Ink cartridges stop working. I opened the printer, shook the cartridges and heard they still had ink, but now the Epson WF4734 printer reported that it didn't recognize the codes on the cartridges. It didn't happen when I installed the replacement ink. The code recognition was probably activated during the firmware update. Until Tieno fixes this problem. I couldn't recommend buying these replacement cartridges more!
