Hi guys,
I had a pain in the arse call a few weeks back. Customer had a MPC2800 with the hanging SR3050 finisher. Machine would make 1 copy set then go into SC621 (finisher communication trouble). When we got there we could not replicate it for a while and then it happened. We re seated all the connectors in the finisher and the I/O board and the code was gone. Next day it came back.
Ricoh suggested we start swapping boards:
Finisher pwb
I/O pwb
BICU
All those were changed and code came back.
After fighting with the machine for a few hours i started to notice a clunk just before the SC621 came up. I ran the finisher with the door open and the code would not appear. When i closed the door the code would happen. Long story short:
A previous tech tore that finisher apart. The wiring harness that goes into the staple head has a tie strap on it and gets hooked into a wire holder. The tie strap was on the wrong side of the wire holder and allowing the wires to rub on the metal door interlock switch when the staple head came back to the home position and swung over towards the door for staple refilling.
Before you start swapping boards check this out first.
I have attached a picture of where this holder is.
