077-909 IOT Static Jam
BSD on:CH3.1
Description
At Power ON or with Interlock closed, one of the sensors of IOT sensed paper.
Check Items
Check NVM[742-003](IOT Jam Sensor Chain No.) and NVM[742-004](IOT Jam Sensor Link No.) to identify which sensor has caused IOT Static Jam.
E.g.: If the current value in NVM[742-003] is [77] and the current value in NVM[742-004] is [108], it indicates the cause is DC330[077-108]=IOT Exit Sensor. Turning OFF the power clears the values in NVM[742-003] and NVM[742-004]. The suspected sensors are as follows:
[071-100] Tray 1 Pre Feed Sensor
[072-100] Tray 2 Pre Feed Sensor
[073-100] Tray 3 Pre Feed Sensor
[074-100] Tray 4 Pre Feed Sensor
[010-201] Fuser Exit Sensor
[077-105] Invert In Sensor
[077-106] Invert Path Sensor
[077-100] Trans Path Sensor 1
[077-101] Trans Path Sensor 2
[071-101] Feed Out Sensor 1
[072-101] Feed Out Sensor 2
[073-101] Feed Out Sensor 3
[074-101] Feed Out Sensor 4
[077-103] Pre Regi Sensor
[077-104] Regi Sensor
[077-107] Invert Out Sensor
[077-108] IOT Exit Sensor
[077-109] Dup In Sensor
[077-110] Dup Path Sensor 1
[077-111] Dup Path Sensor 2
[077-112] Dup Out Sensor
[075-100] MSI Pre Feed Sensor
[075-101] MSI Feed Out Sensor
Check the machine inside for pieces of paper.
Signal line from the sensor for a short to the frame
Check if the Sensor actuator improperly returns.
Sensor for light from outside
Check for a drop in the power voltage to the sensor.
