I have an Epson r2880 that is configured to automatically print two nozzle checks per day, 12 hours apart. Last evening's nozzle check was perfect but this morning's nozzle check showed a mostly empty band 1/8" high cutting horizontally through all 8 colors. I did a head cleaning and the band remained but all the lines of my LM 90% disappeared. I let it sit for a few hours and did another head cleaning and the LM came back (still with the 1/8" band) but now my LLK completely disappeared. Never encountered anything like this before. All inks are 1/2 or more full. All ideas welcome. Thanks. (Is it possible to upload a picture of the printout?)
