I ran a nozzle check on my 4880 this morning after three days out, and it showed a blocked nozzle (LLK) and some gaps, so I ran a cleaning cycle. Still showed some gaps, so ran a second cleaning cycle, and then a power clean when I still had some gaps.
After the power clean, the nozzle check showed this:

I ran through the cleaning process that IJM recommends (paper towels, PiezoFlush, etc), with no apparent change to nozzle check.
Anybody have any guesses as to what may have caused this, and if it’s something I can fix? Or do I need a new printhead?
