7.2 Detecting and Clearing Jams
Jams are detected by the paper pickup (PS13) and fixing unit exit (PS12)
sensors. The DC control board examines the sensors as the sheet proceeds
through the paper path. If the sheet fails to arrive under a sensor or remains
under the sensor too long, the DC control board stops the main motor, shuts
down the fixing heater, and sends the error to the video control board. The 13
PAPER JAM message is then displayed by the video control board.
FIP Note: Section 1.3.1 and Section 1.3.2 describe the paper path and
components of the paper path. Figure 1–7 shows where PS12 and PS13 can be
found.
