Szilard Posted November 10, 2023 Share Posted November 10, 2023 We bought 3 months ago this printer everything went fine untill now , recently we changed the ink pump assy ( the whole capping station ) after that everything went fine again until i changed the dampers , my white wont want to print , the head is 100% not blocked because after ink charges the whites come back but after a half a3 sheet the white will be dosappear again , we changed back the old dampers but still same issue , the colors on nozzle check is 100% so i dont think its a capping station problem , but i dont know what can be the problem any ideas ?

Sounds like you changed the dampers too late and sucked white ink sludge into the printhead. It’s not easy to fully remove. It causes the exact issues you describe.
