MK ink not working

mk ink not working , i used the piezo flush , not working

Please let me know a few more details.

Is this with your R3000? If so, is what was in there before the PF? Our ink/cartridge or Epson?

How long has this printer sat before attempting to fix with PF?

Are you able to switch to PK, do a cleaning, and get any nozzles printing?

All of these help me determine what is going on with your printer.

All the best,
