Jam Code

Jam Type

Type
Delay
A delay jam occurs when a sensor was not turned
ON although a specified period of time had passed
after the start of detection by the sensor.
Stationary
A stationary jam occurs when a sensor was not
turned OFF although a specified period of time had
passed after the sensor was turned ON.
Door open
A door open jam occurs when a sensor detected
door open during printing operation.
Sequence
A sequence jam occurs when there was an error in
sensor detection signal at printing operation se-
quence.
Since the jam may occur due to sporadic noise with
software of each equipment or communication line
(interruption of communication), failure of the part
is not the cause of the jam. After the jam is removed,
the machine works.
Power-on
A power-on jam occurs when a sensor detected ON
state at power-on.
Error avoidance An error avoidance jam occurs when an error in the
machine (excluding parts failure) was detected.
Printing operation is suspended to avoid error oc-
currence by error code; therefore, parts failure is not
the cause of the jam.
After the jam is removed, the machine works.
If it is due to parts failure, an error code instead of
the error avoidance jam is displayed on UI and
printing operation is suspended. In such case, serv-
ice technician should perform remedial work for the
error code.
Size error
A size error jam occurs when the difference be-
tween the paper length detected by the Cassette
Guide Plate/specified on the Control Panel and the
length measured by the Registration Sensor is out
of the specified range.
Forcible stop of
It occurs when a sheet of paper stops at the position
paper feed
specified in service mode.

Jam screen display specification

Due to one jam code being used for multiple options, the illustration for the different option may be displayed on the jam screen.
In this case, "1/2" or similar information is displayed on top left side of the screen and this area can be pushed. This operation
can be used to switch information on the screen.
Overview of detection
Check items (in arbitrary order)
• Remaining paper at the upstream of the target sensor
• Soiling on the target sensor
• Displacement of the target sensor position
• Failure of the target sensor
• Soiling (grease)/deterioration/failure of a drive motor located
upstream of the target sensor
• Soiling (paper dust)/deterioration/failure of a drive roller lo-
cated upstream of the target sensor
• Remaining paper near the target sensor
• Soiling on the target sensor
• Displacement of the target sensor position
• Failure of the target sensor
• Soiling (grease)/deterioration/failure of a drive motor located
upstream of the target sensor
• Soiling (paper dust)/deterioration/failure of a drive roller lo-
cated upstream of the target sensor
• Door open during printing
• Opening/closing of the door
• Turning OFF and then ON the power
• Error near the target sensor (soiling/displacement/failure of
the sensor, error in harness/open circuit of harness, soiling
(grease)/deterioration/failure of a drive motor, or soiling (pa-
per dust)/deterioration/failure of a drive roller)
• Remaining paper in the machine
• Soiling on the target sensor
• Failure of the target sensor
• Foreign matter on the target sensor (paper dust, paper lint)
• Opening/closing of the door after jam removal
• Turning OFF and then ON the power after jam removal
• Difference in paper size
• Wrong paper size setting
• Error in the Document Size Sensor (soiling/displacement/
failure of the sensor)
• Error in the Paper Size Detection Unit (failure of mechanical
structure for size detection, failure of the Guide Plate, or fail-
ure of the Cassette Size Switch)
• Using at problem analysis.
