I have a blue screen error message BA7E730C at startup and can not track down what this may be?
Does anybody have any ideas? The printer refused to turn off so I did hold down power button while inserting the power cord trick which seems to have worked but I am stuck with the error code.

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
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:
I hope that answers will support to concern adequately. Let me know! Good luck
