Code Name Sensor No. Description
0104 Delay jam in paper pickup section SR710 The registration sensor cannot detect the leading edge of paper from the moment paper
pickup starts to the moment the jam detection time is reached.
0208 Stationary jam in paper pickup section SR710 The registration sensor cannot detect the no paper status specified time before the leading
edge of the picked up paper reaches this sensor.
010c Delay jam in deliver section SR710, SR6005 - The fixing delivery sensor cannot detect presence of paper within the specified time after
turning on of the registration clutch.
- The fixing delivery sensor detected absence of paper within the specified time after the
sensor had detected presence of paper within the specified time after turning on of the
registration clutch.
- The No.1 delivery sensor cannot detect presence of paper within the specified time after
turning on of the fixing delivery sensor.
0210 Stationary jam in delivery section SR710, SR6005 - The fixing delivery sensor cannot detect absence of paper within the specified time after
turning off of the registration clutch.
- The fixing delivery sensor cannot detect absence of paper within the specified time after
the sensor detected the leading edge of paper.
- The No.1 delivery sensor cannot detect absence of paper within the specified time after the
sensor detected the leading edge of paper.
0214 Stationary jam in machine SR706, SR710,
SR6001, SR6005 Paper was detected in the paper transport path during initial rotation, during automatic
delivery, at the end of cleaning, or at reception of an emergency stop command.
1118 Door open jam SR720 The door was opened when there was printing paper in the transport path.
0221 Reverse section JAM SR706, SR715 This jam is applied when the double-fed paper drops on the back of the host machine.
The machine determines the reverse section jam if the paper length that is detected by the
reverse sensor (SR706) is 50mm or more longer than the paper length that is detected by the
delivery sensor (SR715).
0228 Reverse re-pickup section jam SR710 The machine determines the reverse re-pickup jam if the registration sensor (SR710) cannot
detect the presence of paper within the specified time (t) after the duplexing pickup starts.
Specified time (t) differs depending on the feeding speed.
1/1 speed: approx. 2.0 sec
4/5 speed: approx. 2.5 sec
1/2 speed: approx 4.0 sec
Code Name Sensor No. Description
0001 ADF paper trailing edge sensor (SR719)
not reaching (delay jam) SR719 The leading edge of paper does not reach the ADF paper trailing edge sensor (SR719) within
1.8 sec after the trailing edge of precedent page passes through the ADF paper trailing edge
sensor (SR719) in 1-sided multiple jobs.
The leading edge of paper does not reach the ADF paper trailing edge sensor (SR719) within
1.2 sec after reverse operation starts in 2-sided job.
0002 ADF paper trailing edge sensor (SR719)
stray (stray jam) SR719 The trailing edge of paper does not passes through the ADF paper trailing edge sensor (SR719)
within 3.4 sec after the leading edge of paper reaches the ADF paper trailing edge sensor
(SR719) in 1-sided job.
The trailing edge of paper does not passes through the ADF paper trailing edge sensor (SR719)
within 3.5 sec after the leading edge of paper reaches the ADF paper trailing edge sensor
(SR719) in 2-sided job.
0094 Initial stationary (in-body residual jam) SR719 The ADF paper trailing edge sensor (SR719) detects paper at power-ON.
0095 Pickup NG SR718 The paper is removed from the ADF original tray within 0.1 sec after the start key is pressed.
