BH-C-284e C-4802

[Hansoon]

BH-C-284e coming from a wholesaler with C-4802.

Machine boots up normal showing all the usual shark fins and comes to a complete ready for a few seconds than C-4802 pops up.

What to do. Should I use any Voodoo tricks, sacrifice a cute fluffy animal for an obscure deity? Or just return the machine to its seller?

Perhaps any other better ideas or help, please?

No solution yet. This machine is bravely sitting in the warehouse since then. Now I would love to breathe new live into it.

NVRAM reset, or am I going in the wrong, even more destructive path with that?

Any solutions please?

Did you try and update the firmware? Are you able to get into service mode? I would try initialize there first. If that don't work I would use reset firmware.

looks like someone slapped a foreign board on it.

It's common on lease returns. All the parts appear to be there, but may not be the correct parts. Or you might find every consumable completely worn out.

What did you tried so far?
I guess we may throw some ideas but you really need to cover some basic stuff - firmware, service mode, clear all data?

6. Turn OFF the Main power switch, then remove the USB memory.
7. Turn ON the Main power switch; CD390 is indicated along with Japanese characters.
8. Let the machine reboot automatically two times.
9. After the 2nd reboot, code CD390 will display again, but now with English text, and a “Restore Data” button is also indicated on the panel.
Note: It may take up to 5 minutes before the English text appears.
10. Touch [Yes] on the restore screen to restore the data from SSDB to MFP board.
11. Turn the Main power switch OFF/ON.
Notes:
a. The original SSD board should have no problem and can be installed with the MFP board.
b.When replacing the MFP board with another one, never use the combination of a used MFP board removed from another machine and the original SSD board. This combination causes corruption of stored data. The combination of the original MFP board and a used SSD board removed from another machine also causes the same problem.

HOW TO REPLACE THE PRCB
IMPORTANT: Be sure the ORIGINAL PRCB is installed so that the data can be backed up BEFORE replacing the PRCB.
