Occurrence 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 judges that a jam has occurred, the printing operation is stopped and the jam is notified to the Main
Controller at the same time. The following shows the jams that are detected.
Jam name Details
Pickup Delay Jam 1 At paper pickup, the TOP Sensor (PS2) does not detect the paper leading edge although a
specified period of time has passed.
Pickup Delay Jam 2 Paper was picked up from the first, second or third cassette of the Paper Feeder, but the PF
Media Path Sensor (PS432) of the paper source failed to detect the paper leading edge.
Pickup Delay Jam 3 Paper was picked up from the second or third cassette of the Paper Feeder, but the PF Media
Path Sensor (PS432) located between the PF Media Path Sensor (PS432) and the TOP Sensor
(PS2) of the paper source failed to detect the paper leading edge.
Pickup Stationary Jam 1 The TOP Sensor (PS2) does not detect the paper trailing edge although a specified period of
time has passed since this sensor (PS2) detected the paper leading edge.
Fixing Delivery Delay Jam 1 The Fixing Delivery Sensor (PS13) does not detect the paper leading edge although a specified
period of time has passed since the TOP Sensor (PS2) detected this paper leading edge.
Fixing Delivery Stationary Jam 1 The Fixing Delivery Sensor (PS13) does not detect the paper trailing edge although a specified
period of time has passed since this sensor (PS13) detected the paper leading edge.
Door Open Jam 1 The door open was detected during printing and feeding paper.
Wrapping Jam 1 The Fixing Delivery Sensor (PS13) detected the paper trailing edge before a specified period of
time had passed since this sensor (PS13) detected the paper leading edge.
