Re: Calibration print banding -- Epson 3800 fixable?

If the nozzle check seems to be good on all but three LM nozzles, but you're getting banding on some other channels in a QTR calibration / ink separation print, then I wonder if there are misfiring nozzles in those other channels, esp if the printer has been left idle with old inks:

To pick this, you usually have to examine your nozzle pattern under a loupe.
