C6500

[ReoNeo]

Hello Friends
Have anyone some hint on error code 6704 on a C6500.

I assume you have read the manual:

C-6704* When scanning an image, compression
process from scanner
to memory is not completed
within the specified time. Evolution
from scanner to page memory
is not completed within the
specified time. SVV is not
detected within the specified
time.
Image processing board
(IPB)
I/F board (IFB)
Image memory control board
(IMCB)

Overall control board (OACB


I would suggest a firmware re-load/upgrade. A have a look at "Compression mode" for the scanner. On or off?

Now have three machines with this code. Any print job including internal test prints causes the code to appear.

One machine each at firmware 40, 50 and 60. Upgrade apparently has no effect.

Board Replacements include IP and Memory Control, am trying IF and OACB on one machine today - will post the results.

S V V signal or process is not mentioned by that name anywhere but in the Service Manual error list. Is this function a clue to what is going on?

Even internal prints?

Should be a scanning error ??

I have a c6500 with the same problem. Did you find a fix for it???

dljorg sent me a reply that the cero copier interface board caused the problem on 3 of his machines. I am going to try and get a new board. If anyone has a spare for sale let me know EFI p/n 45053205. Not sure about the ref in IC303 part book. I am pretty sure it is the ref #10 . Nationwide has them for about $400.

Creo is not an efi machine that I am aware of. Also re-seat the boards on the back and clean the connectors also. I had two machines that during moving and setup these came loose and caused this same issue. It still could be the interface pwb for the creo but I would try re-seating boards as that is cheaper.

I have a Cero80 (ikon c650 ikon power pro) believe it is IC303 (black case tower). You are right it is not EFI.
Yes you are right to clean it out and reseat the boards. Will reseat the machine boards and do a dusting and cleaning on the creo. Thank you for the information.
