The printing device according to one embodiment includes a chassis substantially housing a sheet feeder, a sheet conveyor, and a print applicator; a microphone externally mounted to the chassis for converting audio signals sensed by the microphone external to the printing device to a raw analog electrical signal; an analog low-pass filter for filtering out high frequency harmonics from the raw analog electrical signal to result in a filtered electrical signal; a controller comprising an analog-to-digital port, a processor, and a memory. The controller receives the filtered electrical signal at the analog-to-digital port and samples the filtered electrical signal at a sample rate of at least twice a bandwidth of the filtered analog electrical signal to result in a sampled signal clip. The controller determines a time duration of a portion of the sampled signal clip associated with a print cycle event. The controller stores in the memory data associated with the sampled signal clip for comparison with a training signal clip associated with the print cycle event."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Printer diagnostics using external microphone","description":"The present disclosure is directed to a printing device, a system, and a method.
