After switching my P6000 over from color to Piezo Pro inks using the SC-P6000 Service Program (PC) it is embarassingly obvious I rushed into trying to linearize my printer. I noticed a strong greenish cast in the mid-tones of each printed target. I should have stopped and done another head cleaning. I finally asked for help (I wish I had much sooner!). Walker recommended running an ink channel validation using “QTR-Calibration-Mode.”
When I ran the ink channel validation the 5 rows at the bottom reveal the cyan, magenta & yellow ink dampers are still contaminated with color pigment. Another clue was “a” & “b” values measured by my i1Pro 2 spectrophotometer indicated color, which gray & black inks don’t have!
Should I hook the P6000 back up to my pc and run 1 more “Ink charge”? Then repeat the Ink Channel Validation again to look for color pigment in my Epson’s ink dampers?
