Hello! We purchased the Piezoflush cartridges for our Epson 9900 to try and clear some stubborn clogs in our O, Y, & VM. We have run 2 initial fill cycles with several regular cleaning cycles (and a few power cleaning) in between and I’m not yet seeing any progress. I’m still seeing orange, yellow, & magenta ink printing on the nozzle checks (although very lightly) and the clogs are still apparent on the nozzle checks. How many initial fill cycles do I need to run before I start seeing pink staining on my nozzle checks? Would it help to run a test print maybe to move more PiezoFlush into the printhead? I have been following all instructions and letting the fluid sit in the lines for 48 hrs between fills. I’ve also scoured the forums for information on what to expect and I’m coming up empty. Any tips, help, or insight?
