HP Photosmart C5550 All-in-One Printer, Scanner, Copier. Error message "Cartridge in slot on right is not intended for use in t his printer. Remove and replace." This cartridge has been in the printer for a week and has been used without difficulty. It is the correct cartridge. I have removed it and put it back in, but still get the same message.
