the printhead,
2
I C bus and other hardware.
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 hardware. The printhead may need to be
renormalized (a manufacturing function).
Calibration Failure: 193x300 DPI waveform could not be generated. Check
the hardware. The head may need to be renormalized.
Calibration failure: Target Volt-Sec Area of 300 dpi could not be achieved.
Check the hardware. The printhead may need to be renormalized.
Calibration Failure: Target Volt-Sec Area of 600 dpi could not be achieved.
Check the hardware. The printhead may need to be renormalized.
Failure to advance the drum maintenance oiling mechanism. It has been in
the new state for too long. Check the hardware.
Timeout during head adjust. A twenty minute timer elapsed before the exit
head adjust command was executed. The only recovery possible is to cycle
the power switch.
This printhead's NVRAM contains a format of data not supported by this
version of firmware. The printhead or firmware must be replaced.
Ambient temperature is less than ten degrees Centigrade. The printer
cannot be warmed up under these circumstances.
