Review on DOUBLE Replacement MFC J6945DW MFC J5845DW Lc3037 by Punk Espinoza

My brother MFC-J6945DW does not recognize these cartridges. I was told to replace them all with new ones (seems like a waste of time, why would I change everything to one that is blank but oh well). It still won't work. Don't waste time. Addendum: Good customer service. They contacted and offered a refund or replacement. If I have the opportunity to try a product to see if it works, would I say try it? Maybe you have better luck.
