I have a P6000 and Pro Ink Set on Windows 11. I’m getting micro horizontal lines. I flipped the Y and LLK channels to solve the issue but that did not work. I’m also getting missing dots in the VM channel. I took the ink selector off and cleaned the unit, also flushed the print head. Still getting micro horizontal lines. I ran the nozzle check in the service program with the small, medium and large dots, there was little to no missing dots. But when I ran the nozzle check from the printer panel there are dots missing when viewed with a loupe. I’ve acquired a Mac Pro Notebook to try the Piezography Driver and a new Ink selector and cleaning unit at a great price.
Any ideas why the Service Program nozzle check looks good but the printer panel nozzle check has dots missing.
