I am using your refillable all black screen print ink system. I recently unplugged my printer power and usb cables to rewire the office. When I powered the printer back up 3 cartridges are not being recognized. These cartridges have the new style chip that can’t be reset. I have tried removing all cartridges right to left, powering off the printer, unplugging the printer, pressing the power button to clear any memory, waiting a minute, powering the printer back up, and inserting the cartridges left to right. The same 3 cartridges are unrecognized. They all have plenty of ink. The cartridges are LLK, Y, and VLM.
Please help. Thank you.
