• Remedy: Step 1 a Remove the controller board shield. See “Controller board shield removal”. b Check the cables on the controller board for proper connection. Are the cables properly connected? Go to step 2. Go to step 3. Step 2 Replace the controller board. See “Controller board removal”. Does the problem remain? Contact the next level of support. The problem is solved. Step 3 Reconnect the cables, and then reset the printer. Does the problem remain? Contact the next level of support. The problem is solved.

• Code: 938
• Description: 938.01 Board level was not obtained. 938.02 Time out waiting for bullet serial data to be updated. 938.03 NVM_OK was not received from NV2 server for successfully submitted request. 938.04 Over temperature condition detected.
• Remedy: Replace controller board

• Code: 950.xx
• Description: 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
• Remedy: Step 1 Verify if the control panel has been replaced. Has the control panel been replaced? Go to step 2. Go to step 3. Step 2 Replace the control panel with a new, and not previously installed, UICC card. See “Control panel removal”. Does the problem remain? Go to step 3. The problem is solved. Step 3 Verify if the controller board has been replaced. Has the controller board been replaced? Go to step 4. Go to step 5. Step 4 Replace the controller board with a new, and not previously installed, controller board. See “Controller board removal”. Does the problem remain? Go to step 5. The problem is solved. Step 5 a Turn the printer off for ten or more seconds. b Turn the printer back on. Does the problem remain? Go to step 6. The problem is solved. Step 6 Clear the NVRAM of the printer: a Turn the printer off. b With the printer off, press and hold buttons 6, 7, and 8 on the keypad. c Turn the printer on. d When Restoring Factory Defaults appears, release the buttons. Note: If the printer looks up on the Restoring Factory Defaults, then wait two minutes, and then turn the printer off. After ten seconds or more, turn the printer back on without holding down any buttons. Does the problem remain? Go to step 7. The problem is solved. Step 7 Replace the control panel. See “Control panel removal”. Does the problem remain? Go to step 8. The problem is solved. Step 8 Replace the controller board. See “Controller board removal”. Does the problem remain? Contact the next level of support. The problem is solved.

• Code: 951.xx
• Description: Error NV part on system board.
• Remedy: Replace controller board

• Code: 952.xx
• Description: 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: NVRAM chip failure with mirror. 1 POR the printer. 2 If the problem persists, replace the UICC card.
• Remedy:

• Code: 954...958
• Description: 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 multibit 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. 956.xx Controller board failure. Processor failure. Check on .02 for fan error. 957.xx Controller board failure. ASIC failure. 958.xx Printer has performed more than 100 “shift and reflash” operations as a result of ECC bit corrections.
