Designjet T790 service error 08:11

[tabcom]

The 08:11 service error has to be the most frustration error code of the complete line of Designjet Printers.

Regretfully, HP did not engineer this error code to specifically identify the part that is defective. To HPs credit, they did engineer later models to provide more detail feedback.

Here is the frustration, the 08:11 service error requires a 'best guess' approach.

The defective part may be one of the following:

1. Defective Hard Disk

2. Defective Formatter Board

3. Defective Main Board

4. Defective Fan

5. Defective Control Panel

Replacing the HD and\or Formatter Board is easiest to trouble shoot.

Replacing the Main Board and\or Fan is time consuming with dozens of screws to remove and reassemble. I can't personally confirm the Control Panel fixed it. Never got to #5 on the best guess list. I've read countless post saying 'try this'. I'm posting here hoping for a fresh take.

Here is the most recent service call I'm dealing with.

I’ve tried 2 different formatter boards and 2 different hard drives (new) and no matter the combination I still get the 08:11 error and led 1 is solid on.  I’ve tried putting the designjet firmaware on a flash drive and starting the plotter but it doesn’t see it and I always get the 08:11 error. 

Can you point me in the direction I should proceed?

Also experienced this issue with the T610, T1100, T770 models.

Does The plotter load from 1% to 100 %

Shouldn't T790 formatter came with HDD as one spare part?

It has been a while but every time I had 08:11 I can only order formatter+HDD. There was no option to order HDD separately from formatter and vice verse.

Formated hard disks are easily available.
