    Not too baffling. Replace the sensors, including the upper limit sensor located at the rear side of the adf on the frame. You can see it when you open the adf cover. The lift table moves up, lifts the primary feed assembly up and stops when the flag blocks the sensor. If it is driving past and coding, the sensor is most likely bad or getting weak.

    SPDF D642 Parts manual? I have gone through my manuals and can not find one for the parts for the SPDF anywhere. Does anyone have one ? I seem to have every parts and service manual for ricoh and not that one of course! I want to order the lift motor and sensors for that unit.


    Thank you!

    I never had to replace one of those, so I'm not sure, but it looks to me it's the stepper motor mentioned here. You need to look at it and compare to the one you have.
