    There is no guarantee with any printhead once unpacked and fitted. This is why every step needs to be taken to insure no spikes when fitting them. Never had a failure yet, touch wood and never had a printhead fail to print after installation..28 dx4 heads fitted since end of covid lockdowns..

  14. head strike, what do i do now?

    That looks more like just blocked nozzles and not damage from a head strike. As others have stated, suck inks through to all dampers, do a head soak for a day and then run a hard clean a few times.. Do that and then do another test print and post it for us..

  18. Roland sp-300 looking for printing help.

    You need to spend more time cleaning the heads and only then do a complete calibration. Too many missing nozzles causing the banding.
  19. Roland sp-300 looking for printing help.

    Do your test in versaworks, alternatively go into the service mode menu, arrow down to test print, enter, arrow down to fill and print that pattern. Also a nozzle test print would be handy to verify the heads are ok.
