I've got a 2230d with LEDs Toner and Error on SOLID. Indicates "Cartridge Region Mismatch" I confirmed printer is in fact region 1 (America) and I tried a genuine Lexmark plus three known good compatibles. All give the same error. I tried replacing the drum, same error. I tried each cartridge from a power off start and the door open reset each time. Error will not clear. Is there another component that can cause this?
