HP DesignJet T790 stuck at 33 or 34%. (sometimes it show 08:04 error)

[Keeper]

Hi there!
I need help with HP DesignJet T790. It stuck during initialization. Usually at 33 or 34%. Sometimes it show 08:04 error during initialization. Sometimes initialization process finishes completely, but in couple of minutes it show 08:04 error.
What is that? Formatter board? HDD?

Thank you in advance.

My money would be on the hard drive failing. CR650-67001 Designjet T790, T1300 SATA Hard Disk Drive with FIRMWARE (

You can try removing the printheads and ink cartridges, just to rule out a consumable.
