Blue Screen Error B85F28C8

HP Recommended
Designjet T520 (2014 manufacture)

We have a 2014 Designjet T520 that uses 36" paper.  It will not start up and it shows a Bluescreen Error B85F28C8.  I'm trying to find out what it means and if there are parts that could be replaced to  fix it. 

 

I've seen that there is a kit CQ890-67097 that can be used for some bluescreen errors, but I have not been able to find any information on the specific error that our printer is showing, and can't find a reference to it on this site.  I'm really hoping that we don't have to scrap our printer as the cost of a replacement isn't in the budget right now.  

 

Any assitance or advice would be greatly appreciated.  Thank you!

At first try to follow the below steps and get it fix by :

- Connecting the printer to another outlet

- Repacing the power cable

- Replacing the Main PCA (If you have replace Main PCA, it will solved the issue.)

 

Also try to Isolate the printer by removing any connectivity cables, printhead

 

Try removing the ink cartridges, printhead, paper, replacing the power cable and another power outlet. If you still have the problem, please replace the Main PCA (P/N: CQ890-67097)

N.B: Part No. CQ890-67081 is an older revision.

 

Main PCA - T120: P/N: CQ891-67013

Main PCA - T520: CQ890-67023 

 

 

Most of cases that kit will damage for voltage factualation and this one working as a ROM. 

 

 

 

It is my understanding that the new Main PCA should come with the USB with the FW. Make sure it is there before installing the new main PCA.


If problems with the FW, will not recommend you to use the old USB with the firmware again.

 

If not covered under warranty you may replace Encrypted chip which is failed on the mainboard inside the printer you can buy it on ebay/other's source:
