This sample is a recording of a HP Deskjet 722c inkjet printer as the
front cover is lifted and replaced. The printer uses a number of
high-pitched motors removing
a cover from the print head, then another lower-pitched motor to move
the print head to the center of the. After the cover is lowered, the process is replaced, moving the print head back to where it is parked when not printing, and replacing the print head cover.
Recorded into an AC'97 soundcard with a generic microphone, then processed with a high pass filter and noise removal in Audacity.
