If the fuser delivery sensor (PS108) does not detect the trailing edge of the media within a specified
period of time after a printer delivery wrap jam is detected, or if the fuser delivery sensor (PS108)
does not detect the trailing edge of the media within a specified period of time after it has detected
the leading edge of the media, the microprocessor on the dc controller PCA determines that a printer
delivery wrap jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages or Numerical printer
messages.
Printer delivery-delay jams
If the fuser delivery sensor (PS108) does not detect the trailing edge of the media within a specified
period of time after detecting the leading edge of the media, the microprocessor on the dc controller
PCA determines that a fuser stationary jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages or Numerical printer
messages.
If the fuser delivery sensor (PS108) detects the trailing edge (paper out) of the media within a
specified period of time after it has detected the leading edge of the media, the microprocessor on
the dc controller PCA determines that a delivery jam has occurred.
However, if the paper-length that the top-of-page sensor (PS103) detects does not match the media
size that the printer expects from the pickup source, this jam is ignored. The top-of-page sensor
(PS103) determines the length of the page by measuring the time it takes between when the leading
and trailing edges of the page pass the sensor.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages or Numerical printer
messages.
NOTE This jam cannot be detected for pages that are less than 200 mm (7.9 inches) in
length.
Printer door-open jam
If the top door is opened during printing, the top-door-open switch (SW101) is activated and the
microprocessor on the dc controller PCA determines that a door-open jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages or Numerical printer
messages.
Printer residual-media jam
If neither the top-of-page sensor (PS103) nor the fuser-delivery sensor (PS108) detects the leading
edge of the media at the start of initial rotation (see
Table 5-1 Basic printer operating sequence), the
microprocessor on the dc controller PCA identifies a residual-media jam.
