A:Answer I am not a computer guru and cannot advise on the settings, but would first suggest you make sure all your ink cartridges are full. If ink isn't the problem, you may want to check the source of your digital photo for resolution. Maybe try another photo to compare against the print job you are now trying to print? Sometimes I've found I can print one photo fine, but another just won't make the grade. It's usually due to the resolution of the picture, which depends on the sender or source of your digital file - or the software (e.g. JPEG vs. PNG vs TIF) (Google the three formats and maybe that will give you some guidance.) Sorry I don't have a whiz bang, easy solution, but I'm just not techie enough for much of these things. Especially when it comes to converting photos for print.
If there is a special settings "fix" on the actual Epson printer, I'm not aware of it, but like I said, I'm not a techie on these things. Good luck!
