Fuser-delivery delay jam
If the fuser-delivery sensor (PS108) does not detect the leading edge of the media within a specific
period of time after the top-of-page sensor (PS103) detects the leading edge, the microprocessor on
the DC controller PCA determines that a fuser-delivery delay jam has occurred. The time varies
according to the length of the media.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Fuser wrapping jam
If the fuser-delivery sensor (PS108) does not detect the trailing edge of the media within a specific
period of time after it detects the leading edge, the microprocessor on the DC controller PCA detects
that a fuser wrapping jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Fuser-delivery stationary jam when feeding regular-size media
NOTE 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 within a specific
time period after it detects a fuser wrapping jam, the microprocessor on the DC controller PCA
detects that a fuser-delivery stationary jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Fuser-delivery stationary jam when feeding custom-size media
If the fuser-delivery sensor (PS108) does not detect the trailing edge of the media within a specific
time period after it detects a fuser wrapping jam, the microprocessor on the DC controller PCA
detects that a fuser-delivery stationary jam has occurred.
NOTE The time period varies according to the length of the media. The interval is longer for
media that is 200 mm (7.9 inches) or longer.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Reversing delay jam (face-down delivery only)
If the reversing-paper sensor (PS110) does not detect the leading edge of the media within a specific
time period after the fuser-delivery sensor (PS108) detects the leading edge, the microprocessor on
the DC controller PCA detects that a reversing delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Reversing stationary jam (face-down delivery only)
If the reversing-paper sensor (PS110) does not detect the trailing edge of the media within a specific
time period after the fuser-delivery sensor (PS108) detects the trailing edge, the microprocessor on
the DC controller PCA detects that a reversing delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
