My humidity hovers around 50% right now and I rarely have head cleanings, except for the yellow channel. I usually print a nozzle check before a print job, and every time, the yellow channel needs cleaning. In the last month, none of the other channels indicated a cleaning was needed. Is there something 'different' with the yellow? I remember reading somewhere that it's the weakest of the colours - but doubt that has anything to do with it.
Is this something I should be concerned about that I should get looked at while it's still under warranty?
