I have a 7900 with an imperfect LC nozzle that I cannot unclog. Is it possible to use the printer for piezography using an alternative position for the ink that would be in the LC position?
Yes, absolutely!! Are the other channels working well? If so, you can modify the shade placement and curves to use shade 3 in the orange or green position, and install PiezoFlush in the LC channel to make good use of this printer for Piezography printing.
