Techat, thanks for your post. Can you please confirm which cable that is. There's a cable that has 2 screws on each end that screw into the ADF and main copier frame (near the side bypass tray). Then there's other cables that appear to be power-type cables.
Thank you.

U CAN'T MISS IT/ u mentioned that u unplugged and plugged back in
make sure machine is OFF and unplugged from wall outlet before removing and plugging in any interface cables

Thanks. Will do continuity check on that cable. The other cable is a SCSI type cable that has (too) many small contacts.
BTW, that SCSI-type data cable to me looked to be a bit more worn. Could the above described error be generated from that cable?
Teckat, while the unit sits, it is going into an error mode that disables the copier. The error code showing is 743-0000.
Might this still be associated with the interface cable problem? I understand this code reads: "The reader controller PCB detects a fault in the communication between the main controller PCB and the reader controller PCB."
I think you just answered your own question. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Thanks Blackcat for your post. Can you please clarify what part is the "reader controller PWB" that you've bolded. Is that the cable, or another part? Thank you.
You know the connector that teckat has been illustrating? It connects directly to the reader controller circuit board. =^..^=

Have u checked and inspected the interface cable on both ends

Teckat, thanks for your post. Have now confirmed that the cables are OK, checked continuity as suggested in the forum & even tried cables on another IR3300i thereby confirming that the problem is not a cable problem.
Can you suggest whether it likely requires the replacement of the circuit board located in the ADF that the interface cable plugs into?? The circuit board had its red LED flashing on booting up & seems to have power in it, but the before described error codes persist & the ADF will not function. Specifically, when paper is placed into the ADF, it does not turn on (green indicator ontop) nor do the ADF rollers move thereby recognizing the paper in the ADF.
Blackcat's suggested diagnostic states to replace the ADF controller PWB - which circuit board might that be, and then replacing the reader controller PWB.
Thank you
