If media does not reach or pass each sensor within a specified time period, the DC controller determines that a jam has occurred and - HP LaserJet M2727 | Service Manual - Page 100
NOTE: This sensor has two sensor flags; one flag detects the media when it is delivered from the fuser, and the other flag detects the media when it is reversed for duplexing.
