Hi,

Try isolating the printer, remove inks, printhead, connectivity cables, another power outlet and then turn the printer on.

If you still have the problem, please replace the Main PCA and Encrypted Kit (P/N: CQ891-67019)

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.

Thanks,
Rashed

Replacing the encrypted chip solved the problem.

1. Remove and try without consumables 

2. Check and upgrade plotter FW if its older using USB procedure

3. If issue persist then contact HP solution center
