Any one know that how to reset this codes, after go trouble shooting but not reset and trouble code still showing.

They are "abort" codes

If it won't reset I would suspect a bad board in Doc feeder. If you have another machine I would swap whole doc feeder.

Since both codes show an issue with doc feeder I would disconnect & unset the the doc -feeder in service mode, then try and reset code.
Also try updating firmware or using reset tool as last resort, can't hurt.



C-FCAB code:

MFP board (MFPB)
• DSC board/1 (DSCB/1)
• DSC board/2 (DSCB/2)
• EFI relay board
(EFIRYB: VI-506)
• Dual scan image
processing board
(DSIPB)

C-FFCB Code:
MFP board (MFPB)
• DSC board/1 (DSCB/1)
• DSC board/2 (DSCB/2)
• Dual scan image
processing board
(DSIPB)

DS board JPEG watchdog timer error

Perhaps unrelated, but I have changed a few dual scan boards and the associated cables. =^..^=

Cat, agree the Duel scan pwb is very much related and one of the things I forgot to post.

Please don't take this wrong but if you don't know the locations of these and don't have the service manual to review which would show the locations then you shouldn't attempt to repair the machine. If you still want to repair perhaps someone or myself will send you service manual if you request it.
