F26 Toner density adjustment problem. This means machine is undertoned. To repair, replace developer and enter "47" mode. Press 51. Press print. Allow the machine to cycle until it stops. Some feel that you should disconnect the toner motor first. This ??? ?????? happens probably because either machine wasn't set up properly, or the customer kept on using the machine with the toner light on.

There is not a C0876 listed in the service manual. Perhaps it's a C0B76 - Finishing option Punch Unit Board Malfunction.
CAUSE: The shaft on which the gear rides is deformed. The punch unit cannot be driven from front to rear.
SOLUTION: Reform the shaft toward the punch unit rail. This will allow the drive gears to mesh properly so the punch unit can be mechanically driven from front to rear.

C400 is exposure lamp fails to come on, on start up the main exposure lamp should come on and do a scan.
If the lamp is not detected by the sensor, then you get the code.
Restart the machine, watch for the exposure lamp. if it does not come on before the code occurs, then the lamp or thermal fuse is likely gone.
if the lamp comes on then the code, the AE sensor is likely gone.
Hope this is of some help.

Since you did not include the Model number I will suggest the following:
This code means pretty much the same on all Konica/Minolta machines.
The ATDC or automatic toner density control has experianced a problem. Have you run the copier out of toner by chance?
You can try resetting this code to see if it comes back. If it keeps coming back then you are going to need the process unit serviced. Or depending on the model you can replace the "Imaging Unit" yourself.
