Thank you again. Would this premise apply to the entire row 2 blank on the test print? It started with just the yellow. We noticed many posts referencing the yellow ink not printing. Then after very careful cleaning, iall of the colors in row 2 were no longer displaying. I have always used OEM ink.This isn't for the faint of heart and will require a LOT of reading, but you might want to look at this (very long) thread. As I mentioned in my previous reply, I have seen ink congeal into a flexible glop, and over the years, I have seen this "glop" block the passages leading from the cart to the actual print head. I seem to remember that at one time yellow was especially susceptible to this problem. That is the background behind why I worked out a way to clean these passages. Be forewarned that these blockages can be terminal. I wouldn't even attempt to try these methods unless you have decided that the print head is toast and that you have nothing to lose. Also, read the entire thread to the end before starting because you can damage the ceramic print head if too much pressure is applied to it while it is attached to the black phenolic part. Good luck.
I‘m certainly up for doing the reading. Only thing is, I don’t know where the thread is located. Would you point me in the direction of the thread, please?
