HP PSC 1610v All-in-One Printer - Manual (Page 95)

I received a message on the control panel display to attach the control panel
overlay
Solution This might mean the control panel overlay is not attached, or it is
attached incorrectly. Make sure to align the overlay over the buttons on the top of
the HP All-in-One and snap it firmly into place.
