I have an Epson WF2750 and I love it. My original problem was the black would not print even though I put in a new cartridge. I did a search on google and they came up with printing using glossy setting on both the computer and printer. This did work however, it took a long time to print and my husband hated it. He wanted to buy a new printer. I did some more searches and found several Youtube videos on how to clean the print heads. Well I tried it and I have my old printer back. Everything works.
I used a solution of windex and rubbing alcohol, a syringe, and a 1 inch piece of tubing like for an aquarium tank. I followed the videos, turned off the machine heated the solution in the syringe and put it over the print head and injected the solution. I did it a couple of times (3) on each head until there was no more color coming out. I turned on the machine, loaded the ink, did a head cleaning and voila, it works. I am so proud of myself. I wasn't looking forward to getting a new printer just yet as I have a supply of ink that would have gone to waste.
