9600 no ink to head

I’m trying to get a 9600 going. It has a relatively new OEM head. I have PeizoFlush in all the lines but I can’t get it into the head. I have tried several pumps to no avail. I have tried to draw it into each damper. Some hold it and some have bubbles in the line. at any rate the fluid does not reach the head. what, in order of likelihood, would be the probable causes. The dampers are pretty new and have had peizoflush only.


I’m trying to clean up an older head. There are blobs of ink on the face of the head that have not dissolved over 2 weeks of soaking in peizoflush. can I wipe the face of the head with something. Or is there a stronger solution I can soak it in?
