So I have a 3880 which I charged with fresh cartridges filled with Pizeoflush. Made an initial fill charge with adjustment program, waited 48hrs, did another one, and the LC was still 100% clogged.
Every nozzle is perfect and prints pink except LC. Nothing prints at all for LC.
Waited another 24 hours, to give Piezoflush time to dissolve more, then did the Nozzle check/print image/nozzle check/print image thing as I read about it on luminous-landscape, and the 3rd nozzle check started printing some pattern, and it was still blue! I can’t believe that after TWO initial charge there would still be blue ink left. So I’m thinking the damper must be totally blocked or 98% blocked, making it impossible for Piezoflush to reach the tubes and the head.
My concern is if I try changing the whole ink selector unit (eBay has individual dampers available but the service manual has no instruction on how to replace individual dampers) but the print head is the problem? It’d would suck to put $200 on a part + my time to change something for nothing. I may as well change the capping station at that point. If I have to change the printhead too then its no longer a cost effective operation.
