7.2 Detecting Jams

7.2.1 Delay Jams

7.2.1.1 Delay Jam in Pickup Assembly

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i

Delay Jam in Pickup Assembly

The registration sensor cannot detect the leading edge of paper within the jam detection time interval after paper pickup started.
7.2.1.2 Delay Jam in Delivery Assembly (Paper Leading Edge Jam at Delivery Sensor/Wound Paper Jam at Fixing
Assembly)
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
Paper Leading Edge Jam at Delivery Sensor
The delivery sensor cannot detect presence of paper within the prescribed time after the registration clutch has been turned on.
Wound Paper Jam at Fuser
The delivery sensor has detected absence of paper within the prescribed time after it detected presence of paper (within the prescribed
time after the registration clutch had been turned on).

7.2.2 Stationary Jams

7.2.2.1 Stationary Jam in Pickup Assembly

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i

Stationary Jam in Pickup Assembly

The registration sensor does not detect absence of paper within the prescribed time before the next leading edge of fed paper reaches the registration sensor.
7.2.2.2 Stationary Jam in Delivery Assembly (Paper Trailing Edge Stationary Jam at Delivery Sensor/Stationary Jam at
Delivery Sensor)
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
Paper Trailing Edge Stationary Jam at Delivery Sensor
The delivery sensor cannot detect absence of paper within the prescribed time after the registration sensor has been turned off.
Stationary Jam at Delivery Sensor
The delivery sensor cannot detect absence of paper within the prescribed time after it has detected the leading edge of paper.

7.2.3 Other Jams

7.2.3.1 Door Open Jam

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i

Door Open Jam

The door is opened when paper to be printed is in the paper feed path.

7.3 Cassette Pick-Up Unit

7.3.1 Overview

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
The paper picked up from the cassette is fed to the registration roller using the vertical path roller driven by the main motor (M204). The registration roller is not
rotating when paper reaches there, so an arch is formed at the leading of the paper to prevent skewing. The DC controller PCB turns on the registration clutch
(CL203) at the prescribed timing to transfer the main motor rotation to the registration roller, thus feeding the paper to the delivery tray through the transfer, sepa-
