    Yellow and magenta are on the same head and protected by the same fuse. If they just dropped out completely out of the blue, that's probably the issue. Check your head cables to make sure they aren't dirty or damaged. If they are, replace them. Then replace the fuse. It's a 1.6 amp fuse and, depending on the age of the machine, it's user replaceable but might need to be soldered if it's an older version.

    Please attach a nozzle test print. If you have absolutely nothing on the magenta/yellow head, as said by solventinkjet, then a blown fuse for sure. Besides the cables, it could be a shorted transistor on the head board or a bad head. Did anything happen before the channel loss, such as a head strike? If you know how to use a resistance meter, I can guide you through checking the fuses and transistors.

    Did it happen overnight? If so it could be your capping station. If it happened during the day after a successful print try the fuse.

    Try to do powerful cleaning and test print, if nothing happens, it will require technical maintenance

    Take the cover off the capping station
    Park the heads on the caps
    Pull the line coming from the caps to the pump
    Apply suction to that line with a syringe until you see ink
    Do a test print
