Black ink has spaces in lines, color prints fine.
My Epson Stylus NX420 black ink has spaces (banding) in the lines when printed. I've replaced the cartridge 2 times, run multiple nozzle checks and head cleanings. It did not correct the problem. I also printed out a large .25" x 9" inch solid black box to find out what looks like on a larger scale. Here is a picture (or look below): http://bit.ly/2nGUwy0.
Someone said that a nozzle is clogged or not firing.
How do I fix &/or clean/unclog the nozzle.
Thank you for you help in advance!
