Because the PK/MK channel in my 9800 is terminally clogged I have converted it to a GO printer only. I have installed a new cartridge with GO in slot LLK and PiezoFlush in all other channels. Using QRTGui I have selected print model Quad9800-K7 and curve 3500GO_distributed_x800. When I test print I get full page of PiezoFlush.
Please advise what is wrong.
