Wasnt this a firmware issue?What level of firmware are you running..also what version of system software is the Fiery running?...Si

[mr.propper]

I have checked with firmware vers.40, 50 and 60.
The fiery runs with 2.0

This problem c-4850 also appears without Fiery.

Hallo,

i have solved this problem.

The engine has self change the HDD to "faulty part isolation" with software-switch 18 bit 7 to 1.:mad:

After HDD-aktivation with SW-switch 2-0 to 1 and 18-7 to 0 appears error C-D0E1.:eek:

I replaced the HDD/K and i carry out "Replacement of the Hardisk" from service-manual and that was fine.:)

Lucky greetings
