HP Deskjet 3070A All in One Printer
This is around 9 years old, it was only used for one year at university and has been stored away ever since. It powers up ok, paper feeds through ok, looks like the black ink cartridge has dried up as I have printed test sheets with the six colours on it fine and copied a document in colour fine, but when I try to print, or copy using black and white, the paper just continually feeds through until I switch printer off. The black ink cartridge will need replacing and hopefully all should be fine, but I don't know.
