If so, I fear that repair costs will be more than a new printer.
My Brother mfc 255cw don't print black only other colors, while ink level almost full. Using cleaning in the menu take too much ink so I injected alcohol into the black head almost 30ml, I don't know where the alcohol goes, because I just see a little came out under the printer, searching on the web I found many solutions but does not meet the problem I met. All other color are compatible but print out real good in test prints, while the black is Brother brand cost much more than others. Will someone show me how to get the black ink back.
