1 Stapler
Staple cartridge holder
Check for jammed staples in the stapler.
Clear the staple jam, go into diagnostic
mode, and run a staple test. If the problem
reoccurs, replace the staple cartridge
holder. If this does not resolve the problem,
replace the stapler.
2 Stapler
Finisher control board
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.
