Delivery delay jam during face-down delivery
If the paper-delivery sensor (PS109) does not detect the leading edge of the media within a specific
time period after the paper-reversing operation starts, the microprocessor on the DC controller PCA
detects that a delivery delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Delivery delay jam during face-up delivery
If the paper-delivery sensor (PS109) 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 delivery delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Delivery stationary jam during face-down delivery
If the paper-delivery sensor (PS109) does not detect the leading edge of the media within a specific
time period after the reversing-separation solenoid (SL106) is turned off, the microprocessor on the
DC controller PCA detects that a delivery delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Delivery stationary jam during face-up delivery
If the paper-delivery sensor (PS109) 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 delivery delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Door-open jam
If the top door is opened during printing, the top-cover 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.
Residual-media jam
If the top-of-page sensor (PS103), the fuser-delivery sensor (PS108), or the reversing-unit jam
sensor (PS111) detects the leading edge of the media at the start of initial rotation, the
microprocessor on the DC controller PCA identifies a residual-media jam.
In addition, if the fuser-delivery sensor (PS108) does not detect the leading edge of the media, within
2.1 seconds after the top-of-page sensor (PS103) detects the leading edge, the microprocessor on
the DC controller PCA identifies a residual-media jam.
Whenever the MFP is turned on or a print sequence begins, if the pre-feed sensor (PS102) detects
the presence of media, an automatic-delivery request is sent to the formatter. The DC controller PCA
drives each motor, and the residual media is delivered to the output bin. Normal printing can continue.
