Stapler Cable
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
continuity, replace the finisher control board. If +5 V
dc is present, replace the stapler.
