950.xx | There is a mismatch between controller EEPROM and mirror. - 950.00 through 950.29 codes: mismatch between controller and mirror
- 950.30 through 950.60 codes: mismatch between secure and controller
| See NVRAM mismatch failure service check. |
950.10 | An NVRAM mismatch error occurred. |
951.xx | Error NV part on system board. | See Controller board removal. |
952.xx | A recoverable MVRAM Cyclic Redundancy Check (CRC) error occurred. n is the offset at which the error occurred. | Performing a POR will clear this error. |
953.xx | NVRAM chip failure with mirror.  POR the printer. If the problem persists, replace the UICC card.
| See Control panel removal. |
953.99 | A control panel NVRAM error occurred. | See NVRAM mismatch failure service check. |
954.xx | The NVRAM chip failure with controller part. |
955.xx | 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.
