I have some persistent deflected nozzles in the cyan and magenta channels in our 9900/Piezo Pro printer. The machine had the wiper blade and ink selector unit replaced in March and has been pretty trouble free until a few weeks ago. I’ve done several standard paired channel cleans, one powerful channel clean, and a cl3 for those channels, but can’t seem to fix it - there’s at least one or two line breaks in the nozzle pattern. On Friday I cleaned the capping station and wiper blade per the IJM cleaning video. This cleared things up temporarily in the magenta channel, but there was still a deflected nozzle in the cyan channel. I did a nozzle check this morning and am seeing deflections in the magenta channel again, along with issues in the cyan channel.
Any suggestions on what else to try? I can’t see air in the lines and the carts look primed.
