Abstract: A print head protection system is used in connection with an inkjet printer having a print head adapted for elevating, and a belt moving over a platen. A plurality of acoustic sensors is arrayed transversely to the process direction. The acoustic sensors measure a combined thickness of the belt, the platen, and the media sheet. An analyzer will detect if the media sheet is in contact with the media transport. An error signal is created when the thickness is below a predetermined value, indicating the media sheet is not in contact with the media transport. A mitigation control is operative to mitigate print head damage in response to the signal. Printing is halted in response to the signal to preclude damage to the print head. The sheet is discarded.
