Hi, I purchased the magenta cartridge with piezo flush for my 7900, did the initial charge and did a nozzle check (someone I spoke with at IM advised that) and saw that the display was similar to the magenta, but a bit lighter. No difference after 48 hours. After a bunch of regular cleanings with a teeny change that can only be seen under a magnifying glass, I did a sonic cleaning and now the nozzle check shows a much lighter display, but no added lines. I am letting it sit for another 48 hours as maybe the flush didn’t originally get to the head. The nozzle display is extremely light.
What should the next step be?
All this happened after I tried the windex paper towel cleaning. Before that the magenta was fine; I was trying to fix the yellow. The magenta nozzle check now shows 2 large sections of lines missing near the middle.
Another question- I have orders for b&W prints. Can I print them with the flush in the magenta as maybe the advanced B&W only uses the 3 blacks?
