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 lo-
cated 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 lo-
cated 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 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. • 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)
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 avoid-
ance An error avoidance jam occurs when an error in the
machine (excluding parts failure) was detected.
Printing operation is suspended to avoid error occur-
rence 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 tech-
nician 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 fail-
ure of the Cassette Size Switch)
Different me-
dia 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/fail-
ure of the sensor)
• Soiling on the Reflection Plate of the Transparency Sensor
