6.8.4 PAPER JAM, TRAILING EDGE DETECTION
The feeler [1] is pushed down by every sheet of paper that arrives and then pops up again
when the trailing edge of the sheet passes over the feeler. When the paper presses down
the feeler, this turns on the trailing edge sensor [2]. The length of time the trailing edge
sensor remains on is used to measure the length of the paper for printing control.
A paper jam alert occurs when:
 The paper feed roller rotates forward twice.
 The trailing edge sensor does not go on after 2 rotations of the paper feed roller.
