Hi SteveH. Yes, Epson printers, including the WorkForce Pro WF-4820, contain a permanent print head that needs to be charged with all colors to work. Even when you are printing black text only, a small amount of color ink is used to keep the print head charged, preventing air bubbles from entering. Air bubbles can damage the print head.

Sorry, there was a problem. Please try again later.Unsure. I would think that you should be able to set the printer to use black only whenever you like. Check in your settings under your printer to see if possibly you can change it to black only when needed. This probably would be a very good question for the geek team.
