Hello all just got a GS6000 only issue was orange channel is gone. When printing the nozzle check I get nothing on the orange channel on A or B. I cant see any airbubbles in lines, cartridge is almost full (80%). Cant seem to find a rhyme or reason as to why its out? This is our first Eco-Solvent printer and happy so far but would really love to have the ability to print that missing channel.
