770 toner CRUM problem

[InterfaceP]

Thanks for all your help guys. Sorry Milo you were a step ahead of me.

So my SW version is 1.6.0

I have 3.2.54 and 3.7 which one do you recommend I install? I know some systems you need to step up the SW versions.

Thanks again

None of them if your machine is 770 DCP
You have sw version for 700 - 700i DCP
You need pws tool for 770 and sw version 1.2 which is in fact 1.6.0 system software, 1.230.1 controller sw and 91.22.0 IOT sw.

I had a similar problem before and removing the battery from MCU board and reinstalling after 5 min resolved it

OK I'm at the end of my rope.

I reinstalled SW Version 1.2 and the same thing...

When I try to sync the serial numbers it fails. I have tried numerous times with the same results.

Sys2 (ESS NMM PWB) is blank on the Serial Sync screen, if I replace it with another (from a 700 with same PN) it appears on the screen but fails to sync.

I do get a 94-322 Second BTR Retract Failure.

I'm at a loss for what to do next.

I don't know how I missed this but I did. This worked for the SN Sync but I'm back to my original problem now. All of my consumable values are @ zero.

I found a Eureka for a 700 (not a 770) but when I executed the procedure I don't have the CRUM NVMs.csv its asking for in my V1.2 software pack.

Here is the procedure:

Problem:



All consumables at Zero percent life remaining after MCU NVM replacement.





When this part is replaced perform the following steps:

• Synchronize the serial number. This may not take the first time and can take several attempts.
• Once the serial number is synchronized, check software levels are compatible if not then resolve the software mismatch. If the machine is at V2.0 software load the script files that came with the software.
• Next Load the attached script file using the following directions;
  
  1. Save the attached script file to a location on your desktop that you will remember.
  2. Connect USB cable to X700 DCP and start NVM access Tool.
  3. Select NVM Access in the DC Quick menu.
  4. Select Open Script File. Browse to the file you have saved in step 1
  5. Select the 700DCP CRUM NVMs.csv script. Select Open Script File.
  6. Select Create Snapshot
  7. After the snapshot has been created select Restore Snapshot.
  8. When the NVM write is complete, select File then Exit. Select Cancel do not save the Machine Data file.
  9. Power off IOT using the switch at the top of the IOT. Wait until the? Blue? LED on the UI turns off
  10. Power ON IOT.
