Hey all, I want to know that why does my printer uses color ink when I try print black and white? I had to replace the color cartridges even though only print black and white. I can print black and white for a time after receiving a message to replace a color cartridge, but eventually the error will not go away and the printer will not work to replace one of the color cartridges. Please help me in this case. And also reply me if anyone having the same problem.
