Jam Code
Jam Type
Type
Overview of detection
Check items (in arbitrary order)
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.
- 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 located upstream of the
target 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.
- 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 located upstream of the
target sensor
Door open
A door open jam occurs when a sensor
detected door open during printing
operation.
- Door open during printing
Sequence
A sequence jam occurs when there
was an error in sensor detection signal
at printing operation sequence.
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.
- 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 (paper dust)/deterioration/
failure of a drive roller)
Power-on
A power-on jam occurs when a sensor
detected ON state at power-on.
- 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)

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 occurrence 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, service
technician should perform remedial
work for the error code.
- Opening/closing of the door after jam
removal
- Turning OFF and then ON the power
after jam removal
Size error
A size error jam occurs when the
difference between 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.
- 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
failure of the Cassette Size Switch)
Different media A different media jam occurs when the
paper type specified from a PC or the
Control Panel differed from the one
detected by the sensor.
- Difference in paper type
- Wrong paper type setting
- Error in the Transparency Sensor (soiling/
displacement/failure of the sensor)
- Soiling on the Reflection Plate of the
Transparency Sensor
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.
