Is the reset software required after replacing the dampers? Somewhere here on the forums I read that 3 Power Cleaning cycles are equivalent.
I suggest an InitFill from the software personal-opinion but it won’t hurt to do a few power cleanings . . . If you have reset the damper you may need the software to also do slant alignments of the printhead though . . . so it might be worth it to go ahead and get the software at 2manuals to be safe.
