Smart Tank 651 only prints in red when using glass top but prints in black from computer.

HP Smart Tank Plus 651 - When printing from glass top or document feed it only prints in red even though I hit Black. But printing from a computer it prints in black. Full HP ink tanks, cleaned and aligned the heads, set Factory defaults - it still prints in red when using the glass top. The manual does not address this. Any ideas out there??

Thank you sir much for your detailed response - but it didn't work. What I DID find out is that the color sensor is no longer working. I kept checking the ink levels through the computer and printer screen. It consistently said all ink cells were full. I finally visually looked at the ink cells and they were all very low. I filled each one and tried to copy a color printed document. All of the black letters and lines came out red, green came out yellow. So the color sensor is bad. Time for a new printer.
