3-8 WorkCentre C2424 Service ManualFault Code Error Message TroubleshootingFault Code Error ReportingFault codes are saved to NVRAM and can be retrieved from the system’s fault history.All procedures that ask for a test to be run are referencing tests from within the“hidden” service diagnostics menu. For more information on service diagnostics tests,their results, and how to enter into diagnostic mode, see "Service Diagnostics" onpage 4-4.In normal customer mode, the system will reboot each time an error occurs. If three ofthe same errors occur within 72 hours, or 1000 pages, the fault will be displayed onthe system’s control panel.Interpreting Fault Codes■ Failing system (XX,yyy.zz)■ Failing subsystem (xx,YYY.zz)■ Checksum (xx,yyy.zZ■ Type of problem (xx,yyy.Zx)■ Print engine copy count (xx,yyy.zz:123) when the error occurred(xx,yyy.4x) Device faults are indicated by a 4 in the tenths place of thefault code. This indicates a hardware problem. The most common device faultstroubleshooting procedures are documented in this section.(xx,yyy.6x) Program faults are indicated by a 6 in the tenths place of thefault code. Unfortunately, there are too many program faults to enumerate them alland most program faults will not mean anything unless you are intimately familiarwith the code base. Some of the more common program faults are documented in thissection.(xx,yyy.7z) CPU exceptions are indicated by a 7 in the tenths place of thefault code. The error code indicates both the PowerPC exception number and theregion of firmware that was executing when the exception occurred: Engine,PostScript, Network, or Operating System.NoteA CPU exception can either be caused by hardware or firmware error. Refer tothe infoSMART Knowledge Base for descriptions of the most common faults.
