Review on Do it Wiser Printer Toner Cartridge Replacement for Brother TN227 TN227bk TN223bk TN223 - MFC-L3750CDW HL-L3210CW HL-L3290CD HL-L3230CDW Printer - 4 Pack by Julius Lito

These are supposed to be compatible toners - they fit the machine but the end result is totally unacceptable. I wish I had tried them as soon as I got them. Now I'm forced to use until I can get a QUALITY toner. Very disappointed. The attached image must be an unprintable white area. These shadows and lines appear on every page no matter what is printed. Absolutely unacceptable. Before replacing the toner, the print was fine.
