F1-10 Error on MX2700n

[Highwood]

I have an mx2700 with the fnx1 finisher that goes into the f1-10 error as soon as the macine boots up.
The stapler unit and finisher control board have both been changed but that has not fixed the problem.

Since you have replaced stapler and finsher control I would dbl check all harnesses and connections, after that, I think its the PCU next. Have you talked with Sharp about it?

[gherkin]

check the harness from the finisher pwb to the stable unit, it might have stretched or kinked,

Check the wiring betven the PCB board and the stapler.
