Review on Intactech Compatible Ink Cartridges: Brother LC-3011 LC3011 BKCMY Replacement for Printer MFC-J491DW, MFC-J497DW, MFC-J690DW, MFC-J895DW - 3 Sets-12 Pack (3 Black, 3 Cyan, 3 Magenta, 3 Yellow) by Nicholas Peters

Bought a Brother MFC-J497dw printer and these spare cartridges in case they run out. At one point I ran out of the original ink that came with my printer and tried to replace it with this one. I get question marks about the machine running out of ink which I've tried taking out and putting back in many times and still nothing. Even tried another and nothing. I'm not allowed to print everything now. Big waste of money!
