Abstract
A system for detecting friction between an object, that is being printed in a printer, and a print head moving relative to the object, comprising: an acoustic sensor system arranged to detect an acoustic noise signal generated by the printer; a recording system arranged to record the noise signal while the print head moves relative to the object; and an electronic processing system arranged to detect, in the recorded noise signal, correlated with the reciprocating movement of the printhead over the printed object, a signature that is characteristic of an event of friction between the print head and the object.
