HP DesignJet T520
Microsoft Windows 10 (64-bit)

Has anyone had the error code B2887D64 on the T520 Printer?

Printed fine this morning but after some power outage when plotter came back on it had this error code.


I have not been able to find the source of the problem, google has no answers, HP websites have no answers, I am at my wits end?

Any help someone?

It is inside the plotter on Main PCA in usb slot /.

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:

Thank you Rasheddul!


I have opted for taking it to the supplier I bought it from, as they have a technical service centre, so they can repair and service the machine at the same time.

The parts can be ordered via e-bay as you say, but delivery to South Africa doubles or even trebbles the price.

HP South Africa are pretty useless when it comes to support.  I am still waiting for them to respond to my e-mails.

Suspect that they will contact me when the machine is already repaired and running again... 😞

The causes are also exactly as you described. We are blessed (:-() with load shedding and the on and off of the power grid caused this issue.  I have now invested in a UPS for my plotter also to avoid these issues in future.

Thank you again for your time and assistance!
