Description: Service NVRAM Failure Error NV part on system board.
Remedy: • POR the printer. • If the problem persists, then replace the controller board.
Code: 952.xx
Description: Service NVRAM Failure A recoverable MVRAM Cyclic Redundancy Check (CRC) error occurred. n is the offset at which the error occurred.
Remedy: Performing a POR will clear this error.
Code: 953.xx
Description: Service NVRAM Failure NVRAM chip failure with mirror.
Remedy: • POR the printer. • If the problem persists, then replace the UICC card. For CS310 models, see “Operator panel removal (for CS310 models only)”. For CS410 and CS510 models, see “Operator panel removal (for CS410 models only)” and “Operator panel removal (for CS510 models only)”.
Code: 954.xx
Description: Service NVRAM Failure The NVRAM chip failure with controller part.
Remedy: • POR the printer. • If the problem persists, then replace the controller board.
Code: 955.xx
Description: Service Code CRC <loc> The Code ROM or NAND flash failed the Cyclic Redundancy Check (CRC) check or the NAND experienced an uncorrectable multi-bit failure. <loc> indicates the source of the failure and has one of the following values: • CRC Failure: The source is a failing package indicated by Pn where n is the package number. This error could occur on a controller with ROM or NAND flash and could occur as a result of the CRC check done when the machine is powered on. The range of package numbers is from 0 to 15. • Error Correction Code (ECC) Failure: The source is a failing page indicated by Bn where “n” is the page number. This error occurs only if a multi-bit failure is detected during the ECC execution. Single bit failures will be corrected automatically and will not result in a service error. The range of page numbers is from 0 to 1023.
Remedy: • POR the printer. • If the problem persists, then replace the controller board.
Code: 956.xx
Description: Service Controller Board Controller board failure. Processor failure. Check on .02 for fan error.
Remedy: • POR the printer. • If the problem persists, then replace the controller board.
