I just received a new flush kit for Epson 4900’s and I’ve run into a problem with one of the refillable cartridges. I’ve prepared and installed several of the cartridges per the instructions with no problems. When I install the LK cartridge, all of the cartridges on that side for the printer pop up with the x in a red circle error. When I switch the refillable cartridge out for the Epson LK cartridge, everything goes back to normal. Could it be that I have a bad chip?
