HP Designjet T120 Error code: 805DFF31

[cloudnavigator]

When the T120 is turned ON the HP logo displays then you get a blue screen with "805DFF31" displayed.  You cannot turn OFF the T120 at this point.  You must unplug it and plug it back in order to turn in ON, but you will get the same error.  There is no sound of movement in the T120, and it doesn't make an beeps or other interesting sounds. 

Looking for this error code on HP's support website turned up nothing.  Other T120/T520 owners have posted equally strange error codes that start with "805Dxxxx" but everyone seems equally clueless as to what they mean.  Why can't HP provide a useful error code that can be referenced?

Hi,

Please 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). If it is covered under warranty.

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

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
