Fault Codes

Fault Code Definition Table

The following paragraphs will assist you in decoding the information contained in the
fault codes.
■
The failing system (XX,yyy.zz)
■
The failing subsystem (xx,YYY.zz)
■
The type of problem (xx,yyy.Zx).
■
The print engine copy count (xx,yyy.zz:123) when the error occurred.
Program faults are indicated by a 6 in the tenths place of the fault code
(xx,yyy.6z).
Unfortunately, there are too many program faults to enumerate them all
and most program faults will not mean anything unless you are intimately familiar
with the code base. Some of the more common program faults are documented in this
section.
Note
In customer mode, program faults cause the printer to automatically reboot up to
3 times within 72 hours or 1000 pages and no message is displayed on the front
panel. The fault codes are saved into non-volatile memory and can be retrieved
from the fault history.
CPU exceptions are indicated by a 7 in the tenths place of the fault code
(xx,yyy.7z). The error code indicates both the PowerPC exception number and the
region of firmware that was executing when the exception occurred; Engine,
PostScript, Network, or Operating System.
Note
A CPU exception can either be caused by hardware or firmware error. Refer to
the infoSMART knowledge base for descriptions of the most common faults.
Device faults are indicated by a 4 in the tenths place of the fault code
(xx,yyy.4z). Some of the more common device faults are documented in this
section.
