Yesterday Nozzle check show the lack 50 % of nozzle field, and today without any cleaning print head the nozzle condition is better.Firmware is new from Epson site.I tried program SC-T series for cap position adjustment,but same problem. I cleaned the print head but the failure is repeated after a couple of days of use.
