k3 finisher

Now I have another finisher giving me a 531-002, replaced stapler, checked switches, no luck. Any Ideas?

K3's have been around a while...

Wiring harness that travels back and forth with the carriage, comes to mind. I can't recall the error code, but all those signals pass through that umbilical to the controller board...

Check for a faulty wiring harness to MSW2.This could cause this code.

Is that the one up on the Swing Guide, under the metal shield???

I believe so.

Make sure both the door switches are interlocked. I don't remember if that gave me a 531 or a 532 but it's worth a check. MSW2 can definately cause that code. Just do yourself a favor and remove the switch from the swing assembly to check it. It can look good and feel tight if you check it while it is still in the assembly.
