I have Canon printer LBP623Cdw and i want to refill it with powder ink Only the black color
so it was telling me that the balck color is need to be changed and is not more printing in this color
I brought powder ink that is only the black one and filled all the cartridges almost and when i settled down in the printer and i pressed the printer to the status of filling, i got the same thing, the black color is still zero despite I filled it completely. It can printe in that color but still giving me warning that the black color is finished. I don’t know what’s wrong?
note: the cartridges not replaced meaning that the same cartridges that came with printer that is original.
please help me
