Epson Epson Stylus Color 3000

Epson Stylus R 3000

The printer worked fine until I replaced the black ink cartridge. Now it won't print black. It's a genuine Epson cartridge and is recognized by the printer and no error messages show. The local Epson Express center have run their diagnostic software and failed to find a solution. For some reason, they didn't open the printer up to investigate.
Since the cartridges are fixed and don't move when printing, could it be the connection to the print head?
