How can I fix my Epson Stylus CX5400 printer?

My printer will only print bright pink when copying a picture. It will not print black when printing from the computer. Do you have any suggestions??? My Epson is NOT printing black ink. I’ve done all of the maintenance things: nozzle check; head cleaning; print head alignment, etc. SEVERAL times. It also will not copy in black (so I feel it is a printer problem and not a computer problem). I have replaced the black cartridge this a.m. even though my old cartridge was over half full and still no luck. Unfortunately, it is a couple of years old so I don’t have any service warranty on it. This is an Epson Stylus CX5400 printer.
