SYMPTOM

J430: LCT1 Paper Feed Sensor (Tray1)
J431: LCT1 Paper Feed Sensor (Tray2)

CAUSE

Paper cannot be fed, because the spring pin [A] located at the rear side of the paper feed
belt unit [B] (of the main machine or Vacuum Feed LCIT RT5100) is not connected to the
coupling [C].

This photo shows the improper
condition where the spring pin is
not connected to the coupling.
