The bottom line is that I have used almost a full bottle of PiezoFlush trying to get a good nozzle check on a new Epson P400 printer and I don’t know what to do next. Please advise.
I have a month-old Epson P400. It is my first printer and this is the first time I will be using piezography ink.
After setting up the printer I ran nozzle checks every few days with the Epson inks and always got perfect results. The last nozzle check with Epson inks was yesterday, and it was perfect.
Today I replaced my Epson cartridges with brand new IJM cartridges which I had filled with PiezoFlush following your directions. I ran three head cleaning cycles spaced ten minutes apart followed by a nozzle check. The Yellow channel had five dashes missing, so I ran additional cleaning cycles and nozzle checks. I was able to get the number of missing dashes on the yellow channel down to three:

but I can’t improve beyond that.
I used a LOT of PiezoFlush just getting to this point. In fact, the printer is giving me the “Time to Buy More Ink” popup! I’ve used up nearly a whole bottle of piezoFlush!
It’s hard to believe that the yellow channel is plugged because I was getting good nozzle checks with the Epson inks as late as yesterday.
I have a PiezoFlush kit and I would have used it. However the dummy cartridge does not fit the P400, so that’s not an option.
FYI, my reason for replacing the Epson carts with PiezoFlush carts was that I wanted to make sure the PiezoFlush carts were working (and primed if needed). Once this was done, I was going to replace the piezoFlush carts with piezography carts. I’m glad I did it this way because I would have wasted $400 worth of ink on all those cleanings and nozzle checks! I won’t install the piezography carts until the issue with the yellow channel is resolved.
What should I do next?![]()
