Solution for konica minolta 250 malfuncion detected c2557

What is error code c2557 on Konica c220?

Check the toner bottle to ensure that it is feeding toner into the sub hopper unit under the bottle. Sometimes users will insert the bottle incorrectly and not lock it properly in place...the lever on the front of the toner hopper for that bottle is moved down to the left to remove and insert the bottle.

Hello,
C2557 - Abnormally toner detected black tcr sensor.

Reinstall image unit black
Reinstall toner cartridge
Change Image unit
Change toner carridge.

Reset it, start it with the right door open, go to service mode, clear the counters for drum and developer and go to functions menu. Close the right door and start immediately the F8 function. It should work.

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.

Tell me if you need to execute it.
