is there a way to put dx7 dampers to the head connected to ink bottles with completely removing the hole ink bay? i would like to know for a P600I was replying to a specific question
"If we use dx4 dumper instead of ink cartridges..."
But if you decide to switch with DX7 dampers for printhead, you only have to modify the ink tube, from the ink bay assembly exit to the print head, but you still use the original ink bay.
So yes there is still an ink pressurization system in place.
