CD004 "failed to overwrite" error? This worked for me. I am not sure how complete the overwrite was but it blanked out all the addresses that used to show on the test sheet.
I tried the 35 hour(!) "overwrite" function but it kept getting CD004 error. This process allowed me to unlock printing function again and wipe the HD.
go to Service Mode (hit these buttons: utility/counters>details>stop>0>0>stop>0>1>Password:00000000>end
go to System Input, turn HD to NO, hit END, home screen will show "failed to overwrite data" again, turn main power switch off for 10 seconds and then turn it on again, home screen should show "all data overwritten"
Go to utility>admin management>Password:12345678>Format hard drive> Format is complete> turn main power off for ten seconds and then on again
Print function should be restored. Go into System Mode again and turn the hard drive back to YES/ON

I looked through the service manual for this and I see "tech rep mode" listed. I don't think you can access this from your digital screen, but look for it. Other than that it suggested opening the "front door" and closing it again with the power on to reset. Hope this helps. If you manage to access the Tech Rep mode, there is a button to press to reset the machine...

tha minolta di3510 developer unit looks the same as the unit for the konica minolta bizhub 350 but the toner sensor in the minolta unit uses a different voltage range for the toner sensor and it will throw this code make sure you have the correct unit for this machine also you can try this go back into tech rep mode and change these settings: select tech rep choice mode select printer tab select atdc sensor gain set the value to about 165 then back all the way out to the ready screen and power the machine off then back on and replenish toner in the user management screen.
Hi, C-12CB means you have a problem with a transfer of data from the Hard Drive. You may be able to format it somewhere in the Administrator settings. If not, a service engineer can Format the HDD in Tech Rep mode.
