077-909 IOT Static Jam Fault BSD On BSD 8.10 Registration
Description One of the IOT sensors detected paper when wh en power was turned on or o r when an interlock was closed.
Initial Action Perform the following:
Check Jam Clearance display on UI U I to determine suspect area since any of the th e paper path sensors could generate this fault. Clear any paper jam. Switch the power Off then On. Check if the Registration Sensor actuator is operating properly. Check for any light leaks. Check for a change or drop in the power voltage at the customer site. Enter NVM 742-003 Static Jam Sensor Chain Link No. = Chain Link No. of sensor which did not initialize.
Procedure If the problem persists after performing the Initial Actions, check the following sensors in Table 1 to determine which sensor is causing the problem. Ex ecute Component Control and actuate each sensor as appropriate to determine if the display changes on actuation.

To check a suspect transmissive sensor circuit go to OF 99-2. If the sensor is a reflective type go to OF 99-1 Reflective Sensor RAP. The list below lists which of the sensors is which type.
Reflective - Pre Reg Sensor, Registration Sensor, and OHP Transparency Sensor Transmissive - Invert In Sensor, Duplex In Sensor, Duplex Path Sensor, Duplex Out Sensor, IOT Exit Sensor.
If the problem persists after checking the sensors and related wiring, replace the MCU PWB ( PL 11.1).
