Epson R2880 with Piezo inks for Digital Negatives.
When I made the conversion from Epson Inks to Piezo inks last month, everything went exactly as expected. Ink was flowing, no problems. All of a sudden, my Nozzle Check (attached scan) shows two positions with huge gaps in the lines. I ran several head cleanings via the Epson Printer Utility - no change. I took out all the carts and cleaned the wiper blade, print heads, and capping station precisely as shown on the Piezo video (the same process I did when I first set up the printer and it worked fine), ran a few more head cleanings - [I]and the nozzle check is exactly the same. [/I]
Jon referred me here… any suggestions? I’ve done all that I can do according to the existing Piezo documentation.
