HP Designjet 800, 800ps, 500ps hard disk drive for the formatter.
One of the weak points of the HP Designjet 800 is the hard disk drive of the formatter. If this disk drive fails, the printer normally displays error code 05:10.
The hard drive contains encrypted software for the printer. Thus, replacing it with a normal standard disk drive is not an option.
Replacing the hard drive is easy. The formatter board can be removed by unscrewing two thumb screws after which it can easily be removed. You can then unscrew the hard drive from the main circuit board and insert the new hard drive.
The HP spare part number is: c7779-60254
12 months guarantee
If replacing the hard drive does not solve the problem, you can return the hard drive.
