I printed seven pages. My 4722 made printing noises. The paper came out with nothing on them. Got a message that the black cartridge was low. I replaced it. No improvement. The pages printed fine on my wife's Epson. Any ideas? Thanks.
Thanks to both of you. I'm an idiot. Got distracted. Didn't pull the protective tape off the cartridges. The 4722 is printing fine now. As a guy at work said years ago, "The problem is usually a loose nut on the keyboard". Thanks again.
