The machine is equipped with 3 jam sensors and 1 jam switch used to motor the movement of paper.
The presence/absence of paper or of a jam is checked at such times as programmed in advance in the CPU of the DC controller PCB and in relation to the presence/
absence of paper over a specific sensor at a given time. If the machine detects a jam, it will turn off the main
motor (M1), and will indicate a jam message in the control panel.

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /
The machine groups jams into 7 types. When a jam occurs, be sure to remove it, and start over the operation.
Pickup Delay Jam
After execution of a pickup retry, the registration sensor (SR11) does not detect the leading edge of paper within a specific period of time. Or after the duplex drive
solenoid (SL1) is on, the registration sensor (SR11) does not detect the leading edge of paper within a specific period of time.
Delivery Sensor Delay Jam
After the registration sensor (SR11) has detected the leading edge of paper, the delivery sensor (SR5) does not detect the leading edge of paper within a specific
period of time.
Pickup Stationary Jam
After the registration sensor (SR11) has detected the leading edge of paper, the registration sensor (SR11) does not detect the trailing edge of paper within a specific
period of time.
Delivery Sensor Stationary Jam
After the registration sensor (SR11) has detected the trailing edge of paper, the delivery sensor (SR5) does not detect the trailing edge of paper within a specific
period of time.
Wound Paper Jam at Fuser
The delivery sensor (SR5) has detected absence of paper within the prescribed time after it detected presence of paper.
Initial Jam
- When presence of paper is detected by the registration sensor (SR11) or delivery sensor (SR5) at the start of waiting.
- When presence of paper is detected by the delivery sensor (SR5) during waiting.
Left door/Front Cover Open Jam
During paper feeding, the interlock switch (SW2/SW3) has detected OFF.
