Re: SC186-00 on Metis series - what I found today

Cleaning the glass has always been the first step in trouble shooting CIS and back side image quality on SPDF models. Also, depending on the model, clean the reference plate/roller for the CIS. I have seen machines with a roller where one of the roller springs has come off and caused side to side image variations.

Specifically, my symptom was this: Power machine on, J001 misfeed in ARDF. Open and close door, misfeed goes away and immediately returns. On the third time it pops the code.

Service manual says for SC186:

Metis is not covered in Goose's Guide. From Goose's Guide for the C6501/C7501 and the MP 9001:

SC 186	CIS error Check and reseat cn210 and 220 on adf main pcb
SC 186	CIS LED error - CIS defective
SC 186	Harness from CN 210 to CIS pinched on frame ,repair and reroute.

There are 3 cables connected to the CIS unit. The harnesses connected to cn 210 and cn 220 are the two smaller ones the go to the ADF main board. Inspect both them for damage and reconnect them at both ends. If both harnesses are good and reconnecting them does not clear the problem, the only other option is replacing the CIS unit. The one used for the C6501 and MP 4002 is a different part number and costs $1195.85 from Ricoh. I had one go out on a MP 9001 yesterday. Luckily I have a C6501 parts machine that I was able to take one from.
