If the error occurs and there is no staple jam, check to ensure that
connectors CN5 on the stapler and PJ1 on the finisher control
board are properly connected. Make sure that the finisher set
switch is activated. Measure for +5 V dc between pins 11 and 12
on stapler connector CN5. If +5 V dc is not present, check for
continuity on the stapler to finisher control board cable. If there is
no continuity on any pin position, replace the cable. If there is

replace the stapler.
