I purchased this Refillable Cart for the PK position with Pieso Flush to solve a clog issue in my PK ink several months ago. It worked great. I got a sudden and complete clog in PK while printing today. It literally went from printing fine to completely clogged halfway thru a solid black print. After running a cleaning cycle via the service program, which did nothing, I went to try to do a flush again. Second time using the cart, and the printer isn’t picking it up at all - just the (X). I know the batteries an die on the chips, but this one has hardly been used and is less than a year old. Any advice to get it reading ? Should I request a replacement for the seemingly faulty cartridge? Additionally Ill gladly take any advice on the clog, its really screwed up my day I have a ton of work to do. Thanks!
