The device determines if a jam has occurred by determining whether paper is present at the sensor or not at a specified time in the printing process. The printing process timing is stored in the device memory. If the device determines that a jam has occurred, it stops the printing operation and produces a control- panel error message. The table below describes the two different types of jams.
