I have an Epson7600 which I have just changed over the Epson Color inks to VPneutral shade inks. I did a Flush with the Piezo fluid before filling with Neutral Ink.Let it sit overnight and then did a second PFlush the next morning. Prior to the ink change over, my color prints were fine (done on same day). After I flushed out the system, I could not get any nozzles to printout on the nozzle check.
I “Initial filled” the system and cleaned the heads (via printer). Tried a nozzle check and got nothing once again. By nothing I mean not one drop of ink on the sheet.
I have since tried the following to no avail: A number of “power” cleans as per your printed instructions with inks. Cleaned the reservoirs and cap station as per your online video. Cleaned the heads. Let the heads soak overnight with paper towel soaked in PFFluid. There are no visible clues to follow regarding the LCD panel on the printer, as all looks normal and no error lights come on.
As mentioned above, I was printing in color earlier in the day of the change over and the print quality was excellent. Your thoughts and suggestions would be helpful. Thank you.
