Printer door open jam

If the top door is opened (this will activate the top door open switch; SW101) during a print operation, the microprocessor on the DC controller PCA determines there is door open jam.

The transport process is stopped and a 13.XX.YY JAM message appears on the control-panel display. For more information about jam messages, see “Alphabetical printer messages” on page 258 and “Numerical printer messages” on page 274.

Printer residual media jam

If either the top of the page sensor (PS103) or the fuser delivery sensor (PS108) does not detect the leading edge of the media at the start of initial rotation (see table 30 on page 67) the microprocessor on the DC controller PCA determines there is residual media jam.
