After that, the sensorstill cannot detect the leading edge of paper within the specified time, it is judged as a pickupjam.Pickup Stationary JamWhen the TOP Sensor (PS204) cannot detect the trailing edge of paper after the specifiedtime has passed since it detected the leading edge of paper, it is judged as a pickupstationary jam.Delivery Delay JamWhen the Fixing Delivery Sensor (100V:PS915, 230V:PS9150) cannot detect the leadingedge of paper after the specified time has passed since the TOP Sensor (PS204) detectedthe leading edge of paper, it is judged as a delivery delay jam.Delivery Stationary JamAfter judging that it is not a Fixing paper wrap, execute the detection of delivery stationaryjam.When the Fixing Delivery Sensor (100V:PS915, 230V:PS9150) does not detect no paperwithin the specified time since the TOP Sensor (PS204) detected the trailing edge of paper, itis judged as a delivery stationary jam.Fixing Paper Wrap JamAfter judging that it is not a delivery delay jam, execute the detection of Fixing paper wrapjam.It is judged as a Fixing paper wrap jam when all of the following conditions are met: after thespecified time had passed since the Fixing Delivery Sensor (100V:PS915, 230V:PS9150)detected the leading edge of paper, after the specified time had passed since the TOP Sensor(PS204) detected the leading edge of paper, and the Fixing Delivery Sensor (100V:PS915,230V:PS9150) detects no paper.Reverse Delay JamAfter judging that it is not a delivery stationary jam, execute the detection of reverse stationaryjam.When the Duplex Reverse Sensor (PS201) does not detect paper after the specified time haspassed since the Fixing Delivery Sensor (100V:PS915, 230V:PS9150) detected the trailingedge of paper, it is judged as a reverse delay jam.Reverse Stationary JamWhen the Duplex Reverse Sensor (PS201) cannot detect the trailing edge of paper after thespecified time has passed since the sensor detected the leading edge of paper, it is judgedas a reverse stationary jam.Internal Residual JamWhen a paper is detected by the TOP Sensor (PS204), Fixing Delivery Sensor (100V:PS915,230V:PS9150), Paper Width Sensor (PS205), or Duplex Reverse Sensor (PS201) at the timeof starting initial rotation, it is judged as an internal residual jam.Door Open JamWhen a door-open is detected while feeding papers, it is judged as a door open jam.Service TasksAt Parts ReplacementNo work is accompanied with parts replacement.MaintenanceNo periodically replaced parts, durable parts or periodical service is set for this product.Notes On Service WorksNo periodically
