First Tip, don’t buy an epson workforce 7010, it is user unfriendly, refilling inks is a pain and probably won’t work as well. This printer never did print blacks well. It only has 4 colors. I wasted $250. Now that I have the canon pro100, my epson prints are not near as good. I have about 150 prints now and refilled all the cartridges at least once, but did get about 100 before I needed to start refilling. Follow instructions carefully, and watch videos online.
Refillable inks can only be bought from precision inks.com. I bought them and refilling went ok and prints look just as good.
Don’t buy blank cartridges, the chip won’t work so I wasted $60 to find that out. Instead, buy one set of new canon ink cartridges for $120, and you’ll have the second set that you need.
If you use hp glossy paper, it takes a long time for ink to dry. They won;t go into a plastic sleeve until they dry for about 30 minutes.
