Minolta Chip error code C-2551


Minolta C552 customer said that there is a problem with the drum rack, error code C-2551?


This C-2551 is a machine that detects that the toner concentration is too low. Solution: When the machine prompts the code, open the front cover, then close it, let the machine run, then turn it on again, then turn it off, and the machine will run again. This is repeated several times until the code disappears. This is a problem with powder supply. The machine detects that the concentration of toner reaching the developing chamber is too low, meaning that the powder is too small. I let the front cover switch several times. Let the machine run on its own, it will supply powder, and the code will disappear.
