Jam DetectionThe sensors are provided at the locations shown below to detect the presence of paper and whether the paper is being fedcorrectly.PS3PS4PS5Symbol Name Symbol NamePS3 TOP Sensor PS5 Fixing Paper Width SensorPS4 Fixing Delivery SensorOccurrence of a jam is judged by whether paper is in the sensor area at the timings stored in the DC Controller.When the DC Controller judged the Jam has occurred, printing operation is stopped and the occurrence of the jam is notified tothe Main controller at the same time.Jam ListJam name DetailPickup stationary Jam The TOP Sensor (PS3) does not detect the back end although a specified period of time has passed afterdetection of the leading edge.Fixing delivery delay Jam The Fixing Delivery Sensor (PS4) does not detect the leading edge although a specified period of time haspassed after the TOP Sensor (PS3) detected the leading edge.Fixing delivery stationaryJamIn the case the Fixing Delivery Sensor (PS4) cannot detect the back end although a specified period of timehas passed after the TOP Sensor (PS3) detected the back end.Internal residual Jam In the case the following sensors detected the presence of paper before/after the power ON, closing the doorand printing operation.• Top Sensor (PS3)• Fixing Delivery Sensor (PS4)• Fixing Paper Width Sensor (PS5)Door open Jam The door open was detected during printing and feeding paper.Fixing wrap Jam The time from when the Fixing Delivery Sensor (PS4) detected the paper leading edge until the sensor OFFstatus of the sensor was detected was shorter than the predetermined time.Reverse Assembly Jam In the case that the Fixing Delivery Sensor (PS4) cannot detect the paper leading edge although a specifiedperiod of time has passed after the paper was reversed in 2-sided printing.Duplex Re-pickup As-sembly JamIn the case that the TOP Sensor (PS3) cannot detect the paper leading edge although a specified period oftime has passed after the Fixing Delivery Sensor (PS4) detected the paper leading edge.2.
