I have a problem with finisher. After machine power on i cant do booklet.All accesories on but booklet trimmer off, bottom of the screen displays "failure Finisher". after "Ready to copy" words "functions are limited". The finisher can staple. If i energize relay on booklet trimmer, booklet trimmer fully functional. I check it from booklet trimmer service. in the machine itself has no error codes ( I think aboutsaddle controller pcb because from main finisher pwb comes +5 and +24 and led on the saddle pwb not lit, but im not sure that replace pwb solve my problem(((
