Working fine today. Then out of the blue, it doesn't recognize the black cartridge. Dell Photo AIO printer 944 "Printer cartridge missing". Took the cartridge out/reinstalled, nothing. Cleaned the area of the black cartridge nothing. Shut the printer off, nothing. It shows a ? mark on the black cartridge icon...... What to do?
