If any body face the below related proble of HP designJet T120/t520 printer relted, you must follow the below process:
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
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:
I hope that answers will support to concern adequately. Let me know! Good luck

Everyone always suggest the main board where in fact 90% of the time the error is caused by the firmware usb drive. They are available from hp parts for 25.00 which is the way I would first go since it is a lot cheaper then the main board which comes with the same drive. The part number is CQ890-67105.
Just go to the link below and put the part number in to order.

You just confirm your product region if your printer and thumb driver both of purchase from same region. Then you may soft reset the printer entering service mode and let's try what happened.
I hope that will help to you. If you need anymore help you may feel free knock to us.
