Printer delivery wrap jam when feeding regular media
Regular size media is defined as A4, letter, legal, B5, executive or A5.
If the fuser delivery sensor (PS108) does not detect the trailing edge of the media after a
specified fusing time the microprocessor on the DC controller PCA determines there is a fuser
wrap 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 delivery wrap jam when feeding non-regular media
Non-regular media is defined as media that is less than 200mm (7.9 inches) in length.
If the fuser delivery sensor (PS108) does not detect the trailing edge of the media within a
specified time after a fuser wrapping jam is detected, the microprocessor on the DC controller
PCA determines there is a fuser wrap jam.
Or If the fuser delivery sensor (PS108) does not detect the trailing edge of the media within a
specified time after it has detected the leading edge of the media the microprocessor on the DC
controller PCA determines there is a fuser wrap 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 delivery delay jam
If the fuser delivery sensor (PS108) does not detect the trailing edge of the media within a
specific time after detecting the leading edge of the media, the microprocessor on the DC
controller PCA determines there is a fuser stationary 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.
If the fuser delivery sensor (PS108) detects the trailing edge (paper out) of the media within a
specified time, after it has detected the leading edge of the media the microprocessor on the DC
controller PCA determines there is a delivery jam.
However, if the paper length detected by the top of page sensor (PS103) 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 tim it takes between the
passing of the leading and trailing edges of the page.
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.
Note This jam cannot be detected for pages that are less than 200mm (7.9 inches) in length.
